Download backup data for August 2026 via x402 micropayment on Base network.
What it does
This endpoint at lowpaymentfee.com provides access to a downloadable backup file for the period 2026-08, gated behind an x402 payment challenge. The endpoint accepts POST requests and returns application/json content. Payment is settled on the Base network using USDC (contract 0x8335…2913) with a maximum cost of $0.02 per request (20,000 base units at 6 decimals).
The broader lowpaymentfee.com platform advertises a suite of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all priced at $0.02 per request with no API keys, no rate limits, and no commitments required. However, this specific endpoint is scoped to backup downloads rather than the analytics or AI categories. Documentation beyond the landing page is essentially empty (pages return only a "Connect wallet" prompt), so the exact schema of the backup payload, required POST body fields, and the nature of the backup data are unknown.
Because the endpoint returned a well-formed 402 challenge during probing, it is confirmed live. The x402 version is 1, the payment scheme is "exact", and the timeout window is 300 seconds. No OpenAPI spec, AI plugin manifest, or robots/agents.txt were found.

Quality
The endpoint is confirmed live via a valid 402 challenge, and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI spec, no documentation beyond a wallet-connect prompt, no request/response schema, and the nature of the "backup" data is entirely opaque. This is effectively a stub listing.
Warnings
- —No OpenAPI or schema documentation available — request body and response format are unknown.
- —All documentation pages (docs, api, pricing, README) return only a 'Connect wallet' prompt with no substantive content.
- —The nature and contents of the '2026-08 backup' are unspecified; the endpoint name suggests a future date which is suspicious.
