Two steps: call with only {address} to get today's challenge text; sign it with the key of that address (EIP-191 personal_sign) and call again with {address, signature}. Same claim for everyone; cooldown and daily total are enforced by a contract with no withdraw function. The day's claims open in three parts (00:00, 08:00, 16:00 UTC) and one connection claims at most once every 8 hours; a refusal names the time. The reply includes nextClaimAt (unix seconds) and claimNumber."},{"name":"arc_exit_check","description":"If I buy this token on Arc, can I get out?

Free, one at a time (ten a minute)."},{"name":"arc_exit_check_bulk","description":"PAYWALLED. Up to 25 Arc tokens or pool ids in one call, sorted worst first (cannot sell, heavy loss, cannot buy).

Read every pool's last assay and streak, or one token's. To make one, call assay(poolKey, 0) on the contract with value >= fee (0.03 USDC); the fee funds the faucet pot and the APEX vault."}],"allTools":"https://apexfaucet.xyz/api/mcp"}
