MATIC OHLCV candlestick data via x402 micropayment on Base, $0.02 per request.
What it does
This endpoint provides OHLCV (Open, High, Low, Close, Volume) candlestick data for the MATIC cryptocurrency token. It is part of the lowpaymentfee.com platform, which offers a suite of data, AI, finance, and utility APIs all gated behind x402 micropayments on the Base network.
The endpoint is accessed via HTTP POST and is protected by the x402 payment protocol. Each request costs $0.02 (20,000 base units of USDC on Base, which has 6 decimals). Payment is made in USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) to the provider's address on Base. No API keys, rate limits, or subscriptions are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.
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 parameters the OHLCV endpoint accepts (e.g., time range, interval/granularity) or what fields it returns. The endpoint is confirmed live (returns 402 with a valid x402 challenge), but the actual data quality and schema are unknown.

Quality
The endpoint is confirmed live via a valid x402 402 challenge, and pricing is clear ($0.02/request in USDC on Base). However, there is no OpenAPI schema, no request/response examples, and all documentation pages return only a wallet-connect prompt. The actual request parameters and response format are completely unknown, making this effectively a stub listing.
Warnings
- —No documentation available — all doc pages return only 'Connect wallet' with no content
- —No OpenAPI or request/response schema provided; request parameters (timeframe, interval, etc.) are unknown
- —Response format and data fields are entirely undocumented
- —The broader lowpaymentfee.com platform lists many diverse endpoints (AI, analytics, finance, utils) all at $0.02 — data quality and reliability are unverified
