## 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 forge-x402-solana-dex-spread-route-quality-f468f171 -d '<json body>'
```

Example prompt: What's the current venue spread in basis points for swapping 100 SOL (mint So11111111111111111111111111111111111111112) to USDC (mint EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v) on Solana right now, and what's the best output I'd get via Jupiter?

## When to prefer this

Choose this endpoint when you need real-time, per-call Solana DEX spread data without committing to a long-term API key subscription — especially useful for autonomous trading agents that need to evaluate route quality before executing swaps, pay-per-use via x402/USDC, and require sub-second Jupiter aggregator data including multi-leg route analysis and venue spread in basis points.

## Known failure modes

- Invalid or unrecognized mint address returns an error or empty route
- Amount set to zero or missing may cause a validation error
- Network congestion on Solana may delay or stale the Jupiter quote
- Payment failure via x402 (insufficient USDC balance) blocks the request
- Token pair with very low liquidity may return extreme spread values or no route

## How this service works

Live Solana DEX data for trading agents: Jupiter route quality, venue spreads in bps, liquidity snapshots, new pairs, trending tokens. Pay per call via x402 with USDC on Base or Solana. No API keys.

## Output

Returns a JSON object with timestamp, number of swap route legs, input mint, output mint, input amount, best output amount, worst leg output amount, and venue spread expressed in basis points — enabling precise assessment of DEX route quality and market tightness before executing a trade.
