CallRail

CallRail is a call tracking and conversation intelligence platform that attributes phone calls, texts, and form fills to marketing campaigns and applies AI-powered transcription, sentiment, and lead scoring to inbound conversations. The CallRail v3 API is a REST/JSON interface exposing accounts, companies, trackers, calls, texts, form submissions, and integrations. Authentication uses an account API key passed in the HTTP Authorization header against a base URL of https://api.callrail.com/v3/.

CallRail publishes 4 API contracts indexed on the APIs.io network, including Accounts API, Calls API, and 2 more. Tagged areas include Call Tracking, Conversation Intelligence, Marketing Attribution, Lead Tracking, and Telephony.

The CallRail catalog on APIs.io includes 1 event-driven AsyncAPI specification and 1 Spectral governance ruleset.

CallRail’s developer surface includes authentication, changelog, documentation, API reference, getting-started guide, pricing, signup flow, and 31 more developer resources.

Kin Score Kin Score How this is scored →
scored 2026-11-06 · rubric v0.27.0
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 applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.
The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% 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):
  • 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
  • Request/Response Examples +7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link
  • Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document
  • Delegated User Identity +6 pts — a served discovery document listing authorization_code in grant_types_supported (served), else an oauth2 authorizationCode flow or openIdConnect declared in an OpenAPI (documented)
  • Documented Reversibility +6 pts — a reversal operation in the contract, graded up when a window is documented too

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. This rating is computed from the provider profile at artifacts.apis.io/callrail/apis.yml: open an issue on github.com/api-evangelist/callrail to ask a question or point us at an artifact you publish.
