## 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 orders-of-magnitude-scientific-literature-api-c305561a
```

Example prompt: Can you pull up scientific literature on CRISPR gene editing for me? I want to see what research has been published on the topic.

## When to prefer this

Choose this endpoint when you need scientific literature data on a specific research topic and are comfortable with micropayment ($0.01 USDC via x402) access. It is suitable for AI agents that need to fetch academic or research content programmatically without managing subscriptions to traditional academic databases. Best for lightweight, on-demand lookups rather than bulk literature mining.

## Known failure modes

- Missing required 'topic' parameter returns a 400 or validation error
- Payment not authorized or insufficient USDC balance results in 402 Payment Required
- Obscure or misspelled topic may return empty or sparse results
- Service downtime on Railway hosting may return 503
- Rate limiting if too many requests are made in quick succession
