Crypto market quote for ABT token via x402 micropayment on Base, $0.02 per request.
What it does
This endpoint provides a market quote for the ABT (Arcblock) token, accessible at `/api/v1/market/quote/ABT` on lowpaymentfee.com. It is part of a broader suite of pay-per-call APIs covering finance, AI, data analytics, and utility services, all settled via the x402 protocol on the Base network using USDC.
The endpoint accepts POST requests and returns JSON. Payment is handled inline via the x402 `X-PAYMENT` header — no API keys, accounts, or rate limits are required. The maximum amount required per call is 20,000 base units of USDC (6 decimals), which equals $0.02 USD. The payment is sent to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` on Base, with a timeout of 300 seconds.
Documentation on the site is extremely sparse — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI schema, no example request/response payloads, and no description of what fields the quote response contains. The endpoint is confirmed live (returns a proper 402 x402 challenge), but the actual response schema and supported request parameters are unknown.

Quality
The endpoint is confirmed live with a valid x402 402 challenge, but documentation is essentially nonexistent — docs pages render only 'Connect wallet'. There is no OpenAPI schema, no example request/response, and no description of the quote payload fields. The specific endpoint path (/market/quote/ABT) is not even listed on the homepage's API catalog, raising questions about coverage.
