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 specific loan record (ID 84) via the x402 payment protocol. The endpoint is live and returns a 402 challenge requiring payment in USDC on the Base network. The price per request is $0.02 (20,000 base units of USDC with 6 decimals). Payment is made via the x402 "exact" scheme to a specified wallet address, with no API keys or rate limits required.
lowpaymentfee.com hosts a broader suite of x402-gated APIs spanning data & analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints on the platform are priced at $0.02 per request and settle on the Base network using USDC.
The specific endpoint `/api/v1/loans/84` is labeled "Premium API Access" in the x402 challenge but no further documentation describes the loan data schema, request parameters, or response format. The docs, pricing, and API pages on the site require a wallet connection and provide no additional readable content. Without an OpenAPI spec, response examples, or detailed documentation, the exact shape of the data returned is unknown.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI spec, no response schema, no request parameter documentation, and no example responses. The endpoint path suggests loan data but the description is generic ("Premium API Access"). Docs pages are empty behind a wallet gate. This is effectively a stub listing.
Warnings
- —No OpenAPI or schema documentation available — response format is entirely unknown
- —The endpoint path /api/v1/loans/84 references a specific loan ID but no documentation explains what loan data is returned or what parameters are accepted
- —All documentation pages (docs, pricing, API, README) are gated behind wallet connection and contain no readable content
- —The generic label 'Premium API Access' does not describe the actual functionality
