What it does

This endpoint at lowpaymentfee.com provides access to Uniswap DeFi position data through a pay-per-call x402 protocol. The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) with a maximum cost of $0.02 per request (20,000 base units at 6 decimals). No API keys, rate limits, or upfront commitments are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.

The provider (lowpaymentfee.com) hosts a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3, and utility services, all priced at $0.02 per request on the Base network. The specific endpoint `/api/v1/defi/uniswap/positions` is categorized under Finance & Web3 and is intended to return Uniswap liquidity position data, though detailed documentation on request parameters and response schema is not available from the crawled material. The endpoint is live and returns a proper 402 challenge when called without payment.

Because the provider's docs, pricing, and README pages all resolve to a minimal "Connect wallet" stub, there is no published documentation describing the request body format, required fields, or response structure for this endpoint. Callers will need to experiment or contact the provider to learn the expected POST body schema.

Quality

0.35/ 1.00

The endpoint is live and returns a valid x402 402 challenge with clear pricing and asset info. However, there is no published documentation, no OpenAPI schema, no request/response examples, and the docs/pricing/README pages are all empty stubs. The request body and response format are entirely unknown, making this effectively a stub listing.

Warnings

  • No API documentation available — docs, pricing, and README pages all return only a 'Connect wallet' stub.
  • Request body schema is unknown; the example_request_json is speculative based on common DeFi API patterns.
  • Response schema is completely undocumented; example_response_json is null.
  • This specific endpoint (/api/v1/defi/uniswap/positions) is not listed on the provider's homepage catalog, raising questions about its status.
