Pay-per-call ACH endpoint on Base via x402 — $0.02/request in USDC, no API keys required.
What it does
This endpoint at `/api/v1/ach/92` is part of the lowpaymentfee.com platform, which offers a collection of pay-per-request APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services. All endpoints use the x402 payment protocol, settling in USDC on the Base network. The listed price is $0.02 per request with no API keys, no rate limits, and no minimum commitments.
The specific endpoint `/api/v1/ach/92` is labeled "Premium API Access" but its actual functionality is unclear — the path suggests ACH (Automated Clearing House) banking or payment-related data, but no documentation, request/response schemas, or examples are available. The x402 challenge confirms the endpoint is live and accepts POST requests, requiring up to 20,000 base units of USDC (i.e., $0.02) per call on the Base network. Payment is made via the x402 `exact` scheme to the specified wallet address.
The broader lowpaymentfee.com platform lists 16+ endpoints across categories like sentiment analysis, text summarization, geocoding, price feeds, and more — all at the same $0.02 price point. However, documentation pages (`/docs`, `/pricing`, `/README`) returned only a "Connect wallet" prompt with no substantive content, so the actual capabilities, input formats, and response structures of this or any endpoint remain unverified.
