x402-payable loan data endpoint on Base, settling in USDC at $0.02 per request.
What it does
This endpoint at lowpaymentfee.com provides access to a specific loan record (ID 82) via the x402 payment protocol. It accepts POST requests and returns JSON data after receiving a valid USDC micropayment on the Base network. The cost per call is $0.02 (20,000 base units of USDC with 6 decimals).
The endpoint is part of a broader platform (lowpaymentfee.com) that offers a variety of x402-payable APIs spanning data & analytics, AI & machine learning (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 uniformly at $0.02 per request with no API keys, no rate limits, and no minimum commitments.
The specific resource at `/api/v1/loans/82` is labeled "Premium API Access" in the x402 challenge but no further documentation describes the loan data schema or what fields are returned. The docs, pricing, and API pages on the site are gated behind a wallet-connect flow and provide no additional technical detail. Without an OpenAPI spec, response examples, or detailed documentation, the exact shape and content of the response remain unknown.

Quality
The endpoint is live and returns a valid x402 challenge, but there is no OpenAPI spec, no response schema, no example responses, and the docs pages are empty (wallet-gated). The specific purpose of the /loans/82 resource is undocumented beyond the generic label 'Premium API Access'. This is effectively a stub listing.
Warnings
- —No OpenAPI or schema documentation available for this endpoint
