What it does

This endpoint at lowpaymentfee.com provides premium API access to a customer resource (ID 86) via the x402 payment protocol. It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) at a cost of $0.02 per request (20,000 base units with 6 decimals). No API keys or rate limits are required; callers simply attach an X-PAYMENT header with a valid x402 payment proof.

The specific endpoint `/api/v1/customers/86` appears to be part of a broader platform hosted at lowpaymentfee.com that offers multiple API categories including data & analytics, AI & machine learning, finance & Web3, and infrastructure utilities — all priced uniformly at $0.02 per request. However, the crawled documentation pages (docs, pricing, README) returned only a wallet-connect prompt with no substantive content, so the exact schema of the customer resource, its input parameters, and response fields remain undocumented.

The endpoint is live and returns a well-formed 402 challenge with x402 version 1. The payment timeout is 300 seconds. Because there is no OpenAPI spec, no request/response schema documentation, and the crawled pages are effectively empty, the actual functionality behind this specific customer endpoint is unclear — it could be a demo or placeholder resource.

The endpoint is live and returns a valid x402 402 challenge, but there is no OpenAPI spec, no request/response schema, and all documentation pages are empty (wallet-connect only). The purpose of the /customers/86 resource is undocumented, making this effectively a stub listing.

Warnings

  • —No OpenAPI or schema documentation available — request and response formats are unknown
  • —All doc/pricing/README pages return only a wallet-connect prompt with no content
  • —The specific /api/v1/customers/86 endpoint purpose is unclear; may be a demo or placeholder
  • —No examples of successful responses are available
