Pay-per-call token data for INJ via x402 on Base, settled in USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides token data for INJ (Injective) through an x402-gated API. The specific endpoint `/api/v1/tokens/INJ` accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) at a cost of $0.02 per request (maxAmountRequired of 20,000 base units with 6 decimals). No API keys or rate limits are advertised; access is granted per-call via the x402 payment protocol.
The provider, lowpaymentfee.com, hosts a broad catalog of pay-per-call endpoints spanning data analytics, AI/ML inference, finance/Web3 market data, and utility services — all uniformly priced at $0.02 per request. This particular endpoint falls under the Finance & Web3 category. However, documentation is extremely sparse: the docs, pricing, and API pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The endpoint is confirmed live (returns a valid x402 402 challenge), but the exact shape of the request body and response data must be discovered experimentally.

Quality
The endpoint is confirmed live with a valid x402 402 challenge and clear pricing ($0.02 USDC on Base). However, there is no OpenAPI spec, no request/response schema, no examples, and all documentation pages render only 'Connect wallet' with no useful content. The actual data returned is unknown.
Warnings
- —No API documentation available — docs, pricing, and API pages all show only 'Connect wallet'
- —No OpenAPI or JSON schema for request or response bodies
- —Exact response format for /api/v1/tokens/INJ is undocumented and must be discovered experimentally
- —Provider hosts many diverse endpoints (AI, analytics, finance, utils) all at the same price, which may indicate a generic wrapper rather than deep data coverage
