▸ GET /base/address-intelN/A
One call for an address on Base: USDC balance, ETH balance, verified primary Basename, transaction count (nonce) and whether it is a contract. Use it to profile a counterparty or payout wallet before interacting. Replaces four or five separate reads with a single priced request. Query: ?address=0x... $0.01 · — · Base ▸ GET /x402/preflightN/A
Pre-pay Check: Ed25519-signed, deterministic facts about another x402 endpoint before you pay it: challenge validity, reachability and latency, host listing count, payout wallet reuse across hosts, last-called and payer trend from daily Bazaar snapshots. Use it when choosing between paid endpoints. Signed facts you can verify against the published key, not ratings; facts only, no advice. Query: ?url=https://... $0.01 · — · Base ▸ GET /base/basenameN/A
Resolve a Basename (name.base.eth) to its Base address, or an address to its primary Basename, checked both ways so a reverse name is only returned when it resolves back. Use it to turn a human name into a payout address or to label an address. Avoids hand-written ENS-style namehash and resolver calls. Query: ?name=jesse.base.eth or ?address=0x... $0.003 · — · Base ▸ GET /base/tx-statusN/A
Base mainnet transaction status: success, failed or pending, with block, confirmations, gas used, effective gas price, from/to and log count. Use it after sending or receiving a payment to confirm it landed and how deep it is. One normalized JSON answer instead of combining receipt and block calls and computing confirmations yourself. Query: ?hash=0x... $0.002 · — · Base ▸ GET /base/networkN/A
Base mainnet head: latest block number, block age in seconds, base fee and gas price in gwei. Use it to check the chain is advancing and to estimate fees before sending a transaction. One small JSON read instead of several raw RPC calls and unit conversions. $0.001 · — · Base ▸ GET /base/usdc-balanceN/A
