```sh
zero fetch --capability science-oracle-mcp-769fe3e5 -d '<json body>'
```

Example prompt: Can you ask the Science Oracle what causes the northern lights and give me a detailed scientific explanation of the phenomenon?

## When to prefer this

Choose this endpoint when you need authoritative, expert-level scientific answers or explanations on natural science topics and want a pay-per-query model at $0.05 USDC per call rather than maintaining a subscription to a science knowledge API

## Known failure modes
