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 cambrian-x402-uniswap-v3-pool-data-2954ae3b
```

Example prompt: What's the current state of the Uniswap V3 USDC/ETH 0.05% fee pool on Ethereum mainnet — give me the liquidity, current tick, and token addresses?

## When to prefer this

Choose this endpoint when you need pay-per-use, agent-friendly access to Uniswap V3 pool data on EVM chains without managing your own RPC infrastructure. It is ideal for autonomous agents that need micropayment-native blockchain data access via the x402 protocol, avoiding API key management. Prefer it over self-hosted solutions when low-overhead, on-demand DeFi data retrieval is needed for trading bots, arbitrage agents, or liquidity monitoring systems.

## Known failure modes

- Payment not provided or insufficient USDC — returns HTTP 402 requiring x402 payment
- Invalid or unsupported query parameters — returns empty array or error
- Pool address or token pair not found on the specified chain — returns empty result
- Unsupported EVM chain — endpoint may return error or empty response
- Network timeout or RPC node unavailability — transient 5xx errors

## How this service works

Pay-per-use blockchain and social data for autonomous agents.

## Output

Returns an array of Uniswap V3 pool records containing pool state data such as token addresses, fee tier, current liquidity, current tick, square root price, and related on-chain pool parameters for the queried EVM network.
