GMX liquidity data via x402 micropayment on Base — $0.02 per request, no API key needed.
What it does
This endpoint at lowpaymentfee.com provides DeFi liquidity data for the GMX protocol, accessible via the x402 payment protocol. Each request costs $0.02 (20,000 base units of USDC on the Base network, where USDC has 6 decimals). No API keys or accounts are required — callers simply attach an x402 payment header with each request.
The endpoint accepts POST requests and returns JSON. It is part of a broader suite of pay-per-call APIs offered by lowpaymentfee.com spanning data analytics, AI/ML inference, finance/Web3, and utility services, all priced at $0.02 per call. The x402 challenge was successfully captured, confirming the endpoint is live and accepting payment challenges on the Base L2 network, settling in USDC (contract 0x8335…2913).
Documentation is extremely sparse — the docs, API, pricing, and README pages all returned only a "Connect wallet" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no description of what fields the GMX liquidity endpoint accepts or returns. The endpoint's actual data coverage (which GMX markets, which chains, historical vs. real-time) is unknown from the available material.

Quality
The x402 challenge is live and pricing is clear ($0.02/request in USDC on Base). However, there is no OpenAPI schema, no request/response examples, and all documentation pages are empty stubs. The actual data returned by this endpoint is entirely unknown, making it effectively a stub listing.
Warnings
- —No documentation available — docs, API, pricing, and README pages all return only 'Connect wallet' with no content.
- —No OpenAPI or request/response schema provided; input parameters and output fields are unknown.
- —Endpoint purpose inferred solely from URL path '/api/v1/defi/GMX/liquidity' — actual functionality unverified.
- —The broader lowpaymentfee.com platform lists many diverse endpoints (AI, geocoding, finance) at identical pricing, which may indicate a generic wrapper rather than a specialized data provider.
