Operation details

Purpose

Create embeddings. This applies the validated business action to the selected tenant or platform resource.

When to use it

Use this when the documented business action or resource creation is the intended next step.

When not to use it

Do not repeat the request blindly after an uncertain outcome. Read the resulting resource or background operation state first.

Contract

Availability

Product version: Next Product release
Licence: An active Product licence is required except for health, authentication, and licence remediation operations.
Entitlements: None
Service roles: inference
Deployment: customer managed installation
Feature state: preview

Security

Access

Sign in: Use a session cookie or Bearer session token.

Actor: Authenticated Pūnaha actor authorised for the selected tenant and resource
Permission: models.read
Resource: model_deployment / execute / *
Tenant rule: Tenant scoped unless the selected actor is performing an explicitly documented platform action. The x organization id header or authenticated session context selects the tenant. It does not grant access.
Explicit deny: An applicable explicit deny overrides an allow. Knowing or supplying a resource identifier never grants access.

Address, query and header fields

Field	Location	Presence	Type	Meaning	Limits and example
`x-request-id`	header	Optional	string	Optional caller supplied correlation identifier. Pūnaha returns the effective value in the response header.	Minimum length: 1. Maximum length: 200. Example: example request 001

Request body

Content type: application/json. Presence: Required.

Operation request. Every property documents omission, null, sensitivity, source, mutability, availability, access, and lifecycle semantics through JSON Schema and x punaha-* annotations.

Effects

Behaviour and other effects

Changes: Validates access and input, then applies the operation specific state change. A failed validation or authorisation check does not intentionally apply the requested change.
Audit events: The mutation is subject to the Product audit policy. The exact event name is operation owned and must be reviewed before publication.
Background work: No background work is inferred. The success response represents completion of the HTTP action.
External effects: No external call is inferred from the route name. Operation specific service behaviour remains authoritative.
Transaction boundary: The HTTP success or error describes the synchronous boundary. Background operations have their own observable lifecycle and may outlive the request.

Operation

Reliability

Idempotent: No
Retry: Do not retry automatically after a timeout or lost response. Read current state first.
Concurrency: Use documented If Match or resource revision fields where exposed. Otherwise read current state before changing it and handle HTTP 409 conflicts.
Consistency: The response reflects the synchronous operation boundary. Background and provider backed state can converge later and must be read through its status operation.
Timeout: Client timeouts do not cancel completed or already started server work unless the operation explicitly supports cancellation.
Request ID: Send or record x request id and retain the returned value for diagnosis.

Errors and corrections

Status	Code	Cause	Correction	Retryable	Partial work
`400`	`INPUT_REQUIRED`	input is required.	Correct the named field or rule in error.details, then submit a new request. Retrying an unchanged request will not help.	No unchanged retry	No requested mutation is expected before this failure boundary.
`400`	`INVALID_REQUEST_BODY`	The request body or supplied field values are invalid.	Correct the named field or rule in error.details, then submit a new request. Retrying an unchanged request will not help.	No unchanged retry	No requested mutation is expected before this failure boundary.
`401`	`AUTHENTICATION_REQUIRED`	A valid authenticated session or supported token is required.	Authenticate again using a supported mechanism and confirm that the credential is current.	No unchanged retry	No requested mutation is expected before this failure boundary.
`403`	`PERMISSION_REQUIRED`	The authenticated actor does not have the exact permission or resource action.	Select the correct tenant and resource, then ask an authorised administrator to grant the exact documented action if appropriate.	No unchanged retry	No requested mutation is expected before this failure boundary.
`409`	`STATE_CONFLICT`	Current resource state or a dependency prevents the requested change.	Read current state, resolve the named dependency or lifecycle conflict, and submit a deliberate new request.	No unchanged retry	The caller must read current resource or background operation state before retrying because work may have started before the failure became observable.
`423`	`LICENCE_REMEDIATION_REQUIRED`	The installation is restricted and permits only licence remediation actions.	Complete the indicated licence or membership remediation before retrying Product work.	No unchanged retry	The caller must read current resource or background operation state before retrying because work may have started before the failure became observable.
`500`	`INTERNAL_ERROR`	Pūnaha could not complete the operation because of an unexpected internal failure.	Retain x request id and the stable error code, avoid blind retries, and investigate the operation or contact support. Code: INTERNAL_ERROR.	No unchanged retry	The caller must read current resource or background operation state before retrying because work may have started before the failure became observable.
`503`	`DEPENDENCY_UNAVAILABLE`	A required node, database, provider, or service is temporarily unavailable.	Retain x request id, check health and the named dependency, then retry with bounded backoff when safe.	Yes, with the documented safeguards	The caller must read current resource or background operation state before retrying because work may have started before the failure became observable.

Code examples

Use a supported credential and synthetic data. Do not disable TLS checks or retry a request that changes state blindly.

cURL example

curl --request POST "$PUNAHA_URL/api/embeddings" \
  --header "Authorization: Bearer $PUNAHA_TOKEN" \
  --header "x-request-id: example-request-001" \
  --header "Content-Type: application/json" \
  --data '{"input":"example-value","model":"example-value","prompt":"example-value"}'

JavaScript example

const response = await fetch(`${PUNAHA_URL}/api/embeddings`, {
  method: "POST",
  headers: {
  "x-request-id": "example-request-001",
  "Authorization": "Bearer ${PUNAHA_TOKEN}",
  "Content-Type": "application/json"
},
  body: JSON.stringify({
    "input": "example-value",
    "model": "example-value",
    "prompt": "example-value"
  })
});

if (!response.ok) throw new Error(`Pūnaha request failed: ${response.status}`);
const result = response.status === 204 ? undefined : await response.json();

C# example

using System.Net.Http.Headers;
using System.Text;

using var client = new HttpClient { BaseAddress = new Uri(punahaUrl) };
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", punahaToken);
using var request = new HttpRequestMessage(HttpMethod.Post, "/api/embeddings");

var json = "{\"input\":\"example-value\",\"model\":\"example-value\",\"prompt\":\"example-value\"}";
request.Content = new StringContent(json, Encoding.UTF8, "application/json");
using var response = await client.SendAsync(request);
response.EnsureSuccessStatusCode();
