What it does

This endpoint at lowpaymentfee.com returns floor-price data for NFT collection ID 26. It is part of a broader suite of pay-per-call APIs offered by lowpaymentfee.com, all priced at $0.02 per request and settled in USDC on the Base network via the x402 protocol. No API keys or accounts are required — callers simply attach an x402 payment header to each POST request.

The x402 challenge confirms the endpoint is live, accepting payments to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 in USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) on Base. The maxAmountRequired is 20000 base units, which at 6 decimals equals $0.02. The response MIME type is application/json.

Documentation is extremely sparse. The provider's landing page lists many API categories (data & analytics, AI/ML, finance/Web3, infrastructure) but provides no request/response schemas, parameter descriptions, or example payloads for any endpoint. The specific collections/floor endpoint is not listed on the homepage, so its exact input parameters and response shape are unknown. The docs, pricing, and API pages all render only a "Connect wallet" prompt with no additional content.

Quality

0.35/ 1.00

The x402 challenge is live and confirms pricing and payment details, but there is no documentation, no request/response schema, no examples, and the specific endpoint isn't even listed on the provider's homepage. Effectively a stub with verified liveness.

Warnings

  • —No request or response schema documented — input parameters and output format are unknown
  • —The /api/v1/collections/26/floor endpoint is not listed on the provider's homepage; its purpose is inferred from the URL path
  • —All documentation pages (docs, pricing, API, README) render only a 'Connect wallet' prompt with no useful content
  • —No OpenAPI spec or ai-plugin manifest available
