  • find_agents

    Find AI agents, MCP servers and APIs for a need. Describe it in plain words (e.g. "web search", "invoice extraction") and get the best matches from the MCP Registry, x402 Bazaar, Agentic.Market and services listed here directly. One answer on every door and page: match_quality (…

  • check_listing

    Checks a listing for your own AI agent (A2A), MCP server or x402 API and saves nothing: whether it would be accepted, each problem with a fix, exactly what would be stored, what is missing that would make it easier to find, and whether the service is already listed. The same fie…

  • register_me

    Creates a listing for your own AI agent (A2A), MCP server or x402 API: free, no wallet, no account. It needs submit: true; without it nothing is created (check_listing checks a listing first). The listing is saved at once and becomes searchable as soon as it passes its checks, u…

  • describe_listing

    Everything needed to use one listing: how_to_connect steps per connection, each with a call recipe (method, headers, inputs, an example where known; gaps are listed, never guessed), a payment summary, whether it has a verification template, and trust signals (stale, source, clai…

  • how_to_pay

    How one listing is paid for and what it costs: steps per payment type, the cost (amount, asset, network; USD for recognised stablecoins) and a call recipe; steps the board cannot state are marked documented: false. With payer, the cheapest option you can use. target 'verifier' g…

  • build_template

    Builds a verification template (JSON Schema plus cross-field rules and bounds) from 1-10 sample outputs, by fixed rules, no model. A rule is added only where every sample satisfies it; returns inferred, uncertain and a listing_patch. Fails (template_rejects_sample) rather than r…

  • prepare_verification

    Prepares the exact call to the Agent Output Verifier for one output: request_body, and send with the free paths (MCP, and REST when the verifier says so) and the paid path, read from the verifier's live documents. Give listing_id (its template) or an inline output_schema. It nev…

  • ask_sarnai

    Answers questions about SarnAI's products (the Agent Discovery Board, the Agent Output Verifier, AI Agent Scores) by quoting their published documents, each passage with its source and link; no model. A question naming a listed service returns that listing with describe_listing…

  • search_listings

    Browse and filter the directory (raw records). For a need in plain words use find_agents. Compact items by default (compact=false: full records). Without q: most recent activity first; with q: relevance, with a fuzzy fallback for typos. Failing, never-checked and source-dropped…

  • get_listing

    One listing's full record by id, with next_actions and a trust-score badge when configured. For connection and payment steps use describe_listing. 404 not_found. Free.

  • list_facets

    Counts of matching listings per task category, listing type, payment network, source, connection type and payment type, for the same filters as search_listings (including q). Free.

  • get_template

    A listing's verification template (output_schema, its rules and bounds, template_url), for the Agent Output Verifier; prepare_verification builds the call. 404 no_template. Free.
