Authorizations

Authorization

string

header

required

Bearer authentication header of the form Bearer <token>, where <token> is your auth token.

Headers

Idempotency-Key

string

Lets you retry safely. Valar records a reservation under the combination of organization, API key, and Idempotency-Key, so sending the same value again hands back the stored response rather than running inference a second time. Values can be up to 255 characters. See Idempotent Requests for the complete rules.

Maximum string length: 255

Body

application/json

model

string

required

input

required

Accepts text, and image input (input_image) when you target a multimodal model. Valar does not yet accept audio, files, or item references.

Minimum string length: 1

max_output_tokens

integer | null

Required range: x >= 1

temperature

number | null

Required range: 0 <= x <= 2

top_p

number | null

Required range: 0 <= x <= 1

prompt_cache_key

string

An optional hint Valar uses to keep prompt-prefix caches local. Requests sharing a key are steered toward the same place so you hit the cache more often.

metadata

object

Optional string-valued metadata. Use completion_window to influence scheduling, and completion_webhook together with webhook_token to wire up a webhook that fires on completion.
