Onchain & crypto

Smallest end-to-end test of an x402 client on Base: one call with no required parameters returns server time (ISO 8601 and Unix ms), a request id, the seller payTo, chain id and an echo of your optional text, only after a real settlement. Use this when an agent needs to prove its payment flow works, measure round-trip latency or run a cheap scheduled canary against a live seller. No upstream, no model inference; paid round trip 1 to 2 s (settlement first). Free sample at /api/x402-ping/sample.

Token intelligence for any Base (EVM) token contract address. Returns DexScreener market data (price USD, liquidity, FDV, market cap, 24h volume and change, pair age, DEX) together with GoPlus security checks (honeypot, buy/sell tax, verified source, upgradeable proxy, mintable supply, pausable transfers, owner privileges, holder concentration) and a deterministic rule-based risk score with flags. Use it to screen a Base token before buying, swapping or interacting with it.
