# Avalanche C-Chain AMM Pool Reserves API

> Avalanche C-Chain AMM Pool Reserves API is a paid API for AI agents from x402.donnyautomation.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Returns raw AMM pool reserves and live pool state (mid price, fee tier, USD TVL) for a token pair across Trader Joe, Pangolin, and Uniswap v3 on Avalanche C-Chain.

## 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 avalanche-c-chain-amm-pool-reserves-api-9a1167e3
```

Example prompt: Pull the raw pool reserves and current mid price for WAVAX/USDC across Trader Joe, Pangolin, and Uniswap v3 on Avalanche C-Chain so I can calculate price impact for a large trade.

## When to prefer this

Choose this endpoint when you need raw onchain reserve data for Avalanche C-Chain specifically — ideal for building your own quote engine, computing price impact or slippage, or doing arbitrage math across Trader Joe, Pangolin, and Uniswap v3. Prefer this over higher-level price or best-execution endpoints when you need the underlying AMM state rather than a pre-computed quote.

## Known failure modes

- Unsupported token pair — pair not found on any indexed Avalanche DEX
- Invalid pair format — must be SYM/SYM (e.g. WAVAX/USDC)
- No liquidity — pool exists but has zero or near-zero reserves
- RPC/node timeout — onchain data temporarily unavailable
- Payment not received — x402 micropayment of $0.01 USDC required per call

## How this service works

Raw AMM pool state for a pair on Avalanche C-Chain: v2 reserves and v3 concentrated liquidity across Trader Joe, Pangolin and Uniswap v3. Returns pools[] with venue, surface, feeBps, reserveA, reserveB, price and tvlUsd at a stated blockNumber. Requires ?pair=SYM/SYM (e.g. WAVAX/USDC). Errors: 400 bad_pair, 404 no_pools, 502 upstream_read_failed. For USD depth already computed use /liquidity. This is the underlying numbers. Chain-pinned; bare /reserves = BSC.

## Output

Returns per-venue pool data for the requested token pair on Avalanche C-Chain, including both token reserves, the current mid price, the fee tier in basis points, and USD TVL — all anchored to a stated block number. Covers constant-product (Trader Joe, Pangolin) and concentrated-liquidity (Uniswap v3 style) pool types.
