Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) 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
Rate-Limit Signaling +7 pts — OpenAPI responses document X-RateLimit-* / RateLimit headers (verified), else a rate_limits artifact or RateLimits link (documented)
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, OR (0.27) a live x402 payment challenge from _data/x402-adoption.json — `self` when its endpoints are on the provider's own domain, `platform` when they are on a vendor's

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.

  description: "Subscribe to events via outbound HTTPS webhooks — Pro plan and above.\n\n## Events emitted\n\nThe system currently\
    \ emits a single event:\n\n- **`alert.created`** — fired whenever an Alert is created in the\n  organization (triggered\
    \ by report processing and DNS change detection).\n\nOther event types (e.g. `report.received`, `domain.verified`) are\
    \ NOT\nemitted today. If your integration depends on them, treat them as out of\nscope until officially announced.\n\n\
    ## Delivery & signing\n\nEach delivery is a `POST` to the configured `url` with the JSON body\nmatching `WebhookEvent`\
    \ (see the schemas section) and the following\nheaders:\n\n| Header | Value |\n|---|---|\n| `Content-Type` | `application/json`\
    \ |\n| `User-Agent` | `DMARC-Examiner-Webhooks/1.0` |\n| `X-Webhook-Timestamp` | Unix epoch seconds when the request was\
    \ signed |\n| `X-Webhook-Signature` | `sha256=<hex>` — see signing below |\n\n### How the signature is computed\n\n```\n\
    signed_value = \"{X-Webhook-Timestamp}.{raw_request_body}\"\nsignature    = hex(HMAC-SHA256(webhook.secret, signed_value))\n\
    header       = \"sha256=\" + signature\n```\n\nThe signature covers BOTH the timestamp and the exact body bytes. The\n\
    shared `secret` (returned only at create time and re-fetched via\n`GET /webhooks`) **never travels on the wire** — only\
    \ the derived\nsignature does.\n\n### How to verify on your side\n\n1. Reject requests where `|now - X-Webhook-Timestamp|\
    \ > 5 minutes`\n   (rejects replays).\n2. Recompute the expected signature with your stored `secret` and the\n   raw body\
    \ you received.\n3. Compare with the value after `sha256=` using constant-time string\n   comparison (`crypto.timingSafeEqual`\
    \ in Node, `hmac.compare_digest`\n   in Python, `hash_equals` in PHP). **Do NOT use `==`.**\n4. Only after the signature\
    \ matches, trust the body and parse it as\n   `WebhookEvent`.\n\n## Retries\n\nFailed deliveries (network error or non-2xx\
    \ response) are retried twice\nwith delays of 30 s and 120 s. After 10 consecutive failures the webhook\nis auto-disabled\
    \ (`is_active` set to `false`) and no further deliveries\nare attempted until you re-enable it via `PUT /webhooks/{id}`.\n\
    \nSuccessful deliveries record the timestamp in `last_triggered_at`, the\nHTTP status in `last_status`, and reset `failure_count`\
    \ to `0`. The\n`POST /webhooks/{id}/test` endpoint does NOT touch any of those fields."
