Pre-Trade Token Check is a paid API for AI agents from chain.tollkit.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-12).
Fetches on-chain token facts, current price, wallet position, pool depth, and trade impact estimate before executing a trade on Base, Ethereum, or Solana.
Wallet balances, tokens, transactions and prices on Base, Ethereum and Solana. Other Tollkit tools are described at: https://extract.tollkit.dev/openapi.json, https://attest.tollkit.dev/openapi.json, https://web.tollkit.dev/openapi.json, https://data.tollkit.dev/openapi.json.
Returns a JSON object with the token's name, symbol, decimals, current USD price, total supply, mint and freeze authority status, pool depth in USD, a trade size analysis (flag, price impact percentage, share of pool), your wallet's current position if provided, a list of warnings, a warning count, recent news headlines with URLs, a note that data is factual not advisory, the explorer URL, and the price source details (DEX, pool, fee tier, quote token).
POSThttps://chain.tollkit.dev/chain/pretrade?utm_source=zero.xyzUse this endpoint when an agent needs a comprehensive pre-trade snapshot for a specific token — combining price, pool depth, trade impact, wallet position, on-chain safety signals (mint/freeze authority), and recent news in a single call. Prefer this over the Token Safety Check endpoint when you also need trade sizing analysis and pool depth, and over the Token Info endpoint when you need wallet-specific position data and impact estimation. Ideal for DeFi trading agents that need a go/no-go data bundle before executing a swap.
