## 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 agenticfi-swap-quote-bd54b981
```

Example prompt: What's the best swap quote to trade 0.001 WETH (0x4200000000000000000000000000000000000006) on Base (chain 8453) for USDC (0x833589fCD6EDB6E08f4c7C32D4f71b54bdA02913) also on Base, sending from my wallet 0x742d35Cc6634C0532925a3b844Bc454e4438f44e?

## When to prefer this

Use this endpoint when an AI agent needs to compute how much of a destination token a user will receive before committing to a swap, especially for cross-chain routes or Base ecosystem trades. Prefer this over on-chain simulation when you need fast, pre-trade pricing and routing without gas costs. Best for agents building DeFi workflows that require a quote step before execution.

## Known failure modes

- Invalid token address returns 400 bad request
- Unsupported chain ID returns error indicating chain not supported
- fromAmount of zero or negative value causes validation failure
- Liquidity unavailable for the requested pair returns no route found
- Payment not included or insufficient triggers x402 payment required response
- Rate limiting if too many calls are made without payment

## How this service works

DeFi APIs for AI agents. 36 pay-per-call endpoints for token data, pricing, wallet analytics, swap routing, and on-chain workflows. Powered by x402 on Base.

## Output

Returns a swap quote object containing the expected output token amount, routing path, estimated fees, price impact, and any slippage details for the requested token pair and amount across the specified chains
