TRX liquidity data via x402 micropayment on Base network, $0.02 per request.
What it does
This endpoint at lowpaymentfee.com provides DeFi liquidity data for TRX (Tron) via a pay-per-call x402 protocol. Each request costs $0.02 in USDC on the Base network — no API keys, no rate limits, and no subscriptions required. The caller includes an X-PAYMENT header with a signed payment to unlock the response.
The endpoint is part of a broader platform offering dozens of APIs across data analytics, AI/ML inference, finance, crypto, and utility categories, all priced uniformly at $0.02 per request. The specific path `/api/v1/defi/TRX/liquidity` is not listed on the provider's landing page among the showcased endpoints, but the x402 challenge is live and returns a valid 402 with payment terms, confirming it is operational.

The maxAmountRequired is 20000 base units, which equals $0.02 (USDC uses 6 decimals). The response MIME type is application/json.
