GrowthBook is an open source feature flagging and experimentation platform with a warehouse-native statistics engine.
GrowthBook publishes 51 API contracts indexed on the APIs.io network, including AnalyticsExplorations API, Archetypes API, Attributes API, and 48 more. Tagged areas include Feature Flags, Experimentation, Open Source, A/B Testing, and Analytics.
The GrowthBook catalog on APIs.io includes 1 Spectral governance ruleset.
GrowthBook’s developer surface includes authentication, documentation, engineering blog, and 12 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/.
Show this score on your site.
It updates itself when the score changes. Paste this where you link to your API docs:

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) Ask about this →
Stable Error Semantics+8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes Ask about this →
Typed Event Surface+6 pts — AsyncAPI document, OR webhooks/callbacks objects in the as-published OpenAPI, OR common[].type includes Webhooks Ask about this →
Pagination+5 pts — share of collection GETs (an array, or one wrapped in data/items/results ...) that declare a page/limit/offset/cursor parameter, a Link header or a next/cursor field; na with no collection GETs Ask about this →
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.
Not sure how this applies to your stack? Ask about any one item. Kin Lane reads every question, looks at your profile and your situation, and replies with what a fix would take — scoped to that one area, priced up front, yours whether you ship it or not. Ask a question →
The Kin Score Market layer reads a provider inside its market:
its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted:
not part of the Kin Score or agent readiness.
Registered MCP server and declares compatibility are report only — not weighted.
Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.

description: '**Beta** — these endpoints are new and may change in backwards-incompatible ways.
Reusable, typed, inheritable JSON objects referenced from feature flag values as `@config:key`. A config carries a field
`schema` (with TypeScript/JSON Schema import-export) and a lineage `parent`. Inheritance is expressed via `parent`, never
an in-value `@config:` entry. Values layer as a **deep, targeted patch**: a child (or a config-backed feature value) restates
only the leaves it changes and inherits the rest — unlike a constant''s `$extends`, whose own keys replace wholesale.
Schema fields colliding with a published ancestor''s key follow ''base wins'': identical re-declarations are stripped
with a warning, differing ones are rejected.'

Reusable named values referenced from feature flag values as `@const:key` and resolved into the SDK payload at build time.
String constants are interpolated via `{{ @const:key }}`; JSON (object) constants are composed via an `$extends` array.
A constant''s own keys **replace** what its `$extends` bases provide, wholesale — constants are atomic building blocks.
(Config and feature values compose as deep, targeted patches instead.)'
