Sonarly

Sonarly is an AI production-reliability platform (Y Combinator W2026, Paris) that turns noisy production alerts into clear, deduplicated bug reports and ships ready-to-merge fix pull requests. It connects to a team's code (GitHub/GitLab) and their error and observability stack — Sentry, Datadog, Grafana, New Relic, SigNoz, CloudWatch, GCP, and many more — then triages every alert to remove noise and duplicates, investigates logs, traces and metrics to find the root cause, and generates a fix PR or alerting-rule recommendation. Sonarly exposes a read-only public REST API (v1) for pulling bugs, incidents and analysis runs into custom dashboards, signed outbound webhooks for live events, and a device-code style setup-session API that lets a coding agent (Claude Code, Cursor) onboard a tenant end-to-end. Onboarding is fully agent-native and documented at sonarly.com/llms.txt.

Sonarly publishes 3 API contracts indexed on the APIs.io network: Bugs API, Incidents API, and Setup API. Tagged areas include Company, Reliability, Observability, Monitoring, and Bug Detection.

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

Sonarly’s developer surface includes engineering blog, documentation, API reference, authentication, pricing, signup flow, and 16 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
Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
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

7 more unmet checks in the Agent Readiness table above.

Kin Score — facets with the most composite points still available (weight × headroom):

Contract Quality scores 21.3 — up to +19.7 composite points
Developer Ergonomics scores 16.1 — up to +16.8 composite points

Each check links to what satisfies it. Publish the artifact, or tell us where it already lives, and the score moves on the next scoring run.

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/sonarly/apis.yml: open an issue on github.com/api-evangelist/sonarly to ask a question or point us at an artifact you publish.
