Check AXS (Axie Infinity) wallet balance via x402 micropayment on Base network.
What it does
This endpoint at lowpaymentfee.com returns wallet balance information for AXS (Axie Infinity Shards) tokens. It is part of a broader platform offering dozens of pay-per-call API endpoints spanning data analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all gated behind the x402 payment protocol on the Base network.
The specific endpoint `/api/v1/wallet/AXS/balance` accepts POST requests and is priced at a maximum of $0.02 per call (20,000 base units of USDC on Base, which has 6 decimals). Payment is settled on-chain via USDC (contract 0x8335…2913) to the provider's address. No API keys or rate limits are advertised; access is granted per-request upon valid x402 payment.
Documentation is extremely sparse. The provider's landing page lists available endpoints and pricing but the /docs, /pricing, and /README 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 usage examples. The endpoint is confirmed live (returns a proper 402 challenge), but the actual response format and required request body fields are unknown.

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 examples, and all documentation pages return only a wallet-connect prompt. The actual behavior of the endpoint is entirely inferred from the URL path.
