How this service works
Free APEX on X1, and free USDC plus APEX on Arc, three times a day. No gas, no sign-up. Plus a swap, a screener, APEX City and token checks.
Output
A JSON object with a breakdown per token (balance, USD price sourced from the deepest Uniswap v4 USDC pool, and USD value), a flag if a token has no pricing pool, and the wallet's total USD value summed across all tokens. Always includes USDC, EURC, and APEX; up to 20 additional tokens can be included via query parameter.
Example use cases
Portfolio snapshot before a trade
“Before I do anything, tell me the current USD value of everything in my Arc wallet 0xAbCd1234abcd1234ABCD1234abcd1234ABCD1234 — show me each token balance and what it's worth.”
Monitor a DAO treasury address
“Check the Arc wallet 0xDEAD000000000000000000000000000000000000 and tell me the total dollar value of its holdings, including USDC, EURC, and APEX.”
Verify token holdings including custom tokens
“Look up wallet 0x9999888877776666555544443333222211110000 on Arc and include these two extra tokens — 0xTokenA000000000000000000000000000000000A and 0xTokenB000000000000000000000000000000000B — in the USD valuation.”
Technical details
Endpoint
GEThttps://apexfaucet.xyz/api/x402/arc-wallet?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a live, USD-denominated snapshot of a full Arc wallet's holdings — especially when you want USDC, EURC, and APEX included automatically alongside arbitrary ERC-20 tokens, and you need honest pool-availability signals rather than silent $0 values for unpriced tokens. Prefer it over generic token price endpoints when you need wallet-level aggregation in one call.
Side effects
- Invalid or malformed wallet address (not a valid 0x 20-byte hex) returns an error before payment is charged
- Token with no Uniswap v4 USDC pool reports missing pool status instead of $0 to avoid silent mispricing
- Multicall3 read failure on-chain results in a refused/error response
- More than 20 custom tokens specified may be truncated or rejected
- Network congestion on Arc may cause slower or failed reads
