DeFi liquidity data for FLOW token, paid per-call via x402 on Base network.
What it does
This endpoint at lowpaymentfee.com provides DeFi liquidity data for the FLOW token. It is part of a broader API platform that offers data & analytics, AI/ML inference, finance/Web3, and infrastructure endpoints, all payable per-request via the x402 protocol on the Base network using USDC.
The specific endpoint `/api/v1/defi/FLOW/liquidity` accepts POST requests and returns JSON. The x402 challenge indicates a maximum cost of 20,000 base units of USDC (0.02 USD per request), consistent with the platform's uniform $0.02/request pricing. Payment is settled on-chain on Base to the specified wallet address, with no API keys, rate limits, or subscriptions required.
Documentation is extremely sparse — the docs, pricing, and API pages all render only a "Connect wallet" prompt with no further technical detail. The exact request body schema and response format for this liquidity endpoint are not documented anywhere in the crawled material. The endpoint is live (returning a valid 402 challenge), but without request/response examples or field-level documentation, integrators will need to experiment to determine the expected input and output structure.

Quality
The endpoint is live and returns a valid x402 402 challenge, confirming it exists and accepts payment. However, there is zero documentation on request parameters, response schema, or what 'liquidity' data is actually returned. The docs/pricing/API pages are all blank beyond a wallet-connect prompt. This is effectively a stub listing.
Warnings
- —No request body schema documented — callers must guess or reverse-engineer the expected input
- —No response schema or example available — the actual data returned is unknown
- —All documentation pages (docs, pricing, API, README) render only 'Connect wallet' with no content
- —The endpoint path /api/v1/defi/FLOW/liquidity is not listed on the provider's homepage; only finance and crypto endpoints are shown, raising questions about whether this is a fully supported route
