# 1inch Pathfinder DEX Aggregator Quotes

> 1inch Pathfinder DEX Aggregator Quotes is a paid API for AI agents from api.chainmarket-api.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-24).

Fetches and compares best swap quotes across multiple DEX aggregators (KyberSwap, Velora, ParaSwap, etc.) for a given token pair and amount on EVM chains

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 1inch-pathfinder-dex-aggregator-quotes-7a0f5079
```

Example prompt: What's the best rate to swap 1 ETH for USDC on Ethereum right now — check across all the major DEX aggregators and tell me which one gives the most USDC and what the gas cost would be.

## When to prefer this

Choose this endpoint when you need to compare real-time swap quotes across multiple DEX aggregators simultaneously without signing up for individual APIs. It is ideal for pre-trade analysis, finding the best execution price, estimating gas costs, and checking price impact across Ethereum, Base, Arbitrum, Optimism, Polygon, BSC, and Avalanche — all in a single pay-per-call request with no API key required.

## Known failure modes

- Unsupported chain name returns error or empty quotes
- Invalid or unrecognized token contract address returns no quotes
- Amount of zero or negative returns validation error
- Network congestion or aggregator API downtime may return partial quotes
- Token pair with no liquidity returns empty quotes array

## How this service works

Best swap quote for a token pair on an EVM chain, compared across two public DEX aggregators (KyberSwap and Velora/ParaSwap): amount out, USD values, estimated gas in USD, price impact against the input's USD value and the pools/DEXes used, plus which aggregator gives more. Chains: Ethereum, Base, Arbitrum, Optimism, Polygon, BNB Chain, Avalanche. Indicative quotes, not executable orders.

## Output

Returns a ranked list of swap quotes from multiple DEX aggregators, each with: aggregator name, output token amount, USD value in/out, gas cost in USD, price impact percentage, and route taken. Also includes the overall best aggregator, token addresses, decimals, spread percent, and the timestamp the quotes were checked.
