x402-price-benchmark

Stop guessing what a price should be: one GET tells you where a price sits in the measured x402 market — cheap, fair or expensive — with the median, the 25th and 90th percentiles, the band, and how many measured prices are behind the comparison. curl: GET /price?amount=0.02 (add &url=https://your.endpoint/path to also compare against that URL's category). Response: {verdict:{label,plain,one_line,rule}, price_position:{percentile_text,band,multiple_of_median}, market:{sample_size,p25,median,p90,bands,fetched_at}, category:{...}, my_price:{...}}. Every figure is a measured amount from the public discovery index, carried with the date it was fetched; nothing is estimated or interpolated. The comparison is served from the bundled snapshot, so the response does not depend on any third party. No keys, no account, one GET, one delivery — 0.02 USDC. A purchase is two calls by design: this first call returns 402 with the price and the payment terms, and you then repeat the same request with the PAYMENT-SIGNATURE header to receive the 200 delivery.
