x402-gated Stripe charges endpoint on Base, paying $0.02 in USDC per request.
What it does
This endpoint at lowpaymentfee.com provides a pay-per-call "Premium API Access" service gated by the x402 protocol. The specific path `/api/v1/stripe/charges/128` appears to be one of many endpoints offered by the provider, which hosts a broad catalog spanning data & analytics, AI/ML inference, finance & Web3 data, and infrastructure utilities — all priced at $0.02 per request.
Payment is settled on the Base network using USDC (contract 0x8335…2913) via the x402 exact-payment scheme. The maximum amount required is 20,000 base units, which at 6 decimals equals $0.02 USD. No API keys or rate limits are advertised; callers simply attach an X-PAYMENT header with a valid x402 payment proof. The endpoint accepts POST requests and returns application/json.
Documentation is extremely sparse — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further content. The specific functionality behind the `/api/v1/stripe/charges/128` path is not documented; the name "Premium API Access" and the path segment "stripe/charges" suggest it may proxy or wrap Stripe charge creation, but this is unconfirmed. Without request/response schemas or usage examples, callers will need to experiment to determine the expected input and output formats.
