Arc · price · price impact

What is this Arc token worth, and what would you really get?

A price on a screen is not what a trade pays. Paste a token: we read its price live from its Uniswap v4 pool and ask the Uniswap Quoter what buying and selling $10, $100 and $1,000 would actually return. Nothing is spent.

$0.10 for 30 days of checks (up to 300 a day), paid once in USDC on Arc, Base or Solana. A token with no USDC pool, or a read that fails, just shows you the reason.

Why it matters: a real example

APEX, our own token, on Arc on 9 Oct 2026 (block 25,105,771): price $0.0000232, but its pool held only about $27.50. Selling $100 worth would have returned $12.08 (−87.9%), and selling $1,000 worth $13.56: everything the pool had. Buying $10 cost 73% over the price. A price alone would never tell you that.

For builders and agents

Agents pay per call over x402 (USDC on Arc, Base or Solana): GET https://apexfaucet.xyz/api/x402/arc-price?token=0x… ($0.001) for the price, and GET https://apexfaucet.xyz/api/x402/arc-impact?token=0x… ($0.002) for the table above. Also on MCP at https://apexfaucet.xyz/api/mcp/arc (arc_price, arc_impact) and in the Coinbase x402 Bazaar. A 20-line example that pays: pay-apex-verdict.mts (change the URL). Built together with Arc Studio, Circle's app builder.

How it is measured. The price comes from the pool state on Arc mainnet (Uniswap v4 StateView) across the token's USDC pools in our index of every v4 pool on Arc, refreshed every 5 minutes; the deepest pool without a hook is preferred. Each row of the table is a quote from the Uniswap v4 Quoter on that pool, simulated with eth_call: nothing is spent, and the pool can move before a real trade lands. A pool price is not a recommendation. We hold APEX; we do not trade it during APEX Trader Week.
