SNX liquidity data via x402 micropayment on Base network, $0.02 per request.
What it does
This endpoint provides DeFi liquidity data for the SNX (Synthetix) token, accessible through the x402 payment protocol on the Base network. Each request costs $0.02 (20,000 base units of USDC with 6 decimals) and requires no API keys, rate limits, or prior registration — payment is handled inline via the x402 `X-PAYMENT` header.
The endpoint is part of a broader API platform at lowpaymentfee.com that offers data & analytics, AI/ML inference, finance/Web3, and infrastructure utility endpoints, all priced uniformly at $0.02 per call. The SNX liquidity endpoint specifically falls under the Finance & Web3 category, though it is not explicitly listed on the landing page among the showcased endpoints. The x402 challenge confirms it is live and accepts POST requests, settling payments in USDC (contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`) on Base.
Documentation is extremely sparse — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI schema, no request/response examples, and no description of what fields the liquidity endpoint returns. Users should expect to experiment with POST request bodies to discover the input format, or contact the provider for documentation.

Quality
The x402 challenge is live and confirms pricing and settlement details, but there is zero documentation on request/response schemas, no OpenAPI spec, and the endpoint is not even listed on the provider's landing page. Effectively a stub listing with only payment metadata confirmed.
