Checks an x402 (HTTP 402 payment) endpoint before you pay: one unpaid GET, then the HTTP status, whether a 402 challenge with an accepts list is present, the payment networks, asset, price and pay-to address format, CORS header and response time. Does not pay, does not verify the seller's identity or reputation, and gives one sample, not uptime.

Spot price: the on-chain DEX price for SOL, BTC or ETH, the median of deep USDC pools on Solana, Ethereum and Base read from chain state, and the pools that served it. Use when you need to answer: What is the spot price, without picking a venue? Any other symbol answers 400 with the supported list and is never billed.

Your own purchase history, keyed to the wallet that pays for the call - no wallet parameter, no signup: the x402 payment IS the identity, so nobody can read another wallet's profile.
