Models

GET /v1/models

Returns all available models with pricing and metadata.

Authentication is optional. With an API key, prices are shown in your organization’s billing currency; without one, prices are shown in USD. Requests without a key are rate-limited to 600 per minute per IP, one budget shared by every catalog endpoint callable without a key, including GET /v1/videos/models.

Example

curl https://api.aiand.com/v1/models

With an API key:

curl https://api.aiand.com/v1/models \
  -H "Authorization: Bearer sk-your-api-key"

Model name resolution

The model parameter you send on an inference request (/v1/chat/completions, /v1/completions, /v1/responses, /v1/messages) must be an exact model id from GET /v1/models. Matching is case-insensitive, but partial names are not accepted: a model family without its version returns a 404 with error code model_not_found rather than guessing a version. Use GET /v1/models as the source of valid names.

Usage is always recorded and billed against the model’s canonical id, regardless of the casing you sent.

Cost calculation

cost = (input_tokens / 1_000_000 * input_per_1m) + (output_tokens / 1_000_000 * output_per_1m)

Credits are deducted after each successful request. Failed requests (4xx/5xx) are not billed.
