Guild.ai

Guild.ai is a control plane for AI agents that lets engineering teams build, deploy, govern, and share agents in production. Agents are authored in TypeScript with the @guildai/agents-sdk (alongside Guild Native and Goose recipe agent types) and run in a governed, sandboxed runtime that mediates all external tool access and enforces least-privilege scoped credentials, with workspaces, versioning, audit logs, and real-time usage and cost tracking. Guild is model-agnostic across OpenAI, Anthropic, and Google, ships a first-party CLI that also runs an MCP server, exposes a Guildcode REST API plus per-trigger API keys for programmatic invocation, offers 40+ integrations (GitHub, Slack, Jira, Linear, Notion, Google Cloud, and more), and provides an Agent Hub for discovering, forking, and publishing agents. Backed by GV, NFX, and Khosla Ventures.

Guild.ai is listed with 1 API on the APIs.io network. Tagged areas include Company, Artificial Intelligence, AI Agents, Agent Control Plane, and Agent Runtime.

Guild.ai’s developer surface includes documentation, API reference, getting-started guide, engineering blog, support, pricing, signup flow, and 13 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 could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% 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):

Machine-Readable Contract +18 pts — api_specs includes an OpenAPI document
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)
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)

11 more unmet checks in the Agent Readiness table above.

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

Contract Quality scores 0.0 — up to +25.0 composite points
Access Clarity scores 31.6 — up to +13.7 composite points
Operational Transparency scores 0.0 — up to +13.0 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/guildai/apis.yml: open an issue on github.com/api-evangelist/guildai to ask a question or point us at an artifact you publish.
