## 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-spread-route-quality-baa45d48 -d '<json body>'
```

Example prompt: What's the current venue spread in basis points for swapping 100 SOL (mint So11111111111111111111111111111111111111112) to USDC (mint EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v), and is the Jupiter route quality good right now — amount is 100000000 raw units?

## When to prefer this

Use this endpoint when you need real-time Solana DEX spread and route quality data for a specific token pair before executing a swap, or when monitoring market microstructure on Solana. It is ideal for trading agents that need pay-per-call pricing without API key management. Prefer this over generic price feeds when you specifically need venue spread in basis points and multi-leg route comparison via Jupiter.

## Known failure modes

- Invalid or unknown mint address returns an error or empty route
- Illiquid token pairs may return no route or extremely high spread values
- Very large amounts may fail if liquidity is insufficient for the requested size
- Stale data if Jupiter aggregator is temporarily unavailable
- Payment failure via x402 if USDC balance on Base or Solana is insufficient

## 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 a timestamp, number of route legs, input amount, input and output mint addresses, best output amount, worst single-leg output amount, and the venue spread in basis points (e.g. 3.46 bps for SOL/USDC). The spread value indicates the cost of routing across DEX venues on Solana.
