OHLCV candlestick data for SAND (The Sandbox) via pay-per-request x402 on Base.
What it does
This endpoint provides OHLCV (Open, High, Low, Close, Volume) candlestick data for the SAND cryptocurrency token. It is part of the lowpaymentfee.com platform, which offers a broad suite of data, analytics, AI, finance, and utility APIs — all gated behind the x402 payment protocol on the Base network.
The endpoint is live and returns a standard x402 402 challenge when called without payment. Each request costs $0.02 (20,000 base units of USDC on Base, which has 6 decimals). Payment is settled on-chain via USDC (contract 0x8335…2913) on Base to the provider's address. No API keys, rate limits, or subscriptions are required — callers simply attach an x402 payment header to each request.
Documentation beyond the landing page is extremely sparse. The crawled /docs, /api, /pricing, and /README pages all returned only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI spec, no request/response schema, and no example payloads available. The endpoint accepts POST requests and returns application/json, but the exact request body format and response structure for OHLCV data must be inferred or discovered experimentally.

Quality
The endpoint is live and returns a valid x402 402 challenge with clear pricing. However, there is no OpenAPI spec, no request/response schema, no documentation beyond a landing page, and no examples. The actual request body format and response structure are unknown, making this effectively a stub listing.
Warnings
- —No OpenAPI or schema documentation available — request body format is unknown
- —All documentation pages (/docs, /api, /pricing, /README) returned only 'Connect wallet' with no content
- —Response schema for OHLCV data is entirely undocumented; callers must experiment to discover the format
- —Provider hosts many diverse API categories (AI, geocoding, finance, etc.) from a single domain with no visible documentation — exercise caution
