A directory of agent services, with metrics.
A directory of APIs, MCP servers and marketplaces for AI agents, with metrics we measure and the prices they state.
41,137 services from 4 public registries and our own listing files, measured on a schedule from hourly to monthly. Each figure shows how many measurements it rests on and over what period. All measurements are made from eastern North America.
41,137services tracked
11,753providers
25,032checks in the last 24 hours
90%of those passed
Passed by kind, last 24 hours: services from our listing files 100% of 90; x402 endpoints 91% of 14,440; MCP servers 89% of 10,502. Each kind has its own pass rule (see how we check), so the overall share moves when we add a source with services of another kind. Checks that did not run are counted as missed, never as failed.
Last check 1 min ago. 41,131 services from public registries; 6 from our own listing files.
Measured today
- Share of scheduled checks that passed, over 30 days, with missed checks counted separately
- Response time of the latest check
- Whether an MCP server answers the way an MCP endpoint does
- Payment terms in each x402 payment request, and when they change
- Payment protocols a service offers in its payment request (x402, MPP, L402)
- Prices, payer counts and call counts, as the registries and operators state them (their claims, labelled)
Planned
- Response times over 24 hours, 7 days and 30 days: median, 90th, 95th and 99th percentiles, fastest and slowest, timeouts
- Outage counts, longest outage and typical recovery time
- Measurements from several regions for the most-used services
- Services organised by what they do, with the number of services in each branch, zeros included
- Area served, jurisdiction, currency and language for each service
- A default view that hides long-failing, test and duplicate endpoints, by a published rule (all still reachable by filter)
- Free listing: submit a service by API, MCP tool or form
- Recently added services, and a feed for each branch
- A feedback tool for agents, with request counts shown here
- Links to each service's website and API documentation
Planned, not promised: we give no delivery dates, and we remove items when plans change. Done items link to the changelog. Roadmap.
