Mirage

Mirage is an AI research company headquartered in New York City that builds Captions, an AI video editor and generator used by more than 20 million creators, small businesses, and enterprises worldwide. The Mirage Video API exposes the company's state-of-the-art video models over a simple HTTP interface: generate expressive human video from an image and audio (Mirage Video 1), apply styled captions to an existing video, synthesize speech with text-to-speech voices, and render meta text overlays. It is an asynchronous submit-and-poll REST API authenticated with an x-api-key header and priced by usage (per minute of captioning, per second of generated video).

Mirage publishes 7 API contracts indexed on the APIs.io network, including Audio API, Health API, Internal API, and 4 more. Tagged areas include Company, Artificial Intelligence, Video, Video Generation, and Captions.

The Mirage catalog on APIs.io includes 1 event-driven AsyncAPI specification and 1 Spectral governance ruleset.

Mirage’s developer surface includes documentation, API reference, getting-started guide, authentication, pricing, signup flow, support, and 22 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the AI & Biometrics regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):

MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Rate-Limit Signaling +7 pts — OpenAPI responses document X-RateLimit-* / RateLimit headers (verified), else a rate_limits artifact or RateLimits link (documented)
Request/Response Examples +7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document

7 more unmet checks in the Agent Readiness table above.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it.
