# AlphaPipeline DEX Slippage

> AlphaPipeline DEX Slippage is a paid API for AI agents from alphapipeline-eu.onrender.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).

Estimates trade slippage and retrieves pool liquidity data for a given DEX pool on a specified network using GeckoTerminal data, based on a constant-product approximation model.

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 alphapipeline-dex-slippage-525302bd
```

Example prompt: Before I swap, can you check what the estimated slippage would be on a $5,000 trade for the token at 0x4200000000000000000000000000000000000006 on the Base network?

## When to prefer this

Use this endpoint when you need a quick pre-trade slippage estimate for a DEX swap on Base or Ethereum without executing any transaction. It is ideal for agents doing trade routing, size optimization, or pool comparison before committing to a swap. Prefer this over on-chain simulation when you need a fast, low-cost approximation and can accept the constant-product model caveat. Not suited for real-time execution or for pools with complex AMM curves (e.g. Curve or concentrated liquidity).

## Known failure modes

- Invalid or unsupported network ID returns an error
- Pool address not found on specified network
- Neither pool_address nor token_address provided returns a validation error
- Token with no liquid pools on the specified network returns null liquidity fields
- GeckoTerminal data unavailable or rate-limited causes upstream failure
- trade_size_usd missing triggers required field validation error

## How this service works

GeckoTerminal-backed DEX pool liquidity and estimated trade slippage - size a trade or compare pools before swapping, with a clearly-flagged constant-product approximation model.

## Output

Returns the estimated slippage percentage and pool liquidity details including pool name, pool address, liquidity in USD, 24-hour trading volume, trade size used for estimation, the price impact model used (constant-product approximation, clearly flagged), data source attribution, and generation timestamps in UTC and KST.
