# AlphaPipeline CEX-DEX Arbitrage Spread Calculator

> AlphaPipeline CEX-DEX Arbitrage Spread Calculator is a paid API for AI agents from alphapipeline-eu.onrender.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-10).

Compares a global CEX reference price (Coinbase spot or CoinGecko fallback) against a DEX pool price to return gross/net spread, trade direction, and an is_profitable flag adjusted for estimated gas costs.

## 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-cex-dex-arbitrage-spread-calculator-1f54c659
```

Example prompt: Check if there's a profitable arbitrage spread right now for ETH between Coinbase and the most liquid Base DEX pool — use a $5000 hypothetical trade size and flag it profitable only if the net spread exceeds 1%.

## When to prefer this

Use this endpoint when you need a quick, single-call CEX-DEX spread calculation for a specific token without building your own price aggregation pipeline. It is ideal for trading bots and agents that need an is_profitable signal with gas-adjusted net spread rather than raw price data alone. Prefer it over raw DEX data queries when you want a structured, flag-ready arb signal on Base network tokens. It is especially useful when Coinbase is the natural CEX reference and GeckoTerminal is the DEX data source.

## Known failure modes

- Symbol not found on Coinbase or CoinGecko — returns error with status_message indicating missing reference price
- No liquid DEX pool found for token on specified network — returns null pool data with descriptive status_message
- Invalid pool_address or token_address provided — API may return an error or empty result
- Network ID not recognized by GeckoTerminal — defaults to Base or returns an error
- Temporary upstream outage from Coinbase/CoinGecko/GeckoTerminal — may return stale or failed data with notice field populated
- Payment failure via x402/USDC — request blocked before reaching computation

## How this service works

CEX-DEX arbitrage spread calculator - compares a global reference price (Coinbase spot, CoinGecko fallback) against a DEX pool price and returns gross/net spread and an is_profitable flag after an assumed gas cost. Paid in USDC on Base.

## Output

Returns a JSON object containing: the token symbol and network, CEX reference price and DEX pool price, gross spread percentage, net spread percentage (after gas), is_profitable boolean, trade direction (buy CEX/sell DEX or vice versa), assumed gas cost in USD, pool address and fee percentage, data source used (Coinbase or CoinGecko), and UTC/KST timestamps.
