OHLCV candlestick data for CELO via x402 micropayment on Base network at $0.02/request.
What it does
This endpoint provides OHLCV (Open, High, Low, Close, Volume) candlestick data for the CELO cryptocurrency token. It is part of the lowpaymentfee.com platform, which offers a suite of data, analytics, AI, finance, and utility APIs all gated behind x402 micropayments on the Base network.
The endpoint accepts POST requests and is paid per-call using USDC on Base. The x402 challenge indicates a maximum cost of 20,000 base units of USDC (6 decimals), which equals $0.02 per request. No API keys or rate limits are required — payment is the only authentication mechanism. The platform advertises instant access with no minimums or commitments.
The broader lowpaymentfee.com platform also offers endpoints for token quotes, gas estimates, exchange rates, price feeds, sentiment analysis, text summarization, classification, embeddings, geocoding, validation, conversion, and data export — all at the same $0.02/request price point. Documentation beyond the landing page is sparse; the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further technical detail.

}Endpoint
Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02/request in USDC on Base). However, there is no OpenAPI schema, no documented request/response format, no examples, and all documentation pages return only a wallet-connect prompt. The request and response schemas are entirely inferred.
Warnings
- —No documentation available — docs, pricing, API, and README pages all show only 'Connect wallet' with no technical content.
- —Request body schema and response format are unknown; example_request_json is speculative.
- —No information on data sources, update frequency, or supported intervals for OHLCV data.
- —Platform appears to be a generic multi-endpoint storefront; quality and reliability of underlying data is unverified.
