Real-time SUI token price via x402 micropayment on Base for $0.02 per request.
What it does
This endpoint returns the current price of the SUI token, accessible through the x402 payment protocol. It is part of a broader API platform hosted at lowpaymentfee.com that offers data & analytics, AI/ML inference, finance/Web3, and infrastructure utility endpoints — all gated behind x402 micropayments at $0.02 per call.
The specific endpoint `/api/v1/tokens/SUI/price` accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913). The x402 challenge advertises a maxAmountRequired of 20,000 base units, which at 6 decimals for USDC equals $0.02 — consistent with the site's published pricing. No API keys or rate limits are required; access is granted per-request upon valid payment.
Documentation is extremely sparse. The docs, API reference, pricing, and README pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI spec, no request/response schema documentation, and no usage examples available from the crawled material. The endpoint is confirmed live (402 challenge returned), but the exact response format must be inferred from the endpoint path and description.

Quality
The endpoint is confirmed live via a valid x402 402 challenge, and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI spec, no request/response schema, no documentation beyond a wallet-connect prompt, and no examples. The response format is entirely unknown, making this effectively a stub listing.
Warnings
- —No documentation available — docs, API, pricing, and README pages all show only 'Connect wallet'
- —No OpenAPI or schema definition found for request or response payloads
- —Response format for /api/v1/tokens/SUI/price is completely undocumented and must be discovered empirically
- —The broader platform lists many endpoints but none have documented schemas
