Pay-per-request ACH endpoint on Base via x402 — $0.02/call in USDC, no API keys required.
What it does
This endpoint at `/api/v1/ach/182` 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 protocol on the Base network, accepting USDC payments with no API keys, no rate limits, and no subscriptions — just a per-call micropayment.
The specific endpoint `/api/v1/ach/182` is listed under the generic title "Premium API Access." The platform does not provide documentation explaining what this particular route returns or what input it expects. The path segment "ach/182" suggests it may relate to ACH (Automated Clearing House) banking data or payment processing, but this is speculative — no schema, example request, or example response is available from the crawled material. The endpoint is confirmed live: it returns a valid x402 challenge (HTTP 402) requesting up to 20,000 base units of USDC (0.02 USD) on the Base network.
The broader lowpaymentfee.com platform advertises uniform $0.02 pricing across all endpoints, with payment settled on-chain via USDC on Base to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3`. The site's docs, pricing, and API pages all render only a "Connect wallet" prompt with no further technical documentation, making it impossible to verify the actual functionality behind this or any other endpoint on the platform.

Quality
The endpoint is live and returns a valid x402 challenge, but there is zero documentation on what the endpoint actually does, what inputs it accepts, or what it returns. The docs, pricing, and API pages are all empty beyond a wallet-connect prompt. The path hints at ACH functionality but nothing is confirmed.
Warnings
