BLUR liquidity data via x402 micropayment on Base — $0.02 per request in USDC.
What it does
This endpoint provides DeFi liquidity data for the BLUR token/protocol, accessible through the x402 payment protocol on the Base network. Each request costs 20,000 base units of USDC (0.02 USD) paid per call with no API keys, rate limits, or subscriptions required.
The endpoint is part of a broader suite of APIs offered by lowpaymentfee.com, which spans data analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced uniformly at $0.02 per request. Payment is settled on-chain via USDC on Base (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3.
Documentation is extremely sparse. The crawled 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 BLUR liquidity endpoint accepts or returns. The endpoint is confirmed live (returns a proper 402 x402 challenge), but the actual data format and parameters must be discovered experimentally.

Quality
The endpoint is confirmed live via a valid 402 x402 challenge, and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no request/response examples, and all documentation pages returned only a wallet-connect prompt. The actual data contract is unknown, making this effectively a stub listing.

- —No OpenAPI or output schema describing request parameters or response format
- —Request/response structure for BLUR liquidity data must be discovered experimentally
- —The endpoint description is generic ('Premium API Access') and does not describe the data returned
