DIU APIdiu.mil ↗
Access the Defense Innovation Unit's catalog of commercial tech solutions prototyped for the DoD. Search by keyword, vendor, portfolio, or technology area.
What is the DIU API?
The DIU Catalog API provides two endpoints to browse and search the Defense Innovation Unit's Commercial Solutions Catalog, exposing 7 structured fields per entry including project_name, vendor_name, portfolio, year_referenced, key_terms, dod_partners, and uuid. Use get_catalog to retrieve the full listing with optional keyword filtering and pagination, or use search_catalog for targeted keyword queries across project names, vendors, portfolios, and technology areas.

Typed, relational, agent-ready
A generated client with real types, enums, and the links between objects — the structure a flat JSON response can't carry. Autocompletes in your editor and reads cleanly to coding agents.

# List all catalog entries with a keyword filter

Retrieve DIU commercial solutions catalog entries with optional keyword filtering. Paginates automatically through results. Each entry represents a prototyped commercial technology solution available to DoD. Without a query, returns all entries; with a query, filters across project names, vendor names, portfolios, and key terms. Results are ordered by year referenced (newest first).
| Param | Type | Description |
|---|---|---|
| limit | integer | Maximum number of results to return. |
| query | string | Search keyword to filter catalog entries across project names, vendor names, portfolios, and key terms. |
| offset | integer | Starting offset for pagination. |

}About the DIU API
Endpoints and Response Shape
The get_catalog endpoint retrieves all entries in the DIU Commercial Solutions Catalog and supports optional query, limit, and offset parameters. It automatically paginates through results up to the specified limit. Each response includes total_records (total matching entries in the catalog), returned_count (how many records came back in this call), and a catalog array of entry objects. Each catalog entry carries a uuid, project_name, vendor_name, portfolio, year_referenced, key_terms, and dod_partners.
Search Behavior
The search_catalog endpoint requires a query string and returns matching entries across project names, vendor names, portfolios, and key terms simultaneously. This makes it useful for finding all entries related to a technology area — for example, passing query: 'AI' returns entries where AI appears in any of those fields. Both endpoints return the same catalog entry shape, so response handling is consistent between them.
Data Coverage
Entries represent commercial technology solutions that have gone through DIU's prototyping process. The dod_partners field identifies which DoD components sponsored or participated in a given project. The portfolio field groups entries by technology domain (for example, space, cyber, human systems), and year_referenced indicates when the solution was cataloged. The key_terms field surfaces technology tags associated with each entry, which is particularly useful for filtering by capability type without knowing exact project or vendor names.
The DIU API is a managed, monitored endpoint for diu.mil — not a raw scraper you maintain. Every endpoint is automatically health-checked on a schedule, and when diu.mil changes and a check fails, the API is automatically queued for repair and re-verified. It is built to keep working as the site underneath it changes.
This isn't an official diu.mil API — it's an independent, maintained REST wrapper over public data. Where the source has no official API (or only a limited one), Parse gives you a stable contract over a source that never promised one, and keeps it current. Need a new endpoint or field? You can revise it yourself in plain English and the agent rebuilds it against the live site in minutes — contributing the change back to the shared API is free.

- Build a searchable directory of DoD-vetted commercial vendors using vendor_name and portfolio fields
- Identify which DoD components (dod_partners) have adopted specific commercial technology categories
- Track year-over-year trends in DIU prototyping by filtering on year_referenced
- Map technology coverage gaps in the catalog by aggregating key_terms across all entries
- Find all catalog entries for a specific technology area (e.g., 'drone', 'cyber') using search_catalog
- Cross-reference DIU solutions with internal procurement records using the uuid field
- Filter catalog entries by portfolio to scope research to a specific DoD technology domain
