}Search open (posted) or upcoming (forecasted) US federal grant opportunities on Grants.gov by keyword, applicant eligibility type, funding category and agency. Returns each grant's title, opportunity number, agency, open and close dates, award floor and ceiling, eligible applicant types and Grants.gov link, sorted by soonest close date by default (among the 30 best keyword matches when a keyword is given). Use when the user wants to find federal grants for an organization, project or topic. Covers federal grants listed on Grants.gov only, not state, local, foundation or corporate grants. Eligibility filtering uses Grants.gov's applicant-type codes; always confirm eligibility with get_grant_details or the full announcement.
| Argument | Type | Description |
|---|---|---|
| sort | string | 'closing_soon' = soonest deadline first among the best keyword matches (default); 'relevance' = best keyword match first; 'newest' = most recently posted first. |
| limit | integer | How many grants to return (1-15). |
| agency | string | Agency code from list_grant_filters, e.g. 'HHS', 'USDA', 'NSF', or a sub-agency code like 'HHS-NIH11'. A top-level code includes all its sub-agencies. |
| status | string | 'posted' = accepting applications now (default); 'forecasted' = announced as coming but not yet open. |
| keyword | string | Topic words to match, e.g. 'rural broadband', 'youth mental health', 'women entrepreneurs'. Leave empty to browse by filters only. |
| category | array | Funding categories to filter by, e.g. ['health'] or ['agriculture','energy']. |
| eligibility | array | Applicant types to filter by, e.g. ['nonprofit_501c3'] or ['small_business']. Grants matching ANY listed type are returned. |
| include_unrestricted | boolean | When filtering by eligibility, also include grants marked 'unrestricted' (open to any entity type). Default true. |
