Regulatory Posture applies to this provider. Its tags matched the Telecommunications 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 could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% 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
Typed Event Surface +6 pts — AsyncAPI document, OR webhooks/callbacks objects in the as-published OpenAPI, OR common[].type includes Webhooks
Documented Reversibility +6 pts — a reversal operation in the contract, graded up when a window is documented too
Agentic Commerce Well-Known Document +5 pts — a parsing /.well-known/ucp.json or acp.json declaring a version and at least one service — `self` when its endpoints are on the provider's own domain, `platform` when they are on a vendor's

4 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.

  name: Instasent OAuth API
  description: 'OAuth 2.1 endpoints — Dynamic Client Registration, the token endpoint, and the

    discovery metadata that lets a client find them. They exist so a third-party

    application (or an MCP client) can obtain a Product API token **in the user''s

    name**, instead of asking them to create one in the dashboard and paste it. All

    of them are anonymous by design: a client has no credential until it completes

    the flow.


    These endpoints live at the **API host root**, outside the `/v1` product prefix

    (`https://api.instasent.com/oauth/token`, not

    `https://api.instasent.com/v1/oauth/token`), which is why each one declares its

    own server.


    The **authorization endpoint is part of this API too**, at

    `GET /oauth/authorize`. Consent still needs a logged-in user in front of a screen,

    which only the dashboard can provide, so that endpoint answers `302` and sends the

    browser to the dashboard''s consent screen with the query string untouched. It is

    served here, on the issuer''s own origin, so the whole authorization server is

    advertised on a single origin: clients that require the authorization endpoint to

    match the issuer work without special handling. Open it in a browser, then bring

    the resulting `code` back to `POST /oauth/token`.'
