Semilla x402 seller check

Searches the x402 services indexed by AgentsMap by keyword and returns operators, endpoints and recent paid activity.

Checks one Base transaction on-chain: status, block time and every USDC transfer in it; optionally whether it paid the expected address and amount.

Before paying an x402 service: real paid activity of its host or payTo (24h, 7d, 30d, unique payers, volume, first and last payment), observed prices, endpoint health and price or payTo changes, plus daily history.

Prices that comparable x402 endpoints really ask on Base (from their 402 challenges), for a keyword: low, median and high, and the busiest examples with their paid calls.

The x402 sellers on Base with most paid calls in a window (1h, 8h, 24h, 7d or 30d): payments, unique payers and USDC volume, from the AgentsMap index.
