How this service works
What a trade size actually executes at on Avalanche C-Chain, simulated against live reserves. Returns best (venue, amountOut, executionPrice, priceImpactBps, feeBps, totalCostBps), routingGain, venues[]. Requires ?pair=SYM/SYM AND ?amountUsd=25000 (or ?amountIn=). pair alone = 400 missing_amount. Errors: 400 bad_pair|missing_amount|bad_amount, 404 no_pools|no_quote|cannot_size_in_usd, 502 upstream_read_failed. Spot price without a size is /price. Chain-pinned; bare /slippage = BSC.
Output
Returns the best execution venue (Trader Joe, Pangolin, or Uniswap v3), the actual amount out for the trade size, price impact expressed in basis points, the pool fee separately, and the savings from optimal routing versus simply picking the best-quoted price — all computed against live on-chain reserves.
Example use cases
Pre-trade slippage check for trading bot
“I'm about to execute a large WAVAX/USDC swap on Avalanche — can you simulate it and tell me the price impact in bps, the actual amount out, and which of Trader Joe, Pangolin, or Uniswap v3 gives me the best fill?”
DEX aggregator venue selection
“My aggregator needs to route a JOE/WAVAX trade on Avalanche — simulate the swap across all available venues and tell me which one gives the best execution and by how much compared to just picking the cheapest quoted price.”
Thin market impact assessment
“I want to know if the USDC/WAVAX pool on Avalanche C-Chain is deep enough for my trade size — can you show me the price impact in basis points and the real output amount so I can decide whether to split the order?”
Technical details
Endpoint
GEThttps://x402.donnyautomation.com/avalanche/slippageWhen to prefer
Choose this endpoint when you need pre-trade execution simulation specifically on Avalanche C-Chain, want multi-venue comparison across Trader Joe, Pangolin, and Uniswap v3, and need price impact in basis points plus pool fee broken out separately — especially for trading bots or DEX aggregators that need to validate routing before committing a transaction. Prefer over generic spot-price endpoints when actual execution quality (not just mid-price) is required.
Side effects
- Invalid or unrecognized token pair symbol returns an error
- Pair not listed on any supported Avalanche DEX returns no venue data
- Network congestion or RPC latency may cause stale reserve reads
- Unsupported token contract address format causes parsing failure
- Payment failure (x402) blocks the response if USDC balance is insufficient
