x402-gated loan data endpoint on Base, pay $0.02 per request in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to a loan resource (ID 85) via the x402 payment protocol. It is part of a broader platform offering pay-per-request APIs across data analytics, AI/ML, finance/Web3, and infrastructure categories — all priced at $0.02 per call, settled in USDC on the Base network.
The specific endpoint `/api/v1/loans/85` is not listed on the provider's public landing page among the advertised API categories, so its exact response payload is unclear. The landing page groups endpoints into Data & Analytics, AI & Machine Learning, Finance & Web3, and Infrastructure, but no "loans" category is shown. The x402 challenge confirms the endpoint is live and accepts POST requests with an exact-scheme payment of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. Payment is sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a 300-second timeout.
Documentation is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI spec, no request/response schema, and no description of what the loans endpoint returns. The platform advertises no API keys, no rate limits, and instant access, but specifics about the loan data (fields, format, source) are entirely unknown.

Quality
The x402 challenge is live and confirms pricing and payment details, but there is zero documentation on what the /loans/85 endpoint actually returns. No OpenAPI spec, no examples, and the endpoint isn't even listed on the provider's own landing page. Effectively a stub listing.
Warnings
- —The /api/v1/loans/85 endpoint is not listed among the provider's publicly advertised APIs — its purpose and response schema are unknown.
- —All documentation pages (/docs, /pricing, /api, /README) render only a 'Connect wallet' prompt with no usable content.
- —No OpenAPI spec or response schema is available; the actual data returned is entirely undocumented.
- —The endpoint path suggests a single fixed resource (loan ID 85) rather than a parameterized query — unclear if other IDs exist.
