## How to call it through Zero

```sh
zero fetch --capability trader-rigoblock-com-412323b2
```

Example prompt: What's the current Uniswap price quote for swapping ETH to USDC on Arbitrum right now?

## When to prefer this

Use this endpoint when you need real-time on-chain DEX price quotes from Uniswap across multiple EVM chains, especially when validating swap prices against an oracle (e.g. for Rigoblock Swap Shield comparisons) or when you need multi-chain price coverage in a single API. Prefer this over centralized price APIs when on-chain accuracy and DEX-specific pricing are required.

## Known failure modes

- Unsupported token pair — no liquidity pool found on the requested chain
- Unsupported chain — only Ethereum, Base, Arbitrum, Optimism, Polygon, BNB, and Unichain are supported
- Missing required query parameters returns a 400 error
- Payment not provided or insufficient — x402 payment required ($0.002 USDC per call)
- Stale or unavailable oracle data for low-liquidity tokens

## How this service works

DEX price quote across 7 chains (Ethereum, Base, Arbitrum, Optimism, Polygon, BNB, Unichain). Returns sell/buy amounts, price, routing, and gas estimate.

## Output

Returns a real-time DEX price quote sourced from Uniswap liquidity pools for the requested token pair on the specified chain, suitable for swap price comparison and oracle validation.
