Get the current price of LRC (Loopring) via a pay-per-call x402 endpoint on Base.
What it does
This endpoint returns the current price of the LRC (Loopring) token. It is part of the lowpaymentfee.com platform, which offers a suite of data, AI, finance, and utility APIs all gated behind the x402 payment protocol on the Base network. Each call costs $0.02 in USDC (USD Coin), settled on-chain with no API keys, no rate limits, and no subscriptions required.
The specific endpoint at `/api/v1/tokens/LRC/price` accepts POST requests and returns JSON. The x402 challenge confirms the endpoint is live, accepting payments to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` using USDC on Base (contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`). The maximum amount required per call is 20,000 base units of USDC (6 decimals), which equals $0.02.
The broader lowpaymentfee.com platform also offers endpoints for analytics, AI inference (sentiment analysis, summarization, classification, embeddings), exchange rates, gas estimates, geocoding, and more — all at the same $0.02/request price point. Documentation pages exist but appear to require a wallet connection to view, so detailed request/response schemas are not available from the crawl.

Quality
The x402 challenge is live and confirms pricing, network, and asset details. However, no request/response schema, no documentation content (all doc pages just show 'Connect wallet'), and no example payloads are available, making integration details largely unknown.
Warnings
- —No request or response schema documented — the output format of the price data is unknown.
- —All documentation pages (docs, api, pricing, README) require wallet connection and returned no useful content.
- —The endpoint path suggests a single-token price lookup but there is no confirmation of what fields are returned.
