Get the current price of GRT (The Graph) token via a pay-per-call x402 endpoint on Base.
What it does
This endpoint returns the current price of the GRT (The Graph) token. It is part of a broader suite of APIs offered by lowpaymentfee.com, which covers data analytics, AI/ML inference, finance/Web3 data, and utility services — all accessible via the x402 payment protocol on the Base network.
The endpoint accepts POST requests and is paid per call using USDC on Base. The x402 challenge advertises a maxAmountRequired of 20,000 base units of USDC (6 decimals), which equals $0.02 per request. No API keys or account registration are needed; payment is handled inline via the X-PAYMENT header. The provider advertises no rate limits and instant access.
The specific endpoint `/api/v1/tokens/GRT/price` sits within the Finance & Web3 category of the provider's API catalog, alongside other endpoints for price feeds, exchange rates, token quotes, and gas estimates. 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. The response schema and exact fields returned are not documented, so consumers should expect a JSON payload with price information but will need to inspect the actual response to confirm the structure.

Quality
The endpoint is live and returns a valid x402 402 challenge with clear pricing ($0.02 USDC on Base). However, there is no OpenAPI schema, no documented response format, and the docs/pricing/README pages are all empty beyond a wallet-connect prompt. The actual data returned is unknown, making integration speculative.
Warnings
- —No response schema or example response documented — consumers must discover the output format empirically.
- —Docs, pricing, and README pages render only 'Connect wallet' with no technical content.
- —The provider's broader API catalog lists many endpoints but none have detailed documentation visible in the crawl.
- —It is unclear whether this endpoint returns only a spot price or additional metadata (volume, market cap, etc.).
