Pay-per-call Stripe charges endpoint on Base via x402 — $0.02/request in USDC.
What it does
This endpoint at lowpaymentfee.com provides a "Premium API Access" resource related to Stripe charges, accessible via the x402 payment protocol. The endpoint is live and returns a standard 402 challenge requesting payment in USDC on the Base network. The price per call is 20,000 base units of USDC (6 decimals), which equals $0.02 per request. Payment is sent to a specified wallet address, and no API keys or rate limits are required.
The broader lowpaymentfee.com platform advertises a suite of pay-per-call APIs spanning data & analytics (metrics, reports, data export, insights), AI & machine learning (sentiment analysis, text summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation) — all priced at $0.02 per request. However, this specific listing covers the `/api/v1/stripe/charges/99` endpoint. The exact functionality behind this particular route is unclear from the available documentation; the path suggests it may relate to creating or retrieving Stripe charge objects, but no schema, example payloads, or detailed docs were found.
Documentation pages (/docs, /api, /pricing, /README) all returned only a "Connect wallet" prompt with no substantive content. There is no OpenAPI spec, no request/response schema, and no usage examples available. The endpoint accepts POST requests and returns application/json according to the x402 challenge metadata.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing ($0.02 USDC on Base). However, there is no OpenAPI spec, no request/response schema, no documentation content (all doc pages show only 'Connect wallet'), and the actual functionality behind /api/v1/stripe/charges/99 is ambiguous. This is effectively a stub listing.
