DeFi liquidity data for FLR on the Flare network, paid per-call via x402 on Base.
What it does
This endpoint at lowpaymentfee.com provides DeFi liquidity data for FLR (Flare) via a POST request to `/api/v1/defi/FLR/liquidity`. It is part of a broader suite of pay-per-request APIs offered by lowpaymentfee.com spanning data analytics, AI/ML inference, finance/Web3, and infrastructure utilities. All endpoints use the x402 payment protocol, settling in USDC on the Base network.
The x402 challenge confirms the endpoint is live and accepts payments of up to 20,000 base units of USDC (0x8335…2913 on Base). Since USDC uses 6 decimals, this translates to $0.02 per request, consistent with the site's advertised flat pricing. Payment is made via the `X-PAYMENT` header using the x402 "exact" scheme, with a 300-second timeout window. No API keys or rate limits are advertised; access is gated purely by micropayment.
Documentation is extremely sparse. The crawled docs, API, pricing, and README pages all returned only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI schema, no request/response examples, and no description of what fields the liquidity endpoint accepts or returns. The endpoint is discoverable and marked as accepting HTTP POST with JSON output, but the actual request body schema and response structure are unknown. Users should expect to experiment or contact the provider for integration details.

Quality
The endpoint is confirmed live via a valid x402 402 challenge, 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 returned only a wallet-connect stub. The actual data returned by this endpoint is entirely unknown, making this effectively a stub listing.
Warnings
- —No API documentation available — docs, pricing, API, and README pages all render only a 'Connect wallet' prompt with no technical content.

- —The endpoint path suggests FLR/Flare DeFi liquidity data, but this is inferred from the URL alone — no description confirms it.
