Full-history address-poisoning check before you send USDC on Base. Same risk/lookalike/seenBefore logic as /address/check, but funding history comes from ONE Blockscout index call (x402, up to the sender's 500 most recent Base USDC transfers; v2 page fallback) so coverage is usually the sender's full Base USDC history. Body {from, to}. Not charged if the index is down. Cheap partial/RPC tier: POST /address/check ($0.001).

Claim it for free with x402_provider_claim (sign with your payout address), and get an alert within minutes when it stops answering with x402_monitor_create ($5 for 30 days). Both work over MCP (https://logicnodes.io/mcp/v2) or POST https://logicnodes.io/v1/tools/<tool>.

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/kertivo.com
