Verify an onchain payment or investigate a failed Base transaction in one call with transaction, receipt, success status, confirmations, gas and fee context.

Something you cannot do while your agent is dead: keep watching. One paid call buys 7 days of it — on-chain on Base (wallet activity, whale transfers, price crossings, new pools), a dead-man switch that fires when YOUR agent goes silent, a cron/schedule webhook, or a url-change web monitor. Every event carries a signed Ed25519 receipt proving a third party observed it then — which your own logs ca

Check a public website's security hygiene before your agent links to it, recommends it, or sends data to it. One URL in, deterministic JSON out: HTTPS and redirect chain, HSTS, CSP, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, security.txt, robots.txt, sitemap.xml, plus plain-language notes. Private, localhost and raw-IP targets are rejected; error responses are no

Mint a BotPay NFT on Base after an x402 USDC payment.

Generative glyph artwork from verifiable randomness: pass a drand quicknet round number (League of Entropy, one every 3 s) and get its 512x512 SVG drawn by fixed published rules (apexfaucet.xyz/door/glyph.js), the round randomness and BLS signature, and a SHA-256 receipt of the SVG. Anyone can redraw it exactly. From THE DOOR, an open experiment at apexfaucet.xyz/door/.

Which x402 services actually deliver — every one paid-tested with real USDC, receipts on-chain.

Checks a list of payment records for common reconciliation bugs: payments marked settled without an on-chain reference, payer or payee stored as a display name instead of an address, idempotency keys that let the same payment through twice, and ledger counts that differ from the chain scan. Returns the findings per row.

Check whether a wallet currently holds a valid, unexpired Wicked Identity agent-liveness assertion.

Before your agent onboards, pays, or contracts with a counterparty: screen the name against the U.S. Treasury OFAC sanctions lists (SDN + Consolidated non-SDN, synced every 6h) for $0.01.

Concentrated-liquidity range evidence for one Aerodrome Slipstream pool on Base: the narrowest price range that stayed in range for a target share (80/90/95 %) of the last 24-720 h, with in-range %, out-of-range episodes, hourly coverage and block-level evidence from on-chain observations. Useful when choosing or re-centring an LP range. Refused or stale queries return 4xx/503 before any payment.
