Header Parameters
Attribute this call to one of the workspace's projects. An id the workspace does not own is ignored.
Request Body
multipart/form-data
TypeScript Definitions
Use the request body type in TypeScript.
Response Body
application/json
The transcript.
TypeScript Definitions
Use the response body type in TypeScript.
application/json
The model rejected the request, for example an unsupported audio format.
TypeScript Definitions
Use the response body type in TypeScript.
An error returned by the model for this request. The HTTP status is the model's own; code usually repeats it.
application/json
Missing or invalid API key.
TypeScript Definitions
Use the response body type in TypeScript.
An error raised by pre.dev, in the OpenAI error shape with an extra predev object (absent on catalog_unavailable from the catalog listings). Branch on error.code.
application/json
The workspace cannot pay for this request. Nothing was sent to the model and nothing was charged.
TypeScript Definitions
Use the response body type in TypeScript.
An error raised by pre.dev, in the OpenAI error shape with an extra predev object (absent on catalog_unavailable from the catalog listings). Branch on error.code.
application/json
The request refers to a file, response or video job that is not this workspace's (not_found from pre.dev; nothing ran and nothing was charged), or the model could not serve the request (its own status and message, in the ModelError shape).
TypeScript Definitions
Use the response body type in TypeScript.
An error raised by pre.dev, in the OpenAI error shape with an extra predev object (absent on catalog_unavailable from the catalog listings). Branch on error.code.
application/json
Too many requests. Wait Retry-After seconds when it is present. A rate_limit_exceeded refusal is per workspace per minute (600, or 30 on the free trial). An error from the model keeps the ModelError shape.

An error raised by pre.dev, in the OpenAI error shape with an extra predev object (absent on catalog_unavailable from the catalog listings). Branch on error.code.
application/json
Unexpected error.
TypeScript Definitions
Use the response body type in TypeScript.
An error raised by pre.dev, in the OpenAI error shape with an extra predev object (absent on catalog_unavailable from the catalog listings). Branch on error.code.
application/json
The model did not answer. Retry with backoff, or send models fallbacks.

An error raised by pre.dev, in the OpenAI error shape with an extra predev object (absent on catalog_unavailable from the catalog listings). Branch on error.code.
application/json
The credit balance could not be read, so nothing ran. Retry after Retry-After seconds.
