Google Cloud Datastore

Google Cloud Datastore is a fully managed, schemaless, highly scalable NoSQL document database for web and mobile applications, originally based on Google's Bigtable / Megastore stack. The service has since been rebranded as Firestore in Datastore mode, which preserves the Datastore API and data model while running on Firestore's storage layer for strong consistency and higher throughput. The Cloud Datastore REST API provides entity lookups, queries (including GQL), transactions, and project operations against datastore.googleapis.com, authenticated with Google OAuth 2.0 / service-account credentials.

Google Cloud Datastore publishes 3 API contracts indexed on the APIs.io network, including Projects API, and 2 more. Tagged areas include NoSQL, Database, Document Database, Google Cloud, and Firestore.

The Google Cloud Datastore catalog on APIs.io includes 1 Spectral governance ruleset.

Google Cloud Datastore’s developer surface includes authentication, documentation, pricing, signup flow, developer console, and 8 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)
Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes
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)
Request/Response Examples +7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link

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