    tools/list returned 7 tools.

  • Pass
    Current protocol

    Negotiated 2025-06-18. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 57 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

    Every tool description is at least 20 characters.

    Website matches publisher

    The website host matches the reverse-domain namespace.

  • Fail
    Source repo linked

    No repository URL is on file.

  • Not measured
    Repo owner matches

    This namespace is not an io.github login, so the owner comparison does not apply.

Capabilities

Tools 7

best_service_for_task

Use when a router agent must pick which paid x402 service to send a task to: send the task in plain words, get the top listing from P0's snapshot of listed x402 services plus up to 4 alternatives. Returns the paid x402 request for your input (GET /route, $0.01 per call; schema linked). Call that URL with an x402 or MPP client to get the data. Bad input is refused before any charge. Paid pick of one service for one task; for free browsing and comparing use search_x402_services. With an access key (Authorization: Bearer p0k_..., buy at https://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/keys/buy?usd=5) the tool pays the call itself, returns the data and deducts the price. First call each day returns the data itself, free; later calls return the paid request.

Discovered
economy

Use when you need the agent economy beyond x402 in one call: per protocol. Returns the paid x402 request for your input (GET /economy, $0.003 per call; schema linked). Call that URL with an x402 or MPP client to get the data. Bad input is refused before any charge. With an access key (Authorization: Bearer p0k_..., buy at https://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/keys/buy?usd=5) the tool pays the call itself, returns the data and deducts the price. First call each day returns the data itself, free; later calls return the paid request.

Discovered
economy_protocols

Use when you need one agent-economy protocol in detail: every normalised row (per chain or rail, all-time and 30-day windows) for x402, Tempo MPP, Virtuals ACP, Olas, Masumi, ERC-8004. Returns the paid x402 request for your input (GET /economy/protocols, $0.002 per call; schema linked). Call that URL with an x402 or MPP client to get the data. Bad input is refused before any charge. With an access key (Authorization: Bearer p0k_..., buy at https://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/keys/buy?usd=5) the tool pays the call itself, returns the data and deducts the price. First call each day returns the data itself, free; later calls return the paid request.

Discovered
economy_search

Use when you need callable agent services for a capability across protocols: verified x402 sellers (Agenstry, Open 402, pay.sh; price, networks, evidence), MCP servers. Returns the paid x402 request for your input (GET /economy/search, $0.002 per call; schema linked). Call that URL with an x402 or MPP client to get the data. Bad input is refused before any charge. With an access key (Authorization: Bearer p0k_..., buy at https://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/keys/buy?usd=5) the tool pays the call itself, returns the data and deducts the price. First call each day returns the data itself, free; later calls return the paid request.

Discovered
list_paid_data_products

List the paid data products on this host (wallet balances and EVM chain reads, payment check, sanctions, payee and counterparty checks, risk labels, LEI and bank lookups, SEC filings and contract awards, vulnerability, package and IP checks, domain and site checks, email and URL checks, interest rates, ECB euro exchange rates, news, weather and hazards, Wikipedia knowledge search, the agent-economy index across protocols, time, random and utilities, agent memory, batch variants and the /buy/* service orders): route, price per call in USD, parameters and an example request URL. The data itself is paid per call over x402 or MPP at that URL. Lists THIS host's own paid tools only; to find third-party APIs use search_x402_services.

Discovered
search_x402_services

Search verified x402 sellers by capability (from Agenstry, Open 402, pay.sh, the Official MCP Registry, apis.io and other public registries; each with price, networks and evidence of a live 402 or manifest). Free tier returns the top 5; full results are the paid /search endpoint (x402 or MPP) on this host. Calls and paying wallets are P0's own on-chain transfer counts, null where not measured. Not for picking one service for a concrete task (use best_service_for_task), for market-wide totals (use x402_market_stats) or for this host's own products (use list_paid_data_products).

Discovered
x402_market_stats

Statistics of the verified x402 seller set (sellers by source and evidence, median declared price; not the whole market) and 30-day x402 market totals from x402stats (CC BY 4.0, attributed in the answer). No parameters. Market-wide totals only, no per-service rows; for individual services use search_x402_services; for this host's own tools use list_paid_data_products.
