Allowance check on Arc, before an app asks for an approval: what owner has already approved to spender for a token (default USDC; add &token=0x... for another), in tokens and USD, whether it is unlimited, the owner's balance, whether the spender is a contract and its name if it is one our own code uses on Arc (Uniswap v4 PoolManager, UniversalRouter, Permit2, Circle Gateway Wallet, CCTP TokenMessenger, the launchpad router; never guessed), and risk signals (unlimited to an unknown contract, an…

Count exact LLM tokens for a string using the real OpenAI BPE (o200k_base for gpt-4o/o-series, cl100k_base for gpt-4/gpt-3.5). Deterministic, offline - budget context windows without calling a model.

Arc rug check: holders, dev wallet and liquidity. Holder count, top 10 with % of supply, top 10 wallets without pools, what the v4 pools hold now, and whether the creator took the liquidity back. History proven complete. Rug check for an Arc token: who holds it, how much the top 10 hold, and did the dev (the creator) sell or pull the liquidity? Pass ?token=0x....

Token info for any Arc token, before an app shows it: name, symbol, decimals, total supply, whether it is Circle's USDC / EURC, who launched it and when (the wallet that sent the launch transaction, with its other launches in 30 days; from our index of launchpad launches, never guessed), its Uniswap v4 USDC pool count and the deepest pool's price and liquidity, and plain risk signals (fake USDC name, under 24 h old, no or one thin pool, a high-volume launcher). Pass ?token=0x....

USD price of any Arc token in one call. Pass ?token=0x.... Read live from the Uniswap v4 pool state on Arc mainnet (StateView slot0 + liquidity) across the token's USDC pools from our index of every v4 pool (updated every 5 minutes), the deepest hookless one preferred. Returns usdPrice, the pool used, liquidityUsdEstimate, block, block time and warnings (pool has a hook, thin under $50). A token with no USDC pool, a non-address or a failed read is refused before payment.

Smart contract risk check (Base, Arc): can the owner mint, pause, blacklist, change fees or upgrade the code? What can the people behind this contract do to holders? Pass ?chain=base|arc&address=0x... and we read its bytecode on chain (and the code behind a proxy): mint, pause, blacklist, change fees or taxes, cap wallets, switch trading off, upgrade the code. Plus proxy type, who owns it now (renounced or a live wallet or contract) and basic token data.
