How this service works
Pay-per-call market math and token intel for AI agents, via x402.
Output
Returns a JSON object containing: a trade quote (amount in/out with units, price impact %), market data (USD price, liquidity), a risk assessment (score 0-100, label, flags), a verdict string (e.g. 'caution'), any warnings, and a disclaimer. The verdict summarizes whether the trade looks safe to proceed.
Example use cases
Pre-trade risk check on new token
“I'm about to ape into this new Base token at 0xabc123... — can you check it first and tell me the risk score, any red flags, and what verdict the market math gives before I pull the trigger?”
Simulate sell impact for large position
“I hold 50000 units of the token at 0xdef456... on Ethereum and want to sell — how much price impact will that cause with a 1% fee, and what do I actually get out in the quote token?”
Agent pre-swap safety gate
“Before my trading agent executes any swap, run a precheck on the Solana token at address So11...1112 with a buy side and 0.25 SOL in — only proceed if the risk label comes back low and price impact is under 3%.”
Technical details
Endpoint
GEThttps://curvecall.onrender.com/v1/precheck/%7Bchain%7D/%7Baddress%7D?utm_source=zero.xyzWhen to prefer
Use CurveCall's precheck endpoint when an AI agent needs to gate a token swap on risk and price-impact math before execution — especially in autonomous trading workflows where you want a structured risk verdict (score, label, flags) alongside a trade quote in a single call. Prefer this over generic DEX aggregator APIs when you need the risk assessment bundled with the quote, and over static token scanners when you need live price-impact simulation for a specific trade size.
Side effects
- Invalid or unsupported chain ID returns an error — use Dexscreener-compatible IDs like 'base', 'solana', 'ethereum'
- Unknown or unindexed token contract address may return no market data
- Insufficient liquidity for the requested amount_in may produce extreme price impact values
- Payment failure via x402 protocol blocks the call before execution
- Malformed address format returns a validation error
