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 uniswap-v3-order-book-depth-via-agentdiet-mcp-gateway-876d7f80
```

Example prompt: Can you pull the Uniswap V3 order book depth for the WETH token so I can see how much liquidity is available before I make a large trade?

## When to prefer this

Prefer this endpoint when you need Uniswap V3-specific on-chain liquidity depth data and are comfortable with micropayment-based access via x402/USDC on Base. It is particularly suited for AI agents operating in DeFi contexts that need compressed, deterministic depth snapshots for pre-trade analysis, arbitrage evaluation, or liquidity monitoring, without running their own Uniswap V3 node or subgraph.

## Known failure modes

- Invalid or unrecognized token symbol returns empty or error data
- Token not listed on Uniswap V3 results in no depth data
- Payment failure (insufficient USDC on Base) returns 402 error before data is served
- Network or upstream Uniswap data unavailability causes timeout or empty response
- Malformed query parameters result in schema validation error

## How this service works

Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://mcp-gateway.agentdiet.dev settling in USDC on Base.

## Output

Returns a JSON object with a 'data' field containing the Uniswap V3 liquidity depth information for the requested token, a 'status' field indicating success, and an 'roi_proof' object showing compression efficiency (e.g. compression_ratio_pct of 91.4%), indicating the data has been significantly compressed for efficient delivery.
