- target: $.info
  description: Add a machine-readable support contact. The published contract names no contact, so a consumer that
    hits a defect has no address inside the artifact.
  update:
    contact:
      name: Everbridge Developer Hub
      url: https://developers.everbridge.net/home/discuss
- target: $.info
  description: Declare the contract's licence. Everbridge publishes these documents on a public developer hub under
    its standard terms; stating it removes the ambiguity for downstream tooling.

  description: Point the contract at the guides that carry the runtime semantics it does not encode — authentication
    grants, throttling tiers and the error table.

    externalDocs:
      description: Everbridge API Developer Hub — Getting Started Guide
      url: https://developers.everbridge.net/home/docs/ebs-gs-guide
- target: $.paths.*.*.responses
  description: Everbridge documents Bronze/Silver/Gold throttling and returns 429 on exhaustion, but this contract
    declares no 429 response, so a generated client has no branch for it. Declare 429 on every operation.
  x-source: https://developers.everbridge.net/home/docs/ebs-gs-guide-throttling-limits
- target: $.paths.*.*.responses.429.headers
  description: Everbridge publishes no rate-limit response headers. Adding RateLimit-Limit, RateLimit-Remaining,
    RateLimit-Reset and Retry-After would give an agent a runtime budget signal instead of forcing it to infer one
    from a bare 429.
  x-status: recommendation — Everbridge does not currently emit these
- target: $.paths.*.post.parameters
  description: No idempotency mechanism exists anywhere in the Everbridge surface. Launch Mass Notification and
    Launch Incident have irreversible real-world side effects; an Idempotency-Key request header would let a client
    retry a timed-out launch safely.
  x-status: recommendation — Everbridge does not currently support this
