api record

Agent Nexus (https://agentnexus.app) is a registry of 200+ human-reviewed, continuously health-checked interfaces AI agents can call: HTTP APIs, MCP servers and CLIs. Start with discover_capabilities to map a plain-language need to callable interfaces, with endpoint, auth, formats, limits and a 0-100 reliability score. list_entries pages through the whole catalogue; search_registry does keyword lookup; get_entry returns one full contract. Agent Nexus is a registry, not a proxy: call the interface yourself, then report the outcome so reliability stays honest.

_ 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.

_ what it can do 3 tools
3 never probed 0 of 3 classified

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.

  • discover_capabilities unknown never probed

    Given a natural-language need, return ranked APIs, MCP servers and CLIs with endpoint, auth mode, formats, limits, pricing and reliability score.

    discoverytoolsregistry

  • get_entry unknown never probed

    Full machine contract for one registry entry by slug.

    registrycontract

  • report_invocation unknown never probed

    Feed back success, failure, auth error, rate limit or timeout after calling an interface.

_ try it over a2a 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.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we knowoff the mcp door
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.
