## 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 grantpulse-foundation-grant-intelligence-8a427d8d
```

Example prompt: Find me private, family, and corporate foundation grants for our environmental justice nonprofit — we need LOI strategy and cultivation approach guidance for foundations likely to fund grassroots community organizations.

## When to prefer this

Use this endpoint when specifically seeking private, family, or corporate foundation funding — as opposed to federal grants (use federal grant search) or state programs (use state grant endpoint). Best for nonprofit grant writers needing not just a list of funders but also actionable relationship-building strategy including LOI tips and cultivation approaches.

## Known failure modes

- No matching foundations found for given criteria — returns empty results
- Overly broad query returns too many results with low relevance
- Foundation data may not reflect real-time open cycles or recent program changes
- Payment failure via x402 protocol results in 402 response with no data

## How this service works

Grant discovery and application intelligence API, plus IRS Form 990-based nonprofit/funder financial intelligence. 12 endpoints powered by Grants.gov, USASpending.gov, live IRS public records (EO Business Master File + SOI Form 990/990-PF Annual Extracts), and Claude. All endpoints require x402 payment (USDC on Base mainnet). Flagship match endpoint includes Instrumentl, Grants.gov, and Candid Foundation Directory tool links. Grant writer endpoint includes writing tool links + Amazon grant writing books.

## Output

A curated list of private, family, and corporate foundation funding opportunities relevant to the organization's mission, along with LOI (Letter of Intent) strategy guidance and cultivation approach recommendations for each foundation.
