summary: Price a model call before running it, without running it.
description: 'Returns a pre-flight estimate, in US dollars, of what running this body on this model will cost, priced at Comfy''s standard list price (a model billed the cost its vendor reports is estimated from the vendor''s published price list instead). It does not reflect contract or customer-specific rates: a workspace with negotiated pricing is quoted the list price and charged its contract rate, and `source: exact` then means exact at list price, not that workspace''s charge. It is an estimate, not the final charge: the settled charge in your workspace''s usage and billing records is what you pay. The body is validated against the model''s input schema first, as a default run (no `strict_mode`, no `reject_unknown_fields`) validates it, so a body that fails the model''s schema is the same `422` here as on the run; nothing is dispatched to a provider and nothing is charged. The answer is not a price lock: it is priced at the rates in force at `pricing_as_of`, and a run is charged at the rates in force when it is rated. If estimates are switched off for a deployment the route answers `403` with `error_type: not_enabled`; a model Router cannot run yet answers the same `403` with the run route''s own `detail`, so read `detail` to tell the two apart. For a request that names `model_provider`, or a multipart body Router sends to a sibling operation, this route can price a different body than the one dispatched and can still label that figure `exact`, and a caller cannot tell when a multipart body is sent to a sibling operation. So for those calls there is no accurate pre-flight quote, and `source` on this route''s answer does not describe the run, even when it reads `exact`. The `estimate` on the queued submit''s `201` is priced on the dispatched body, but it is not a pre-flight price: it arrives only after the run is admitted and queued, and that run is charged unless it is cancelled before dispatch.'

description: 'A pre-flight estimate of what this call will cost, in US dollars, priced before dispatch at Comfy''s standard list price, or — for a model billed the cost its vendor reports — from the vendor''s published price list. For that vendor-reported case, `source: exact` is returned only for a small opted-in set of models, and only when the published price list fully determines the figure (every price-driving field was stated, or left at a default that cannot change it); every other vendor-reported quote is `estimated`, including some the list would fully determine. Either way the run is still billed the amount the vendor reports after it completes, never the quoted figure verbatim.

The queued collect (`GET /v2/models/{provider}/{model}/requests/{request_id}`) of a run that ended `invalid_input` carries the same reason in this field on its first collect, which then deletes it from the request: a later collect normally answers the same `error_type` and `detail` without it, so read it from the first collect. That read sends neither header.'

Scope the header requirement to synchronous responses.

A queued collect can return upstream_detail without X-Comfy-Upstream-Status, but this description also says the field is present only when that header carries a provider status. A caller following that rule can discard the reason on the first collect, after which it is deleted. (raw.githubusercontent.com)

Clarify the exception in the canonical contract and resync the spec. As per coding guidelines, vendored specs are “synced one-way” and must not be hand-edited.

Review comment at @spec/router-openapi.yaml at line 604:
Update the canonical contract description for upstream_detail to limit the
X-Comfy-Upstream-Status condition to synchronous responses and clarify that a
queued collect may include the reason without that header on its first collect.
Regenerate and resync the OpenAPI spec from its source of truth so callers know
to read the reason before it is deleted.

description: 'Which input or output a content-policy refusal was about, as a Router-level closed vocabulary: `input`, `output`, `input_text`, `input_image`, `input_video`, `input_audio`, `output_text`, `output_image`, `output_video`, `output_audio`. The bare `input` / `output` values name the side when the provider did not name a modality. Present only when `error_type` is `content_policy_violation` and the provider named the refused subject with a machine-readable code; absent otherwise. Never provider text. Named today for BytePlus, Runway, BFL, Gemini, Veo, Vertex, xAI and Wan refusals, and for the MiniMax Router''s Nano Banana legs'' Gemini refusals; a provider whose refusal does not say which side it was about leaves it absent. It mirrors the `X-Comfy-Refusal-Subject` header.'
