## How to call it through Zero

```sh
zero fetch --capability api-usenami-io-f737716e
```

Example prompt: Can you pull the oracle price-source family classification for all perp venues on Nami so I can see which exchanges share the same oracle and understand my basis risk before running a cross-venue funding arb strategy?

## When to prefer this

Use this endpoint when building cross-venue perpetual futures strategies where oracle-driven basis risk matters — specifically when you need to know whether two or more venues reference the same price source family and might converge or diverge together. Prefer this over generic venue-info endpoints when oracle dependency analysis is the primary concern.

## Known failure modes

- Missing or invalid 'type' or 'method' fields in input returns a 400 validation error
- Payment not provided or insufficient results in 402 Payment Required
- Service temporarily unavailable returns 503
- Stale oracle classification data if venue oracle sources change without cache refresh
- Unknown venue or oracle type not yet indexed returns incomplete results

## How this service works

Oracle price-source family classification across tracked crypto perp venues — which venues derive their index price from the same upstream feed. Basis-risk awareness for cross-venue and funding-arb strategies: two venues sharing an oracle family will not diverge independently, so a spread between them is not the hedge it looks like.

## Output

A structured mapping of 30+ perpetual futures venues to their oracle price-source families, indicating which venues share the same underlying price feed — enabling traders to identify correlated basis risk and group venues by oracle type for cross-venue strategy construction.
