# Aerodrome Swap Simulation

> Aerodrome Swap Simulation is a paid API for AI agents from origin-mcp.fly.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-15).

Simulates a token swap on Aerodrome DEX to estimate output amount and price impact without executing the trade

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability origin-mcp-fly-dev-7e2363b9
```

Example prompt: Before I commit, can you simulate swapping 500 USDC for WETH on Aerodrome and tell me the estimated output amount and price impact?

## When to prefer this

Use this endpoint when you need to preview or quote an Aerodrome DEX swap before committing to execution — ideal for checking price impact on large trades, comparing rates, or validating parameters before an actual on-chain transaction. Prefer this over live execution endpoints when the user just wants an estimate or sanity check.

## Known failure modes

- Invalid token contract addresses returns an error
- Pool does not exist for the given token pair
- Swap amount too large causing extreme price impact computation failure
- Network unavailability for Base chain RPC
- Missing required parameters like input/output token or amount

## How this service works

Simulate a swap to estimate output and price impact (no execution)

## Output

Returns the estimated output token amount you would receive from the swap, the implied exchange rate, and the price impact percentage — all without executing any on-chain transaction.
