What it does

lowpaymentfee.com is a pay-per-request API platform that uses the x402 protocol to accept USDC payments on the Base network. The specific endpoint `/api/v1/wire/110` is listed as "Premium API Access" and returns a 402 challenge requesting up to 20,000 base units of USDC (i.e., $0.02 given USDC's 6 decimals) per call. The platform advertises no API keys, no rate limits, and instant access — callers simply attach an X-PAYMENT header with a valid x402 payment proof.

The broader lowpaymentfee.com platform offers endpoints across four categories: Data & Analytics (metrics, reports, data export, insights), AI & Machine Learning (sentiment analysis, text summarization, classification, embeddings), Finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and Infrastructure utilities (geocoding, validation, conversion, generation). All endpoints are listed at $0.02 per request. However, the specific endpoint being listed here (`/api/v1/wire/110`) is labeled generically as "Premium API Access" and does not appear in the site's public API catalog, so its exact functionality is unclear.

Payments settle on Base to the address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` using USDC (`0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`). The endpoint accepts POST requests and returns `application/json`. Documentation pages on the site (docs, pricing, README) all resolve but show only a "Connect wallet" prompt with no substantive content, so detailed request/response schemas are unavailable.

The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base), but the specific functionality of /api/v1/wire/110 is unknown — it doesn't appear in the site's public catalog. Documentation pages are empty ("Connect wallet" only), there is no OpenAPI spec, and no request/response schema is available. This is effectively a stub listing.

Warnings

  • —The endpoint /api/v1/wire/110 is not listed in the site's public API catalog; its actual functionality is unknown.
  • —All documentation pages (docs, pricing, README) return only a 'Connect wallet' prompt with no substantive content.
  • —No OpenAPI spec, request schema, or response schema is available — callers cannot know what to send or expect back.
  • —The platform lists many endpoint categories (AI, finance, data, infrastructure) but none can be verified as functional from the crawl.
