Get the current price of INJ (Injective) token via a pay-per-call x402 endpoint on Base.
What it does
This endpoint returns the current price of the INJ (Injective Protocol) token. It is part of a broader suite of APIs hosted at lowpaymentfee.com, which covers 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/INJ/price` accepts POST requests and returns JSON. Each call costs $0.02 in USDC (maxAmountRequired of 20,000 base units with 6 decimals = $0.02). No API keys or accounts are required — payment is handled inline via the x402 `X-PAYMENT` header. The provider advertises no rate limits and instant access.
The endpoint was confirmed live, returning a proper 402 challenge with x402 version 1. Documentation on the site is minimal — the docs, pricing, and API pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no example request/response payloads, and no description of the response schema. The endpoint likely returns a JSON object containing the INJ token price, but the exact fields are undocumented.

Quality
The endpoint is confirmed live with a valid x402 402 challenge and clear pricing ($0.02/call in USDC on Base). However, there is no OpenAPI spec, no documented request/response schema, no example payloads, and the docs/pricing/API pages are empty beyond a wallet-connect prompt. The listing is functional but minimally documented.
Warnings
- —No OpenAPI or schema documentation available — response format is unknown
- —Docs, pricing, and API pages on the site render only 'Connect wallet' with no technical content
- —No example responses available to verify what fields are returned
- —The broader site lists many endpoint categories but this specific token-price endpoint is not explicitly listed on the homepage (homepage shows /api/v1/finance/prices and /api/v1/crypto/quotes, not /api/v1/tokens/INJ/price)
