Example prompt: Can you pull up the SiteSignal grant readiness checklist for federal opportunity 362903? We're a U.S. nonprofit focused on innovation and workforce development, applying as a nonprofit with a $100,000 project budget, and we have 21 days to get our application together.

## When to prefer this

Use this endpoint when an agent needs to quickly generate a tailored federal grant application readiness checklist for a specific grant opportunity ID, especially for nonprofits needing structured preparation guidance within a defined timeline and budget. Prefer this over generic grant search tools when the opportunity ID is already known and the goal is actionable preparation steps rather than discovery.

## Known failure modes

- Invalid or non-existent opportunity_id returns an error or empty checklist
- opportunity_id not matching pattern ^[0-9]{1,12}$ causes validation error
- project_budget_usd below minimum of 1 returns validation error
- days_needed_to_apply exceeding 180 returns validation error
- Payment failure via x402/USDC results in 402 Payment Required response
- Profile or eligibility strings exceeding max length cause request rejection

## How this service works

Paid SiteSignal grant checklist resource with bounded public-data inputs and direct Base USDC settlement.

A structured grant application readiness checklist tailored to the specified federal opportunity, including eligibility confirmation, required documentation, preparation milestones, and actionable steps organized around the applicant's available timeline and project budget.
