Agent Readiness
A topic index covering the operational practices, signals, and patterns that make an API surface safely usable by autonomous AI agents rather than only by humans. Catalogs the specifications, identity layers, agent skill formats, and edge-layer signals that combine into a coherent agent-readiness posture, with a dimension model, JSON Schema, JSON-LD context, vocabulary, and example signal records for representative providers.

-
Model Context Protocol (MCP)
An open JSON-RPC protocol that lets AI agents talk to tools, resources, and prompts through a uniform server surface. MCP is the most direct expression of "an API designed for an agent" — every API surface that ships an MCP server scores h…
-
OpenAPI Specification
The dominant machine-readable contract for HTTP APIs. Presence of a public OpenAPI document — with examples, error schemas, security schemes, and rate-limit headers — is the single highest-leverage agent-readiness signal for a REST surface…
-
AsyncAPI Specification
Machine-readable contract for event-driven APIs (webhooks, message brokers, streaming). Agent-readiness for event surfaces depends on whether the provider ships an AsyncAPI document so agents can subscribe, dispatch, and validate events pr…
-
JSON Schema
The vocabulary that lets an agent validate request and response bodies against typed contracts. Published JSON Schemas (independent of, or embedded in, an OpenAPI) are a strong agent-readiness signal because they let agents self-correct pa…
-
Agent Skills
A community schema for publishing operational instructions an agent should follow when using a site or API. A provider that ships a `/skills/` directory with a skill index is signalling that it has thought about the agent workflow, not jus…
-
/.well-known/api-catalog (RFC 9727)
RFC 9727 defines `/.well-known/api-catalog` as the canonical machine entrypoint for discovering an organization's APIs, formatted as an RFC 9264 linkset. Presence of a catalog at this path is one of the cheapest, highest-impact agent-readi…
-
HTTP Message Signatures (RFC 9421)
A cryptographic signature scheme for HTTP messages, used by the emerging web-bot-auth profile to let agents authenticate themselves to origins. Provider support for verifying or surfacing RFC 9421 signatures is a forward-looking agent-read…
-
Web Bot Auth (draft)
IETF draft layering an "identified bot" profile on top of RFC 9421. A provider that publishes a directory of verified agent identities — or surfaces Web Bot Auth verdicts in its responses — is making agent traffic legible at the protocol l…
-
Content-Usage / AIPREF (IETF AIPREF WG)
The IETF AIPREF working group's effort to standardise machine-readable AI usage preferences (e.g. `Content-Usage: ai-input=y, ai-train=n`). A provider that publishes explicit AIPREF signals is making its consent posture legible to agents r…
-
Cloudflare Content Signals
Cloudflare's `Content-Signal` robots.txt directive, complementing the AIPREF drafts. Together they let an origin separate "crawl for search" from "use for AI input" from "use for AI training" — a concrete agent-readiness signal that the op…
-
APIs.json
The APIs.json format describes a provider's API portfolio in one machine-readable document. Publishing `/apis.json` (or `/apis.yml`) at the site root is the agent-readiness equivalent of a site identity card — it tells an agent who the ope…
-
OpenID Connect
Identity layer on top of OAuth 2.0. Agent-readiness for authenticated APIs depends on clear, discoverable OIDC metadata (`/.well-known/openid-configuration`) so agents can negotiate auth without reading prose.
-
Stripe API (reference provider)
Reference provider for the agent-readiness signal set. Stripe publishes its full OpenAPI, ships idempotency keys, surfaces rate-limit headers, has a consistent error envelope, and exposes a status page and changelog — close to a maximal ag…
-
GitHub REST + GraphQL API (reference provider)
Reference provider with arguably the most extensively-tooled developer surface on the web. Public OpenAPI, GraphQL schema, webhooks, conditional requests, explicit `X-RateLimit-*` headers, status page, and an MCP server — a near-complete a…
-
Twilio API (reference provider)
Reference provider with strong agent-readiness signals on the messaging side — published OpenAPI, idempotency on resource creation, structured error codes, signed webhooks, status page, and SDKs in every major language.
