Every agent-payment endpoint claims to work. We scored them all — then spent real USDC to find out which ones actually deliver. This is what the x402 economy looks like when you stop trusting listings.
The other ~24,919 indexed endpoints are open — no payment gate, nothing to settle. We probe those free. The money story is the 15,695 that charge. Solana sweep: 72 doors paid, $0.84 spent, receipts on Solscan. 4,080 indexed.
Free probes can't tell you if an endpoint delivers. A 402 can be perfectly formed, the payTo can match, latency green — and the moment money moves, you get nothing back. So we don't just probe. We buy.
Automated discovery across CDP Bazaar, x402scan, awesome-x402, and direct probes. Every gated endpoint enters the index with full metadata.
A Coinbase-custodied agent wallet signs real USDC payments (EIP-3009). Not simulated. Not testnet. Facilitator receipts are the per-call proof — x402 does not mint a separate on-chain tx per listing.
If data returns and it's useful → returned. If payment settles but nothing comes back → demoted automatically. No human judgment involved.
We attempted a real USDC purchase from every gated endpoint in the ecosystem — 15,695 doors knocked, then knocked again in a rehash pass that re-verified every settle. Across all sweeps, 1,776 payments settled; 1,371 proof-backed. 307 returned usable data — 17.3% of settles delivered. The failures are broken payment paths: the endpoint advertises x402, but checkout fails the moment a real agent arrives with real money. We paid those doors twice and the same doors still failed. "Proof-backed" in the stats bar = settles with a full facilitator receipt or an on-chain-verified unique tx hash. Solana dual-rail is live too: 72 doors paid, $0.84, receipts on Solscan.
We knocked on 43,693 doors with real USDC. 1,776 settled. 307 delivered data. We paid those 15,695 doors twice and confirmed it at scale. 17.3% of settles returned data across both chains. The rest took the money — or broke the moment a real agent arrived with a wallet. That gap is the distance between x402's promise and its reality. We publish both sides of it. And we swept 72 Solana doors too — $0.84, receipts on Solscan, dual-rail live.
Seven surfaces. One mission: make the x402 economy trustworthy at machine speed.
Every directory has a leaderboard. Ours has a spam filter with receipts. These are listings that looked perfect — until we checked who actually gets the money. This board is the reason our leaderboard only ranks domains a real operator runs.
Built for agents first: no accounts, no keys, no signup. Your agent pays per request with x402 USDC on Base — free tier on every core route.
43,693 endpoints scored for integrity. Every score reproducible from public data. 1,371 proof-backed with receipts.
Per-seller behavior scores from real settled receipts: did they deliver, did they prove it, was the data faithful. Grade A–F with full evidence trail. Cold start says "insufficient history" — never fabricated.
Delivery rates from real paid sweeps. 398 cross-domain wallets, 1,776 settles on-chain — Base and Solana. Know which endpoints actually deliver before you pay.
Continuous payTo drift detection across 43,693 endpoints. 988 payTo mismatches in index. Know before your agent pays.
Eleven tools your agent can install natively — trust lookups, mismatch feeds, delivery analytics, the ledger. No HTTP plumbing required.
Full-text search across declassified government documents. JFK, UAP, MKUltra, COINTELPRO — the receipts are public.
Legal open-access routing for scientific papers. Aaron's ghost drives this one — paywall bypass through legitimate channels.
Free tier: 25 calls/day. Free through 2026: every route is open — no accounts, no API keys, no signup. The x402 payment rails stay wired; we simply are not charging this year.
RobotsShop is an autonomous shop operated by the Digital Hubris / AnalogHubris stack. Every number on this page is reproducible from public data. No invented metrics, no paid placement, no sponsored rankings.
Scoring is tamper-resistant: payTo must match listing, bodies must be valid, spam gets penalized. We'd rather index 40K honest endpoints than 400K noisy ones.
This page is semantic. llms.txt is current. The API returns clean JSON. Your agent can browse it directly, hit the REST API, or install the MCP server — whichever it prefers.
The only directory that pays its own listings. When we say an endpoint works, it's because we spent real money and watched it deliver.
