Real-time MATIC token price via x402 micropayment on Base for $0.02 per request.
What it does
This endpoint returns the current price of the MATIC (Polygon) token. It is part of a broader suite of pay-per-call APIs hosted at lowpaymentfee.com, covering finance, crypto, AI/ML, data analytics, and utility services. All endpoints use the x402 protocol on the Base network, settling payments in USDC at $0.02 per request with no API keys, rate limits, or subscriptions required.
The specific endpoint at `/api/v1/tokens/MATIC/price` accepts POST requests and returns JSON. Payment is handled via the x402 `X-PAYMENT` header using the "exact" scheme, with a max amount of 20,000 base units of USDC (0.02 USD, since USDC uses 6 decimals). The payment is sent to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` on the Base network, with a timeout of 300 seconds.
Documentation beyond the landing page is 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 responses, and no description of the response format. The endpoint is confirmed live (returns a proper 402 challenge), but the exact response payload structure is unknown.

Quality
The endpoint is live and returns a valid x402 402 challenge with clear pricing and payment details. However, there is no OpenAPI schema, no example request/response, and all documentation pages beyond the landing page are empty (just 'Connect wallet'). The response format is entirely unknown.
Warnings
- —No OpenAPI or schema documentation available for this endpoint
- —Response payload structure is unknown — no examples found anywhere in crawled content
- —All doc/pricing/API/README pages render only 'Connect wallet' with no useful content
- —The endpoint path /api/v1/tokens/MATIC/price is not listed on the landing page (landing page lists /api/v1/crypto/quotes and /api/v1/finance/prices instead), so its exact relationship to the advertised API suite is unclear
