Read-only MCP server for querying OkkMax measurements of AI API relay services, including model availability, observed prices, 24-hour uptime, latency, and model- and group-level purity evidence. No sign-in or API key is required.
Signed declarations of HTTP API exchanges for agent handoffs. Free preparation and verification; receipt issuance costs 0.002 USDC via x402 on Base. Start and connect: https://datoka.dev/api. Signatures attest declared data, not independent truth.
API documentation drifts away from the running service, so consumers integrate against a contract nobody keeps. Routebase keeps API design, testing, mocking and documentation on one living source of truth, and this MCP server exposes that workspace to AI agents. Agents can design endpoints, write and run test suites, manage mock servers and publish documentation, always under the permissions of the connected Routebase account.
Live health leaderboard of x402 paid endpoints, plus an MCP server readiness check
Read-only MCP server checks and quote verification, free and keyless; results signed and publicly lo
Verified, reproduced behavior of public HTTP APIs: spec gaps, errors, pagination, auth.
Audits a sample of HTTP request URLs against explicit, documented cache-key standardization rules...
Signed deterministic checks for supplied JSON invoices, OpenAPI API contracts and JSON events.
Independent checks of paid x402 data sellers and of AI-agent access to shopping and travel sites
Experimental MCP server for current empirical verification of explicit public HTTPS endpoint claims.
Meaning of HTTP 406.
If-Match etag list count, value discarded
Meaning of HTTP 415.
Ephemeral HTTPS inbox for bots: mint URL, capture POSTs, list JSON. TEST. https://inbox.kymac.co
AI-native mock API server with MCP. Create REST/SOAP mocks from Claude, Cursor, or Windsurf.
Search millions of x402 APIs for data, finance, validation, security, inventory, sync and automation
Check an MCP endpoint resolves: liveness, live tool list, schema drift. Free.
Breaking changes of third-party APIs: check your code's API calls before they break.
Search a catalog of tools and APIs, inspect endpoint schemas and prices, and run endpoints from an MCP client. Runs can use a prepaid workspace balance. The hosted server supports OAuth and bearer authentication.
Send one HTTP request, or one per row of a dataset, CSV or Google Sheet, and get the response back
Gibs is a multi-regulation compliance API for developers building applications that need to reason about EU regulations. Classify AI systems under the EU AI Act, ask compliance questions about GDPR and DORA, and get source-cited answers with article-level traceability — all in one API call.
The Grafbase MCP server sits in front of a GraphQL API and exposes an MCP protocol-compliant interface that allows AI agents and LLMs to explore and query GraphQL APIs using natural language. It provides tools to search schemas, introspect types and fields, and execute GraphQL queries while minimizing context bloat by returning only relevant schema subsets, with built-in support for authentication, authorization, and configurable access control.
