Search Grants & Contracts (Combined)
search_grants_and_procurementRead-onlyIdempotent
MIXED search across all 35,264 opportunities from 231 sources — combines grants AND procurement/contracts in one query. This mixes funding types which can create noisy results.
ROUTING — use the specialized tool instead: • User wants grants/funding/fellowships/prizes → search_grantsplus • User wants contracts/RFPs/procurement/bids → search_procurement • User explicitly wants BOTH types → search_grants_and_procurement • Intent unclear → ASK the user first
Use search_grantsplus or search_procurement for cleaner, more relevant results. Free tier: 10 searches/month, full results. Paid plans add higher monthly limits. Paid plans show new listings the day they open; the free plan reaches the same listings after 10 days. Counts toward your monthly searches.
Input Schema
TableJSON Schema
| Name | Required | Description | Default |
|---|---|---|---|
| limit | No | Max results (default: 10) | |
| query | No | Natural language search query | |
| since | No | Stateless alternative to posted_within_days/new_within_days: ISO 8601 instant. Only opportunities ingested at/after this instant. Store the previous response newSince.newest and pass it here to manage your own watermark. | |
| cursor | No | Pagination cursor from previous response | |
| source | No | Filter by source domain or dataSource (e.g., "grants.gov" or "tier0-sam.gov") | |
| status | No | Filter by status | |
| compact | No | Return compact results (default: true). Compact results include essential fields: id, title, organization, category, url, deadline, deadlineType, daysUntilDeadline, deadlineLabel, lastRoundClosedAt, status, qualityScore, and snippet. Set to false for full details including eligibility, amounts, and match explanations. | |
| category | No | Filter by category | |
| min_quality | No | Minimum quality threshold (default: medium) | |
| organization | No | Filter by organization or funder name | |
| user_context | No | User context for better filtering | |
| new_within_days | No | Backwards-compatible alias for posted_within_days. Only opportunities WE ADDED (ingested) in the last N days for recurring/delta checks ("what is new since my last check"). Additive to all other filters. In queryless browse mode without a single source, the recency window is sampled across sources round-robin by ingest recency so one bulk harvester cannot own the digest; each source remains newest first. The response includes newSince and windowCoverage: sourcesSampled counts distinct sources returned by the grouped provider query before MCP quality, judge, recency-withhold, and page filters; it is absent when no grouped sample was available, including when sampling was not attempted, and 0 means the grouped query succeeded but returned no sourced rows; sourcesServed counts distinct sources delivered on this page. windowCoverage.order is "recency" for the queryless browse digest or "relevance" when a query is present. windowIncomplete/incompleteReason is separate from ceilingTruncated, which is true only when the 2,000-row ceiling excluded records; ceilingTruncated and hardCeiling are present only when order is "recency" and are omitted entirely under "relevance" (query mode never walks past a single bounded fetch, so no ceiling logic runs). Not the opportunity posted date or deadline. | |
| procurement_type | No | Filter SAM.gov contracts by industry type. professional_services = consulting, engineering, R&D (NAICS 54xxxx, excludes manufacturing/construction noise). it_services = software, IT systems (NAICS 5415xx). construction = building projects (NAICS 23xxxx). manufacturing = production (NAICS 31-33xxxx). Use this to avoid irrelevant commodity results like "O-RING" or "VALVE" when searching for service contracts. | |
| posted_within_days | No | Preferred alias for new_within_days: only opportunities WE ADDED (ingested) in the last N days. In queryless browse mode without a single source, the recency window is sampled across sources round-robin by ingest recency so one bulk harvester cannot own the digest; each source remains newest first. In windowCoverage, sourcesSampled counts distinct sources returned by the grouped provider query before MCP quality, judge, recency-withhold, and page filters; it is absent when no grouped sample was available, including when sampling was not attempted, and 0 means the grouped query succeeded but returned no sourced rows; sourcesServed counts distinct sources delivered on this page. windowCoverage.order is "recency" for the queryless browse digest or "relevance" when a query is present. windowIncomplete/incompleteReason is separate from ceilingTruncated, which is true only when the 2,000-row ceiling excluded records; ceilingTruncated and hardCeiling are present only when order is "recency" and are omitted entirely under "relevance" (query mode never walks past a single bounded fetch, so no ceiling logic runs). Uses the same ingest freshness field as newSince/recurring checks; not the opportunity posted date or deadline. If both posted_within_days and new_within_days are supplied, posted_within_days wins. | |
| deadline_within_days | No | Only opportunities closing within N days |
