This is not our API. This repository is an independent, third-party profile of a company's publicly available API surface, maintained by API Evangelist. API Evangelist does not operate, host, resell, or support this company's APIs, and is not affiliated with or endorsed by the company unless stated on the profile.
Where the information came from. Everything here is assembled from material a member of the public can reach with a browser and no credentials — the company's own website, developer portal and documentation, the specifications it publishes for public use (OpenAPI, AsyncAPI, JSON Schema,
apis.json,llms.txtand similar), its public repositories, and its public status, pricing and changelog pages. Nothing here is obtained by breaching a system, defeating an access control, or using credentials of any kind.The rating is an independent assessment. The Kin Score and Agent Readiness rating are independently calculated scores of a company's public API artifacts, produced by API Evangelist against a published rubric. They are not certifications, endorsements, security assessments, or audits, and they score published artifacts — not the quality, safety, or security of the software.
Corrections, re-scores, and removal are free. No partnership, contract, or purchase is required, and you do not need to justify the request.
- Something wrong? Open an issue on this repository, or email info@apievangelist.com.
- Published something new? Ask for a re-score and we will re-run the rating.
- Want the listing taken down? Say so and we will honor it. The profile is reduced to your company name, a factual description, and a link to your own site, and the company is recorded as unrated — never scored zero for having asked.
Response times. Acknowledgement within one business day; removal or restriction within two business days; corrections and re-scores within five business days.
On a security or compliance team? Email info@apievangelist.com with security in the subject line and you will get a person, not a form. We will tell you exactly which public URLs this profile was built from so your team can see the same surface we did, and we will take the listing down on request while you work through it.
Full detail: Where this data comes from
useapi.net is an experimental, unified REST API platform that fronts a set of consumer AI content-generation services — video, image, music, speech and face-swap models — behind one flat $15/month subscription and a single bearer-token API surface, so developers do not have to hold a separate developer account with each underlying provider.

Plus a cross-cutting account API at https://api.useapi.net/v2/account, and the retired Midjourney API (discontinued 2026-06-24) whose vendor-published OpenAPI is archived here.
useapi.net does not publish OpenAPI for its ten current APIs. It publishes first-party Postman v2.1 collections, referenced as service-desc entries from an RFC 9727 /.well-known/api-catalog linkset. Those collections are saved verbatim under postman/, and the OpenAPI 3.1 documents under openapi/ are faithful API Evangelist derivations of them — 298 operations, every path, parameter, body example and description carried over unchanged. The two useapi-midjourney-v*-openapi.yml files are the exception: they are vendor-published OpenAPI 3.0.2 harvested verbatim from SwaggerHub.
- One convention, then ten dialects. Bearer auth (
Authorization: Bearer user:<number>-<unique-string>) is the only platform-wide contract. The vendor states explicitly that identifier names, job lifecycle, response shapes, webhook payloads and status-code semantics all vary per API. - Bring your own account. Every generation API requires the caller to register their own account on the wrapped service (browser cookies or a session token), and an active subscription there. Costs land on that upstream account.
- No idempotency, anywhere. A retried generation POST creates a second job and spends credits. See
conventions/useapi-conventions.yml. - 7-day result retention, then
410 Gone. 596is a real, non-standard status meaning the linked upstream account's session is broken.- No status page, no SLA, no compliance program. The service is explicitly experimental. See
conformance/useapi-conformance.yml.
