Get the current STX token price via x402 micropayment on Base for $0.02 per request.
What it does
This endpoint returns the current price of the STX (Stacks) token. It is part of the lowpaymentfee.com platform, which offers a suite of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and utility services. All endpoints use the x402 payment protocol, settling in USDC on the Base network.
The specific endpoint `/api/v1/tokens/STX/price` is a POST endpoint that returns JSON. The x402 challenge advertises a maximum cost of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 per request (USDC uses 6 decimals). No API keys or rate limits are required — callers simply attach an x402 payment header to each request. The payment timeout is 300 seconds.
The broader lowpaymentfee.com platform lists additional endpoints for token quotes, exchange rates, gas estimates, sentiment analysis, text summarization, classification, embeddings, geocoding, validation, conversion, and data export — all priced at $0.02 per call. Documentation pages exist but appear to require a wallet connection and contain no further technical detail at crawl time.

Quality
The x402 challenge is live and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no documented request/response body format, no example responses, and the docs/pricing/README pages all render only a wallet-connect prompt with no usable content. The actual response shape for the STX price endpoint must be inferred.
Warnings
- —No request or response schema documented — callers must discover the payload format experimentally.
- —Documentation, pricing, and README pages are effectively empty (wallet-connect gate only).
- —No SLA, rate-limit, or uptime guarantees are documented.
- —The platform lists many endpoints but it is unclear which are fully functional beyond this one.
