Google Tag Manager

Google Tag Manager is a tag management system that lets teams deploy and update measurement codes and related code fragments — collectively known as tags — on a website, mobile app, or server-side container without editing site code on every change. The Tag Manager API v2 exposes that configuration programmatically: accounts, containers, workspaces, tags, triggers, variables, container versions, and user permissions, across web, iOS, Android, AMP, and server-side usage contexts. Changes are staged in a workspace, frozen into an immutable container version, and then published to live traffic, with fingerprint-based optimistic concurrency guarding every write. Access is OAuth 2.0 only, with seven granular scopes separating read, edit, publish, and user-management rights.

Google Tag Manager publishes 9 API contracts indexed on the APIs.io network, including Accounts API, Containers API, Triggers API, and 6 more. Tagged areas include Analytics, Conversion Tracking, Marketing, Tag Management, and Tracking.

The Google Tag Manager catalog on APIs.io includes 2 JSON-LD contexts and 3 Spectral governance rulesets.

Google Tag Manager’s developer surface includes sandbox, pricing, API reference, changelog, authentication, developer portal, getting-started guide, and 67 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
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document
Typed Event Surface +6 pts — AsyncAPI document, OR webhooks/callbacks objects in the as-published OpenAPI, OR common[].type includes Webhooks
Documented Reversibility +6 pts — a reversal operation in the contract, graded up when a window is documented too

5 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.
