Look up a Base wallet address: native ETH plus balances for a curated list of 195 tokens, read directly from Base chain state via public RPC with a self-hosted reader (no third-party data API). The response includes a coverage field: tokens outside the list with no transfers in the discovery window (default about 28 hours) are not reported. Balances only; no USD valuation.

Income is all USDC received by the provider's payout address on Base, whatever the source. Score: 0-100: 50 x share of checks in the last 72 h that returned valid x402 payment terms + 30 x min(1, log10(1 + USDC received in 7 days) / 4) + 20 x min(1, log10(1 + distinct payers in 7 days) / 3). A provider never checked scores on income only; income is all USDC received by its payout address on Base, whatever the source. JSON: /v1/observatory/providers/call402.com
