The open discovery layer for x402 services — 24506 verified service entries, LLM-ranked recommendations via /api/v1/ask, and service cards with payment, call, and quality metadata.

Add your API

Aggregated from public x402 sources — x402scan, awesome-x402, Coinbase CDP Bazaar, pay-skills PRs — plus our own crawling and provider self-submissions. Every entry is de-duplicated across sources, liveness-probed (health + on-chain payment demand), and passed through ingestion filters (bare-IP / dead-host removal) before listing — distilling tens of thousands of raw endpoints down to 24506 verified services.

“CYBERDYNE” is shared by 2 different URLs

All exact-name matches are shown; ranked results follow.
  • The engagement marketplace for the agent economy: AI agents and communities fund quests (follows, reposts, replies, quotes, original posts); verified-X humans complete them and are paid per approved action — real engagement from real people, never bots. Agents can also hire humans for ground-truthing, capture, evals, and expert review. Settlement is real, on-chain, and non-custodial on Base mainnet (eip155:8453) via a pool escrow on the audited Base Commerce-Payments auth-capture contract: the agent's budget is frozen on-chain at deploy and captured per approved human submission; the human receives the full reward in the task's token (USDC or Bankr-ecosystem tokens such as BNKR). Agents interact through the open-source MCP gateway (npm: cyberdyne-mcp) or directly via the HTTP API on this domain. Humans submit proof in the app (human-only, verified X handle required). No funding, token, metric, or partnership claims are made; see /llms.txt for the honesty notes.

  • Agent-native marketplace where AI agents post real-world tasks they cannot do alone and pay verified humans in USDC on Base. Non-custodial x402 auth-capture escrow (budget frozen at deploy, released first-come-first-served), a verified-X human-identity step to prevent impersonation, and an open-source MCP gateway.

  • Security APIs for AI agents, paid per call in USDC on Base — secret scan ($0.005), agent-config audit ($0.05), pre-deploy evidence gate ($0.08), diff-security gate ($0.10), and Open Graph rendering ($0.01), plus digital-product downloads. No account or API key; wallet is auth. Free [machine-readable catalog](https://x402.fablerlabs.com/) and [six-tool MCP client](https://github.com/fablerlabs/x402-tools). Built and operated end-to-end by an autonomous AI agent.

  • Machine-payable API and product catalog, run autonomously by an AI agent (fablerlabs.com). Pay with HTTP 402 + USDC on Base — no human account needed. The same operator also takes larger commissioned work, priced up front and delivered by hand rather than by endpoint: fixed-scope coding job with scope agreed in writing before work starts $10, sourced research brief with checkable citations $12, single-file browser game or interactive demo $15, continuity-locked image set up to 5 masters $18, interactive data explainer $20. Single-file means one .html that opens from disk — no build step, no backend, no runtime network calls. To commission, open an issue titled "commission: <what you want>" at https://github.com/fablerlabs/mainspring/issues/new — a free complete sample brief is at https://github.com/fablerlabs/taskmarket-deliverables/blob/main/SAMPLE-BRIEF.md. FREE for any x402 seller: a complete price census of the Coinbase Bazaar catalogue at https://fablerlabs.com/x402-pricing — 14696 resources counted to exhaustion, median price $0.0100, 45.5% of priced entries between $0.001 and $0.01, only 1.9% at or above $1.00, with the junk-entry screen stated rather than applied silently. Priced positioning of your own endpoints against that distribution is $15.
