## 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 onchainpulse-institutional-activity-monitor-54e0146c
```

Example prompt: Give me this week's institutional onchain activity brief — I want the latest on tokenization, regulatory, and infrastructure developments from OnchainPulse.

## When to prefer this

Use this endpoint when you need a curated, high-level institutional-grade summary of what is happening in the onchain space — tokenization, regulation, and infrastructure — rather than raw market data or real-time prices. Best for periodic briefings and staying current on macro institutional trends.

## Known failure modes

- No data available for the requested period — returns empty or partial brief
- Payment of 0.1 USDC not processed — returns 402 payment required
- Service temporarily unavailable — 503 error
- Rate limiting if called too frequently

## How this service works

Weekly and monthly institutional onchain-activity brief — tokenization, regulation and infrastructure developments. For institutional and research agents.

## Output

A structured weekly or monthly brief covering institutional onchain activity, including tokenization milestones, regulatory updates across jurisdictions, and blockchain infrastructure developments relevant to institutional participants.
