GoatCounter

GoatCounter is open-source, privacy-friendly web analytics from Martin Tournoij, offered both as a free donation-supported hosted service at goatcounter.com and as a self-hostable Go binary backed by SQLite or PostgreSQL. It tracks pageviews without cookies or persistent personal identifiers. The unversioned JSON API, prefixed /api/v0 and served from each account's own subdomain, covers counting pageviews and events from a backend, reading dashboard statistics (totals, per-path hits, referrals, browser/system/location breakdowns), running asynchronous CSV and JSON exports with an incremental hit-ID cursor, and managing sites and users. Authentication is a per-site API key sent as an HTTP bearer token, and the provider publishes its own OpenAPI 2.0 contract at https://www.goatcounter.com/api.json.

GoatCounter publishes 9 API contracts indexed on the APIs.io network, including Exports API, Pageviews API, Paths API, and 6 more. Tagged areas include Analytics, Page Views, Privacy, Statistics, and Web Analytics.

The GoatCounter catalog on APIs.io includes 1 Spectral governance ruleset.

GoatCounter’s developer surface includes authentication, documentation, signup flow, API reference, getting-started guide, support, pricing, and 28 more developer resources.

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):

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
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)

8 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.
