Agent Bazaar tools (9)

write = sends, deletes, buys or posts
  • discover_agentsFree

    Search or list the A2A agent registry — other agents’ cards (name, skills, provider, protocol version), not Agent Bazaar’s own.

  • discover_providerFree

    List every resource published by a given provider host.

  • get_agentFree

    Fetch one registered agent's full card by slug or numeric id.

  • get_pricingFree

    Get just the price/accepts[] for a resource, without the full record — cheaper for an agent that only needs to decide whether it can afford something.

  • get_resourceFree

    Fetch one resource's full record by slug or numeric id: description, accepts[], output schema, quality signal, and agent-first metadata where the provider supplied it.

  • get_statsFree

    Catalog-wide totals: listings, resources, accepts, merchants, 30-day call volume, network/source breakdown.

  • list_resourcesFree

    Paginated listing of every indexed resource, ranked by 30-day call volume (or recency with sort="recent").

  • list_saylor_officialFree

    List verified Saylor Innovations x402 endpoints directly from the live Saylor manifest. Does not depend on the D1 catalog, so it keeps working during catalog quota exhaustion. Supports query, family, tag, network, asset, payTo, maxUsdPrice, limit and offset filters.

  • search_resourcesFree

    Search the marketplace by keyword and/or filters (network, asset, scheme, payTo, maxUsdPrice). Text queries rank by relevance; filter-only queries rank by 30-day call volume.

Agent Bazaar

by Saylor Innovations

An open, permissionless marketplace and discovery layer for AI agents — APIs, MCP tools, datasets, and x402-payable services that autonomous software can find, evaluate, and pay for per request. Repo/package name is still open-x402-bazaar for continuity; the product is Agent Bazaar.

Coinbase's own x402 Bazaar is excellent, but getting listed on it requires a verified Coinbase Developer Platform account, which in turn can require business/KYC verification for some account paths. That's a real barrier for a protocol whose whole point is permissionless, agent-to-agent commerce. This project is an attempt at an alternative: anyone with a valid x402 manifest can list here, with no account and no identity verification at all.

It's built to be wire-compatible with Coinbase's Bazaar discovery API, so any existing x402 client library that already knows how to query the CDP Bazaar can point at this instead with a config change, not a rewrite.

Live at: https://bazaar.saylorinnovations.com

Status

Live at bazaar.saylorinnovations.com, on Cloudflare Pages + D1. Submission, validation, storage, ranked discovery, resource/provider detail pages, and anti-spam basics are all working. The catalog is bootstrapped from a full mirror of Coinbase's public CDP Bazaar plus Saylor Innovations' own real endpoints — see below.

Seeded from Coinbase's Bazaar

Coinbase's discovery API itself requires no API key or account to read — only to list on it. So this project mirrors the whole public catalog (~15,600 resources across ~2,000 hosts, at last import) via scripts/import-cdp-bazaar.mjs, and layers permissionless listing on top:

  • Every mirrored listing is tagged source: 'cdp-mirror' internally.
  • Any owner can POST /submit their own manifest at any time — a self-submitted listing always overwrites the mirrored copy for that host and is tagged source: 'submitted'. The importer never touches a claimed host.
  • Mirrored resources carry Coinbase's own 30-day usage stats (calls30d, uniquePayers30d, lastCalledAt) as a quality field on each resource — a trust signal that matters more here than on a KYC'd catalog, since anyone can list anything.

Re-run the mirror periodically to pick up new resources Coinbase has indexed (safe to re-run — see script header):

npm run seed:cdp-bazaar          # generates + applies against local D1
npm run seed:cdp-bazaar:remote   # generates + applies against production D1

Saylor Innovations' own listings

scripts/import-saylor-official.mjs lists Saylor Innovations' real, live x402 endpoints (research/security/data utilities plus Solana on-chain intelligence, all served from saylorinnovations.com) as verified (source: 'submitted') resources — the same trust tier a self-submission gets, seeded directly since Saylor Innovations operates this bazaar. Nothing here is fabricated: pricing, descriptions and accepts[] come from the live /api/services endpoint and the public manifest at saylorinnovations.com/.well-known/x402.json.

npm run seed:saylor-official          # local
npm run seed:saylor-official:remote   # production

How providers actually get paid

x402 payments settle peer-to-peer — agent to payTo wallet — never through this bazaar. So listing here doesn't change how you get paid, it changes how many agents find the endpoint to pay. There's no platform fee on the transaction itself today; the plan is to keep discovery free and, if/when it makes sense, monetize optional things like featured placement or verified-provider tooling rather than taxing the payment path.

How listing works

No signup. POST the URL of your own .well-known/x402.json (or equivalent) manifest:
