GET /api/chain/token-balance

unprobed

Balance of an ERC-20 token for an address, already divided by the token's own decimals and labelled with its symbol, plus the raw atomic amount. Accepts a contract address or a known alias (usdc, usdt, weth) where the alias exists for that chain.

Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.

The catalog declares GET. A 402 answer carries the payment requirements in the JSON body and, for x402 v2, base64 in the PAYMENT-REQUIRED header. This page never sends a payment.
