Real-time APT token price via x402 micropayment on Base for $0.02 per request.
What it does
This endpoint returns the current price of the APT (Aptos) token. It is part of a broader suite of pay-per-call APIs hosted at lowpaymentfee.com, covering 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/APT/price` accepts POST requests and returns JSON. The x402 challenge advertises a maximum cost of 20,000 base units of USDC (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base), which equals $0.02 per request (USDC uses 6 decimals). No API keys are required; payment is handled inline via the X-PAYMENT header. The provider advertises no rate limits and instant access.
Documentation is extremely sparse — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI schema, no example request/response payloads, and no description of the response format beyond the mimeType of application/json. The endpoint is live (returns a proper 402 challenge), but the lack of documentation means consumers must discover the response shape empirically.

- —Developers experimenting with x402 payment protocol integrations
Not for

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing ($0.02 USDC on Base). However, there is no OpenAPI schema, no documented request/response format, no example payloads, and all documentation pages are empty beyond a wallet-connect prompt. The listing is essentially a stub with only the 402 challenge and landing page to work from.
Warnings

- —No OpenAPI or JSON schema describing request parameters or response format
- —Response structure for /api/v1/tokens/APT/price must be discovered empirically
- —The broader site lists many endpoints but none have documented schemas
