Defense Contract Audit Agency

The Defense Contract Audit Agency (DCAA), under the authority, direction, and control of the Under Secretary of Defense (Comptroller), provides audit and financial advisory services to the Department of Defense and other federal entities responsible for acquisition and contract administration. DCAA runs no developer program: no API documentation, no OpenAPI, no SDK, no MCP server, no agent card and no /.well-known surface exist on any host it operates. It does serve one public, unauthenticated and undocumented JSON API — the Field Audit Office Branch Locator at https://fao.dcaa.mil/api — which resolves the cognizant DCAA audit office for a contractor by CAGE code, SAM.gov UEI or ZIP code and returns RFC 9457 problem details on validation failure. A second, gated surface, the Contractor Submission Portal at https://csp.dcaa.mil, takes certified incurred cost submissions behind an OpenID Connect sign-in federated to DoD PIEE.

Defense Contract Audit Agency publishes 2 APIs on the APIs.io network. Tagged areas include Federal-Government, Defense, Department of Defense, Audit, and Contract Audit.

Defense Contract Audit Agency’s developer surface includes authentication, support, and 15 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Government & Public Sector regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/defense-contract-audit-agency: open an issue to ask a question, or submit a pull request to add artifacts.

  name: DCAA Field Audit Office Branch Locator API
  description: 'The public JSON backend of DCAA''s Field Audit Office Branch Locator. It resolves the DCAA field audit office
    cognizant over a contractor from a CAGE code (searchType 0), a SAM.gov Unique Entity Identifier (searchType 1) or a US
    ZIP code (searchType 2), returning the branch name, phone, email and address along with region information. Three companion
    endpoints publish the regular expressions the API validates each identifier against, and two more publish the current
    service notice. Everything is anonymous, read-only and free. DCAA publishes NO specification, NO documentation and NO
    terms for it — this entry was established by live probing on 2026-09-07 (six operations observed returning HTTP 200/400/404),
    which is why no OpenAPI pointer is wired: none exists, and authoring one would credit DCAA with a contract it has never
    published. Validation failures return RFC 9457 application/problem+json with a W3C trace-context traceId.'

  description: The portal a defense contractor uses to file, update or withdraw a certified incurred cost submission with
    DCAA. It is a DCAA-operated application on a DCAA host, but every path redirects unauthenticated callers to the DoD Procurement
    Integrated Enterprise Environment (PIEE) authorization endpoint — OAuth 2.0 authorization code with PKCE (S256), client_id
    csp, scopes openid and profile. Access requires a DoD PIEE account, not a developer credential. No API, no specification
    and no machine-readable contract are published for it; it is recorded here because it is the agency's only write surface
    and its authentication model is observable. Listed as gated, not as a callable API.
