• get_listing_intel

  Audit your own x402 listings against the live Bazaar catalogue. Authenticity scoring separates genuine demand from self-traffic (the catalogue's highest-volume listings are frequently a merchant calling itself), listing-health diagnostics explain why a listing takes no paid calls, and price-band guidance is drawn from what measurably sells. Includes your revenue percentile across all indexed merchants. [PAID: $1 USDC per call via x402 on Base. First call without payment_signature returns the payment requirements.]

  Parameters:

  • tag — string — Optional keyword to scope pricing guidance to comparable services.

• get_market_history

This returns per-day ecosystem GMV, merchant and listing counts, price-band distribution and median/P90 pricing; per-merchant lifecycle with first-seen, last-seen and departure; every observed price change with date and magnitude; and the biggest movers ranked by change in unique paying wallets rather than call count, because call volume is trivially inflated by a merchant calling its own endpoint. The free current-snapshot view is at /state-of-x402. [PAID: $25 USDC per call via x402 on Base. First call without payment_signature returns the payment requirements.]

  Parameters:

  • days — string — Limit to the most recent N daily snapshots. Omit for the full archive. Max 400.

  • payment_signature — string — Optional x402 payment token. Call the tool WITHOUT this first to receive payment requirements (price, payTo, asset, nonce rules), sign the exact-scheme EIP-712 USDC authorization with your wallet, then retry with this field set to the base64 token.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• check_listing_health

  FREE x402 merchant listing health report (3/day/IP). Pass your merchant domain or payTo address and get: per-listing serviceName/tags/icon checks, 30-day call and payer counts, revenue proxy, market rank among all Bazaar domains, and a prioritized fix list. The free tier of the paid trends/competitors/audit suite. [FREE]

  Parameters:

  • payTo — string — Merchant payTo address (0x...). Provide this or domain.
  • domain — string — Merchant domain to analyze (e.g. api.example.com). Provide this or payTo.
