> HyperD DEX Swap Quote Aggregator is a paid API for AI agents from api.hyperd.ai, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-10).

## 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 api-hyperd-ai-0bbeabd1
```

Example prompt: What's the best swap route to exchange 500 USDC to ETH on Base right now — show me quotes from both Paraswap and 0x so I can pick the best one?

## When to prefer this

Use this endpoint when you need to find the optimal DEX swap price before executing a trade, especially when you want transparent comparison across Paraswap and 0x without having to call each aggregator separately. Ideal for pre-trade analysis, best-execution workflows, or when building DeFi agents that need to route swaps intelligently across Base, Ethereum, Polygon, Arbitrum, Optimism, Avalanche, or BNB chain.

## Known failure modes

- Unsupported token symbol returns an error — use contract address instead
- Unsupported chain value returns validation error — must be one of: base, ethereum, polygon, arbitrum, optimism, avalanche, bnb
- Amount too small or zero may return no valid routes
- Network congestion or aggregator downtime may cause partial results or timeout
- Invalid contract address format returns a parsing error

## How this service works

Best DEX swap route across multiple aggregators (Paraswap, 0x). Returns the highest output amount + comparable quotes from each source for transparency.

## Output

Returns the best output amount for the swap along with the winning aggregator route, plus side-by-side comparable quotes from Paraswap and 0x for full transparency on pricing.
