api record

Tools for marketplaceforaiagents.com, a marketplace of 51 x402-gated APIs (38 single-engine endpoints plus 13 multi-step intent chains such as serp-stack, news-brief, video-digest) (web search, news, images, commerce, maps, travel, jobs, academic, app stores, video) that autonomous agents pay for per call in USDC on Base at $0.005 per engine call ($0.005 x steps for intent chains), with 3 free calls per agent identity. Use `list_apis` (with optional query/category filters) to find an endpoint, `get_api_spec` for parameters and response shape, `get_payment_requirements` for the x402 payload to sign (base mainnet or the base-sepolia sandbox), `get_agent_entrypoints` for machine-readable manifests and Markdown page twins, and `get_integration_guide` for long-form docs. All data is public; the paid API calls themselves happen over plain HTTP against the listed endpoints.

_ used through this hub 30 days

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • get_agent_entrypoints open 12h ago

    Return every machine-readable entrypoint of the marketplace (x402 manifest, OpenAPI, JSON catalog, llms.txt, Markdown page twins) so an agent never has to parse HTML.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
