## 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 allthebot-base-swap-quote-503d8df6
```

Example prompt: What's the best price I can get to swap 1 ETH for USDC on Base right now — check Uniswap v3 and Aerodrome and tell me which DEX gives the most USDC?

## When to prefer this

Use this endpoint when you need the best available on-chain swap price on Base network without executing a trade. It aggregates multiple DEX sources (Uniswap v3 all fee tiers + Aerodrome stable/volatile) in a single call, saving the agent from querying each DEX separately. Prefer this over single-DEX quote APIs when price optimization matters, or when building a DeFi workflow that needs to pre-check rates before committing a transaction. Not suitable if you need quotes on Ethereum mainnet, other L2s, or need to actually execute the swap.

## Known failure modes

- Unsupported token pair returns no quotes or empty result
- Invalid token symbol or address returns an error
- amount_in format not matching numeric pattern causes validation error
- No liquidity available for pair results in empty or zero quotes
- Network congestion or RPC issues may cause stale or failed quote fetches
- Payment of $0.0025 USDC required per call via x402 protocol; missing payment returns 402

## How this service works

Best swap price on Base (DEX quote aggregator): live quotes from Uniswap v3 (all fee tiers) and Aerodrome (stable/volatile) for any ERC-20 pair, ranked best first. Symbols ETH, USDC, cbBTC, DAI or token addresses. Read-only, no swap executed.

## Output

A ranked list of swap quotes from Uniswap v3 (across all fee tiers: 0.01%, 0.05%, 0.3%, 1%) and Aerodrome (stable and volatile pools), showing the expected output amount for each route, sorted best-first so the agent can immediately identify the optimal DEX and pool for the trade. No swap is executed — this is a read-only price check.
