openapi: 3.2.0
info:
  title: Crevio API V1 SMS messages API
  version: 1.0.0
  description: 'API for the Crevio creator platform — a multi-tenant SaaS for digital product sales.

    Uses snake_case keys following Stripe conventions. All resource IDs are string IDs (e.g., "prod_abc123").


    Authentication is a bearer token: `Authorization: Bearer $CREVIO_API_KEY`.

    List endpoints are cursor-paginated with `limit` and `starting_after`.

    Writes accept an `Idempotency-Key` header and are safe to retry.


    Every response carries IETF RateLimit headers (`RateLimit`, `RateLimit-Policy`) so a client can

    self-throttle, and `Retry-After` on a 429. The quota is 600 requests per minute per credential.


    The API is versioned in the URL path (`/v1`). Nothing is removed without in-band warning: a

    deprecated operation is marked `"deprecated": true` here and serves `Deprecation` (RFC 9745),

    `Sunset` (RFC 8594) and `Link; rel="deprecation"` headers for at least six months before it

    stops answering. See https://crevio.co/docs/developer/guides/versioning.'
