x402-gated Stripe charges endpoint on Base, pay $0.02 per request in USDC.
What it does
This endpoint at lowpaymentfee.com provides an x402-protocol-gated API under the path `/api/v1/stripe/charges/165`, described by the provider as "Premium API Access." It is part of a broader platform offering dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all priced at $0.02 per request and settled in USDC on the Base network.
The specific function of the `/api/v1/stripe/charges/165` endpoint is not documented beyond its title. The URL path suggests it may relate to retrieving or creating Stripe charge objects (charge ID 165), but no request/response schema, parameter documentation, or usage examples are provided by the site. The crawled docs, pricing, and README pages all returned only a "Connect wallet" prompt with no additional content.
Payment is handled via the x402 exact-payment scheme. The 402 challenge specifies a max amount of 20,000 base units of USDC (contract `0x8335…2913` on Base), which equals $0.02 given USDC's 6 decimals. No API keys are required; callers attach an `X-PAYMENT` header with a valid x402 payment proof. The endpoint accepts POST requests and has a payment timeout of 300 seconds.

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base), but there is no documentation of what the endpoint actually returns, no request/response schema, and no examples. The docs, pricing, and README pages are all empty beyond a wallet-connect prompt. The specific purpose of 'stripe/charges/165' is unclear.
Warnings
- —No request or response schema available — the actual behavior of this endpoint is unknown
- —All documentation pages (docs, pricing, README, api) return only 'Connect wallet' with no content
- —The endpoint path suggests a fixed charge ID (165), which may indicate a demo or placeholder rather than a general-purpose API
