BONK token liquidity data via x402 micropayment on Base network for $0.02/request
What it does
This endpoint provides DeFi liquidity data for the BONK token, accessible at `https://lowpaymentfee.com/api/v1/defi/BONK/liquidity`. It is part of a broader suite of pay-per-call APIs offered by lowpaymentfee.com, covering data analytics, AI/ML inference, finance/Web3, and infrastructure utilities. The endpoint uses the x402 payment protocol, settling in USDC on the Base network.
Pricing is $0.02 per request (the x402 challenge advertises a maxAmountRequired of 20,000 base units of USDC, which has 6 decimals, equaling $0.02). No API keys, subscriptions, or rate limits are required — callers simply attach an x402 payment header to each POST request. The endpoint returns JSON (`application/json` mime type) and has a payment timeout of 300 seconds.
Documentation is extremely sparse. The provider's landing page lists many endpoints at a uniform $0.02 price point, but 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 BONK liquidity response contains. The endpoint is confirmed live (returns a proper 402 challenge), but the actual data quality and response structure are unknown.

Quality
The endpoint is confirmed live with a valid x402 402 challenge, and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no request/response examples, no documentation beyond a landing page listing, and the specific BONK liquidity endpoint is not even listed on the homepage (only generic categories are shown). This is effectively a stub listing.
