## How to call it through Zero

```sh
zero fetch --capability sitesignal-grant-readiness-checklist-b815e758
```

Example prompt: Can you pull up a grant readiness checklist for Grants.gov opportunity 123456789? We're a 501(c)(3) nonprofit with a $250,000 project budget and need at least 30 days to prepare the application.

## When to prefer this

Choose this endpoint when you need a structured, actionable grant application checklist derived directly from a specific Grants.gov opportunity ID. It is ideal for nonprofits, universities, government agencies, or grant writers who want to quickly assess readiness before investing in a full application. Prefer this over generic grant search tools when you already have an opportunity ID and need evidence-linked, checklist-formatted guidance rather than raw grant listings.

## Known failure modes

- Invalid or non-existent opportunity_id (must be 1–12 digits) returns an error
- Opportunity no longer active or past deadline may return incomplete or stale checklist data
- Missing required opportunity_id query parameter returns a validation error
- Opportunity with restricted or non-public data may yield a partial checklist
- Payment failure via x402 protocol results in no response

## How this service works

Turn one Grants.gov opportunity into an evidence-linked application-readiness checklist covering deadline, eligibility, registrations, budget, attachments, and agency contact.

## Output

Returns a structured, evidence-linked checklist organized by category (deadline, eligibility, required registrations, budget considerations, required attachments, and agency contact details), with each item sourced to observable grant documentation so applicants know exactly what they need to do before submitting.
