Does not share it to another agent, build a snapshot or publish. Owner fields in the body are rejected. The new library member changes the agent's publication ETag. A destination that is not a permitted public address is reported later as state=failed with failure=outbound_destination_refused, not as a request error. Reference: https://docs.v2.rasen.ai/api-reference/agents/knowledge-sources/create ## Authentication - `Authorization` header (bearer token, required) — Create and manage workspace-owned keys through the existing app session routes, outside this public API. Creator and manager identities are audit actors only. Key validity follows workspace policy, expiry and explicit revocation, independently of creator membership. Do not include a workspace-selection header. ## Request ### Path parameters - `agent_id` (string, required) — Resource identity within the authenticated workspace. ### Headers - `Idempotency-Key` (string, required) — Stable key per logical intent, 1–255 printable characters. Persist it before sending. Retry the same key/body after an uncertain result for 24 hours. A changed body conflicts. Beyond retention, reconcile the resource before retrying; this is not permanent deduplication. Current authorization is rechecked on replay. Evaluation order: authenticate and check current authorization; look up intent; replay its stored receipt before checking the current revision; only a new intent evaluates If-Match and executes. Fingerprint includes method, path, body and original If-Match. A changed request returns idempotency_key_reused. The server stores only a keyed (HMAC) fingerprint, and no error or response ever returns a fingerprint or hash of a request. In-flight intent returns 409 idempotency_in_progress with Retry-After; retry the same intent after reconciliation. Receipts describe that attempt, not current resource state. A replay returns the original status code and body, with the response header Idempotent-Replayed: true. ### Body (application/json) This endpoint expects an AgentSourceCreate. - `AgentSourceCreate` - `kind`: `url` (url) - `name` (string, required) - `url` (string, required) - `resource_key` (string, optional) — Optional caller-chosen resource key: an opaque external identifier that matches your own record (for example a CRM ID, a configuration-file ID or a UUID) to this resource. Rasen still generates the canonical id; use id in paths and references. Case-sensitive, compared exactly, never normalized or parsed. 1-128 characters from A-Z a-z 0-9 . _ : ~ - and starting with a letter or digit; UUIDs and ULIDs are valid. Unique per resource type within one workspace; separate environment workspaces can reuse the same key. Set only at creation and immutable afterwards. A create with a key that already exists returns 409 resource_key_conflict with details.existing_id; it never updates or returns the existing resource. Not an Idempotency-Key: that header identifies one request intent for 24 hours, and a same-intent replay returns its original receipt before the resource-key check runs. Uniqueness includes archived resources. A key becomes free again only after its resource is permanently deleted or erased (a deleted secret or a deleted knowledge source); archive never frees it. - `kind`: `text` (text) - `name` (string, required) - `text` (string, required) — Source text, at most 262,144 characters. - `resource_key` (string, optional) — Optional caller-chosen resource key: an opaque external identifier that matches your own record (for example a CRM ID, a configuration-file ID or a UUID) to this resource. Rasen still generates the canonical id; use id in paths and references. Case-sensitive, compared exactly, never normalized or parsed. 1-128 characters from A-Z a-z 0-9 . _ : ~ - and starting with a letter or digit; UUIDs and ULIDs are valid. Unique per resource type within one workspace; separate environment workspaces can reuse the same key. Set only at creation and immutable afterwards. A create with a key that already exists returns 409 resource_key_conflict with details.existing_id; it never updates or returns the existing resource. Not an Idempotency-Key: that header identifies one request intent for 24 hours, and a same-intent replay returns its original receipt before the resource-key check runs. Uniqueness includes archived resources. A key becomes free again only after its resource is permanently deleted or erased (a deleted secret or a deleted knowledge source); archive never frees it. ## Response ### 202 Add agent-owned URL or text. - `id` (string, required) — Opaque kb identifier. Do not parse its contents. - `name` (string, required) - `kind` (string, required) — Open response vocabulary. Preserve unknown values; never assume they mean success. - `state` (string, required) — pending and ingesting are in progress: keep polling. Settled states: ready (retrieval-ready), fallback (text could not be indexed but can be frozen as bounded prompt context when the source is in an agent library), failed (read failure), archived (hidden from new library selection; retained published evidence keeps working). Open response vocabulary. Preserve unknown values; never assume they mean success. - `revision` (string, required) - `created_at` (datetime, required) - `failure` (string, required, nullable) — Safe registered reason. - `content_sha256` (string, required, nullable) - `content_bytes` (integer, required, nullable) - `media_type` (string, required, nullable) - `ingested_at` (datetime, required, nullable) - `updated_at` (datetime, required) - `owner` (SourceOwnerRead, required) - `resource_key` (string, required, nullable) — Optional caller-chosen resource key: an opaque external identifier that matches your own record (for example a CRM ID, a configuration-file ID or a UUID) to this resource. Rasen still generates the canonical id; use id in paths and references. Case-sensitive, compared exactly, never normalized or parsed. 1-128 characters from A-Z a-z 0-9 . _ : ~ - and starting with a letter or digit; UUIDs and ULIDs are valid. Unique per resource type within one workspace; separate environment workspaces can reuse the same key. Set only at creation and immutable afterwards. A create with a key that already exists returns 409 resource_key_conflict with details.existing_id; it never updates or returns the existing resource. Not an Idempotency-Key: that header identifies one request intent for 24 hours, and a same-intent replay returns its original receipt before the resource-key check runs. Uniqueness includes archived resources. A key becomes free again only after its resource is permanently deleted or erased (a deleted secret or a deleted knowledge source); archive never frees it. - `poll_after_seconds` (integer, required, nullable) — Seconds to wait before the next read while state is pending or ingesting. Null when the state is settled. ## Errors ### 400 Bad Request Error Invalid input or cursor. Correct the request. - `error` (ErrorResponseError, required) — Only code and message are required. Rasen sends details, request_id and retry on every error, but clients must parse an error that lacks them, so a typed error is never lost to a parsing failure. ### 401 Unauthorized Error Invalid, expired or revoked API key. Creator departure or membership changes do not invalidate a workspace key. - `error` (ErrorResponseError, required) — Only code and message are required. Rasen sends details, request_id and retry on every error, but clients must parse an error that lacks them, so a typed error is never lost to a parsing failure. ### 403 Forbidden Error Operation not allowed by current credential or workspace access. - `error` (ErrorResponseError, required) — Only code and message are required. Rasen sends details, request_id and retry on every error, but clients must parse an error that lacks them, so a typed error is never lost to a parsing failure. ### 404 Not Found Error Resource absent or not visible in this workspace. - `error` (ErrorResponseError, required) — Only code and message are required. Rasen sends details, request_id and retry on every error, but clients must parse an error that lacks them, so a typed error is never lost to a parsing failure. ### 409 Conflict Error Conflict. Not retryable: read the current state, fix the request and send a new request. The one exception is idempotency_in_progress, which carries Retry-After: wait, then resend the identical request with the same Idempotency-Key. The operation lists its codes in x-error-codes; branch on error.code and, for conflict, error.details.reason. - `error` (ErrorResponseError, required) — Only code and message are required. Rasen sends details, request_id and retry on every error, but clients must parse an error that lacks them, so a typed error is never lost to a parsing failure. ### 413 Content Too Large Error Body or upload exceeds its allowed limit. - `error` (ErrorResponseError, required) — Only code and message are required. Rasen sends details, request_id and retry on every error, but clients must parse an error that lacks them, so a typed error is never lost to a parsing failure. ### 429 Too Many Requests Error Rate limited. Respect Retry-After and retry the same intent where permitted. - `error` (ErrorResponseError, required) — Only code and message are required. Rasen sends details, request_id and retry on every error, but clients must parse an error that lacks them, so a typed error is never lost to a parsing failure. ### 500 Internal Server Error Internal error. The effect may have happened. Retry the same request with the same Idempotency-Key; read the resource before creating a new intent. For an operation that takes an Idempotency-Key, a client retry with the same key is safe: the server replays the stored outcome if the first attempt took effect; if the first attempt had no effect, the retry performs the operation once. Never retry with a new key. - `error` (ErrorResponseError, required) — Only code and message are required. Rasen sends details, request_id and retry on every error, but clients must parse an error that lacks them, so a typed error is never lost to a parsing failure. ### 503 Service Unavailable Error Service unavailable. Respect Retry-After where present. For an operation that takes an Idempotency-Key, a client retry with the same key is safe: the server replays the stored outcome if the first attempt took effect; if the first attempt had no effect, the retry performs the operation once. Never retry with a new key. - `error` (ErrorResponseError, required) — Only code and message are required. Rasen sends details, request_id and retry on every error, but clients must parse an error that lacks them, so a typed error is never lost to a parsing failure. ## Types ### SourceOwnerRead - `type`: `workspace` (workspace) - `type`: `agent` (agent) - `agent_id` (string, required) — Opaque agent identifier. Do not parse its contents. ### ErrorResponseError Only code and message are required. Rasen sends details, request_id and retry on every error, but clients must parse an error that lacks them, so a typed error is never lost to a parsing failure. - `code` (string, required) — Stable code. Branch on code (and details.reason for conflict), never on message. Each code has one HTTP status; see components.x-error-catalog. - `message` (string, required) — Safe description; no provider payload or submitted secrets. - `details` (map from string to any, optional) — Safe code-specific details. The public fields for each code are listed in components.x-error-catalog. Details never contain a request fingerprint, a hash of a request, secret material or another tenant's data. forbidden may include required_capabilities (a list). - `request_id` (string, optional) — Same value as the X-Request-Id header. Quote it to support. - `retry` (string, optional) — Retry class of this code: no (fix the request or state first), yes (retry the same request and the same Idempotency-Key), retry_after (wait for Retry-After, then retry the same request). Open response vocabulary. Preserve unknown values; never assume they mean success. ## Examples **Request** ```json { "kind": "text", "name": "Parking notes", "text": "Parking is free after 6 pm.", "resource_key": "kb:parking:v1" } ``` **Response** ```json { "id": "kb_01j00000000000000000000000", "name": "example", "kind": "url", "state": "pending", "revision": "example", "created_at": "2026-09-25T10:00:00Z", "failure": null, "content_sha256": "example", "content_bytes": 0, "media_type": "example", "ingested_at": "2026-09-25T10:02:00Z", "updated_at": "2026-09-25T10:06:00Z", "owner": { "type": "workspace" }, "resource_key": "3f8e5a0c-9d1b-4c7e-a2f4-6b0d9e1c7a55", "poll_after_seconds": 1 } ``` **SDK Code** ```python agents_knowledgeSources_create_example import requests url = "https://api.v2.rasen.ai/v1/agents/agent_id/knowledge/sources" payload = { "kind": "text", "name": "Parking notes", "text": "Parking is free after 6 pm.", "resource_key": "kb:parking:v1" } headers = { "Idempotency-Key": "intent-appointment-001", "Authorization": "Bearer ", "Content-Type": "application/json" } response = requests.post(url, json=payload, headers=headers) print(response.json()) ``` ```javascript agents_knowledgeSources_create_example const url = 'https://api.v2.rasen.ai/v1/agents/agent_id/knowledge/sources'; const options = { method: 'POST', headers: { 'Idempotency-Key': 'intent-appointment-001', Authorization: 'Bearer ', 'Content-Type': 'application/json' }, body: '{"kind":"text","name":"Parking notes","text":"Parking is free after 6 pm.","resource_key":"kb:parking:v1"}' }; try { const response = await fetch(url, options); const data = await response.json(); console.log(data); } catch (error) { console.error(error); } ``` ```ruby agents_knowledgeSources_create_example require 'uri' require 'net/http' url = URI("https://api.v2.rasen.ai/v1/agents/agent_id/knowledge/sources") http = Net::HTTP.new(url.host, url.port) http.use_ssl = true request = Net::HTTP::Post.new(url) request["Idempotency-Key"] = 'intent-appointment-001' request["Authorization"] = 'Bearer ' request["Content-Type"] = 'application/json' request.body = "{\n \"kind\": \"text\",\n \"name\": \"Parking notes\",\n \"text\": \"Parking is free after 6 pm.\",\n \"resource_key\": \"kb:parking:v1\"\n}" response = http.request(request) puts response.read_body ``` ```java agents_knowledgeSources_create_example import com.mashape.unirest.http.HttpResponse; import com.mashape.unirest.http.Unirest; HttpResponse response = Unirest.post("https://api.v2.rasen.ai/v1/agents/agent_id/knowledge/sources") .header("Idempotency-Key", "intent-appointment-001") .header("Authorization", "Bearer ") .header("Content-Type", "application/json") .body("{\n \"kind\": \"text\",\n \"name\": \"Parking notes\",\n \"text\": \"Parking is free after 6 pm.\",\n \"resource_key\": \"kb:parking:v1\"\n}") .asString(); ``` ```php agents_knowledgeSources_create_example request('POST', 'https://api.v2.rasen.ai/v1/agents/agent_id/knowledge/sources', [ 'body' => '{ "kind": "text", "name": "Parking notes", "text": "Parking is free after 6 pm.", "resource_key": "kb:parking:v1" }', 'headers' => [ 'Authorization' => 'Bearer ', 'Content-Type' => 'application/json', 'Idempotency-Key' => 'intent-appointment-001', ], ]); echo $response->getBody(); ``` ```csharp agents_knowledgeSources_create_example using RestSharp; var client = new RestClient("https://api.v2.rasen.ai/v1/agents/agent_id/knowledge/sources"); var request = new RestRequest(Method.POST); request.AddHeader("Idempotency-Key", "intent-appointment-001"); request.AddHeader("Authorization", "Bearer "); request.AddHeader("Content-Type", "application/json"); request.AddParameter("application/json", "{\n \"kind\": \"text\",\n \"name\": \"Parking notes\",\n \"text\": \"Parking is free after 6 pm.\",\n \"resource_key\": \"kb:parking:v1\"\n}", ParameterType.RequestBody); IRestResponse response = client.Execute(request); ``` ```swift agents_knowledgeSources_create_example import Foundation let headers = [ "Idempotency-Key": "intent-appointment-001", "Authorization": "Bearer ", "Content-Type": "application/json" ] let parameters = [ "kind": "text", "name": "Parking notes", "text": "Parking is free after 6 pm.", "resource_key": "kb:parking:v1" ] as [String : Any] let postData = JSONSerialization.data(withJSONObject: parameters, options: []) let request = NSMutableURLRequest(url: NSURL(string: "https://api.v2.rasen.ai/v1/agents/agent_id/knowledge/sources")! as URL, cachePolicy: .useProtocolCachePolicy, timeoutInterval: 10.0) request.httpMethod = "POST" request.allHTTPHeaderFields = headers request.httpBody = postData as Data let session = URLSession.shared let dataTask = session.dataTask(with: request as URLRequest, completionHandler: { (data, response, error) -> Void in if (error != nil) { print(error as Any) } else { let httpResponse = response as?
