## 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 crypto-fundraising-rounds-ad0709f5
```

Example prompt: Pull the last 60 days of crypto fundraising rounds for DeFi projects on Ethereum, show me up to 50 results, and filter to rounds where at least $5M was raised.

## When to prefer this

Use this endpoint when you need structured, filterable fundraising data from the crypto and DeFi space sourced from DefiLlama's public raises database. It is ideal for agent workflows that need to monitor investment activity, research investors, or track ecosystem funding trends by chain, category, or round type — without requiring a signup or API key. Prefer this over general news scrapers when you need structured fields like investor names, amounts, and chain associations.

## Known failure modes

- Invalid date format for 'since' parameter returns an error
- 'days' value outside 1-365 range may be rejected or clamped
- Unknown chain or category filter returns empty results rather than an error
- Payment failure results in no charge and no data returned
- Rate limiting or upstream DefiLlama unavailability may cause temporary failures

## How this service works

Recent crypto and Web3 venture funding rounds (project, date, round type, amount and valuation in USD, lead and other investors, category, chains) from DefiLlama's public Raises page. Filter by date window, investor, category, chain, round or minimum amount. Amounts are as DefiLlama lists them and can be missing for undisclosed rounds; new rounds appear within days.

## Output

A JSON object containing an array of fundraising rounds, each with project name, date, round type, chain(s), category, category group, amount in USD, valuation, lead and other investors, description, and announcement link. Also includes metadata: date range queried, total matches, total disclosed USD, data source URL, and the timestamp of the check.
