GET /v1/models response for exact IDs with mode: live. A catalog entry or successful connection check does not enable a model.
Request lifecycle
1
Authenticate
The
Authorization: Bearer key is hashed and matched against active keys. Revoked keys fail immediately with 401 unauthorized.2
Rate limit
The key’s IP allowlist is checked, then the per-minute and concurrency limits: by default 120 calls per minute and 5 concurrent calls for the whole workspace. See Rate limits.
3
Resolve the model
The
model ID must be active in the key’s workspace, otherwise the request fails with 404 model_unavailable.4
Check availability
The model must currently be available for live calls, otherwise
503 channel_unavailable.5
Meter and record
A live call first reserves a conservative wallet/key budget in an
atomic transaction, before the call is dispatched once. Valid final usage settles
frozen rates and releases the unused hold. An ambiguous result after dispatch
remains pending reconciliation; there is no automatic paid retry or refund.
An insufficient live
reservation budget returns
402 before contacting the provider.Live limits
The example below is GPT 5.4 Mini. Most integrated text models allow up to 128,000 output tokens and default to 32,000 (Gemini 3.1 Pro Preview and Gemini 3.6 Flash: at most 65,536); DeepSeek V4 Pro, GLM 5.3 and Kimi K3 default to and allow at most 4,096; GPT 5.4 Mini defaults to 64 and allows at most 256. Check SSE and reasoning support per model. Automatic paid failover is not supported.gpt-5.4-mini supports text/system messages and JSON/SSE responses, with default
64 and maximum 256 output tokens. Reasoning is explicitly none. Function tools, JSON object/schema and stateless Responses HTTP/SSE are enabled for GPT 5.4 Mini; strict tools, vision and sampling remain disabled. Physical joint context
is 400,000 tokens. The gateway reserves a request-sized input bound, capped by the
input ceiling, independently of output. The maximum hold depends on current workspace prices and is not the final
fee. Model details label this provider-context-ceiling and say the provider checks
context fit. Read Usage and billing before enabling
automatic retries in your application.

The API hostname serves only
/v1/* and /health. Every other path returns 404.
Automatic paid retries and failover are not enabled. New models require capability and billing verification before workspace activation.
