## 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 agentfeeds-jp-aero-usdc-cross-venue-spread-statistics-8cd998ea
```

Example prompt: Pull me the last 200 AERO/USDC cross-venue spread records from agentfeeds, comparing Aerodrome's vAMM pool against the Uniswap v3 0.3% pool on Base, going back to 2024-11-01T00:00:00Z.

## When to prefer this

Use this endpoint specifically when you need cross-venue spread analysis for AERO/USDC on Base, comparing Aerodrome's native vAMM pool against a Uniswap v3 0.3% pool. Prefer this over the generic dex.spread_summary endpoint when the focus is specifically on Aerodrome's governance token (AERO). Best for arbitrage monitoring, liquidity analysis, or on-chain market microstructure research on Base.

## Known failure modes

- Invalid 'limit' value outside 1-500 range returns validation error
- Malformed 'since' ISO timestamp returns 400 bad request
- No data available for the requested time range returns empty result set
- x402 payment failure or insufficient USDC balance blocks the request
- Rate limiting if too many calls are made in a short window

## How this service works

1-minute cross-venue spread statistics (bps) for AERO/USDC on Base: Aerodrome's own vAMM pool vs its Uniswap v3 0.3% pool (on-chain mids). Same methodology as dex.spread_summary, dedicated to Aerodrome's own governance token. Descriptive statistics only; not investment advice.

## Output

Returns paginated descriptive statistics of 1-minute spread measurements in basis points for AERO/USDC, comparing mid prices from Aerodrome's native vAMM pool versus its Uniswap v3 0.3% pool on Base. Includes statistical summaries (e.g. mean, min, max, percentiles) of the cross-venue spread. Supports filtering by timestamp and result count.
