## How to call it through Zero

```sh
zero fetch --capability toolhund-market-pulse-e15cedf3
```

Example prompt: Pull the ToolHund Market Pulse feed and tell me which AI tools have changed their pricing or plans in the last 7 days — I want to know the tool name, what changed, and when it happened.

## When to prefer this

Choose this endpoint when you need a real-time, curated feed of AI tool market events — especially pricing changes — aggregated across many tools in a single call. Prefer it over manually scraping individual tool pricing pages, or when building automated market intelligence pipelines that need structured event data with timestamps and source URLs. Best for founders, product teams, or AI agents that need to stay current on the AI software landscape without manually monitoring dozens of vendor sites.

## Known failure modes

- Payment not provided or invalid — endpoint returns 402 requiring x402 USDC micropayment
- No events in the 7-day window — data array may be empty
- Rate limiting if called too frequently — may return 429
- Invalid query parameters may result in 400 bad request
- Source URL may be unavailable if the underlying tool's pricing page has moved

## How this service works

Compare AI tools by pricing, use case, alternatives and score. ToolHund helps founders, CEOs, teams and AI agents choose the right AI software faster.

## Output
