# Sourceory - full agent reference Sourceory determines whether a project's bill of materials meets the Build America, Buy America (BABA) domestic-content standards for the funding agency, line by line: iron and steel, manufactured products at the 55 percent component-cost threshold, and construction materials. Every verdict cites the OMB or agency source behind it, and where we hold no guidance for an agency we say so rather than reporting a pass. The free calculator runs entirely in your browser, so bill-of-materials data is never transmitted. The same engine is a single-key JSON API and an MCP server, so estimating and bid software, and autonomous compliance agents, can run a determination mid-task. Ruleset generated: 2026-08-02T00:00:00Z. Determinations apply the OMB M-24-02 methodology: iron and steel must have all manufacturing from initial melting through coating occur in the US; manufactured products must be made in the US with GREATER THAN 55 percent US component cost, so exactly 55.0 percent does not pass; construction materials must have all manufacturing occur in the US. Where an agency phases a standard in, the date the project's federal funds were obligated decides which phase applies. Thresholds and waiver categories are cited to their official source and flagged verified or Unverified. ## API surface Base URL: https://www.sourceory.com/api/v1. Auth: Every endpoint (determine, thresholds, waivers, pricing) is free at the anonymous rate and needs no key to try. Send `Authorization: Bearer src_live_...` (or `x-api-key`) to lift the throttle to your plan's quota. A `src_test_...` key runs the real engine, is throttled, and never bills. No endpoint is paywalled: the recurring paid features (saved history, cross-agency compare, the audit-ready record export) live in the web app and are gated there. OpenAPI: https://www.sourceory.com/api/openapi. MCP: https://www.sourceory.com/api/mcp (tools: determine_baba, get_thresholds, get_waivers). - GET /api/v1: A self-describing index of the whole API surface: every endpoint with its summary and auth requirement, plus links to the OpenAPI document, the MCP server, the docs and machine-readable pricing. Start here if you are discovering this API programmatically. Free, keyless and not rate-limited. - POST /api/v1/determine: Run a Build America, Buy America (BABA) domestic-content determination on a project bill of materials for a funding agency. Deterministic: no model, so identical input always returns an identical verdict. Each line returns one of four verdicts: compliant, non_compliant (fails the standard on the facts supplied), waiver_eligible (fails the standard AND the project-level de minimis test was computed and passed, so a de minimis waiver may cover it; it must still be applied for and granted and is NOT a pass), or insufficient_data (facts supplied cannot reach a verdict, also NOT a pass). A non_compliant line may carry waiverRoutes: qualitative waiver categories whose tests turn on facts this API does not hold, offered as leads to investigate and never as findings. Iron & steel and construction materials use an all-manufacturing-in-US test; manufactured products use the US component-cost test, which is STRICTLY GREATER THAN the threshold, so a product at exactly 55.0% fails. summary.compliantOverall is true only when every line is compliant. Send asOfDate: standards phase in by project obligation date, and the date used is reported back in standardsAsOf. An agency slug we do not hold yields agency:null and insufficient_data lines rather than a guess. Supports an `Idempotency-Key` header for keyed callers: replaying the same key with the same body returns the original result rather than a second billable call, and reusing a key with a different body returns 422 rather than another project's verdict. - GET /api/v1/thresholds: The BABA domestic-content standards. With no query, the full cross-agency matrix (every loaded agency by material category). With ?agency=, that agency's three standards with the threshold, effective date and the OMB or agency citation behind each. An unknown slug returns a not_found error listing the agencies we hold, never a fabricated threshold. - GET /api/v1/waivers: The BABA waiver categories. With no query, all five (public_interest, nonavailability, unreasonable_cost, de_minimis, small_grants), each with its objective test where one exists (de minimis 5% cap, unreasonable cost 25% differential) and its citation. With ?waiver=, that one category. - GET /api/v1/pricing: Machine-readable pricing: every plan id, its monthly price (read live from lib/plans.ts, never hardcoded), what it includes, the included monthly API-call allowance (a hard ceiling, not a meter), rate limits, and whether it grants the determination-record export. Lets an agent self-select a plan without a human reading the pricing page. Free, keyless, not rate-limited. ## Cited BABA domestic-content standards, by funding agency ### OMB Made in America Office (omb) - Office of Management and Budget - Made in America Office Program: Government-wide BABA baseline (OMB M-24-02).

It may be project-specific or issued as a general applicability waiver, and must be construed to maximize use of US-made goods. Applies when: The head of the Federal agency finds that applying the domestic content preference would be inconsistent with the public interest. Source: OMB M-24-02, Section 70914(b) of BABA and 2 CFR 184.7 (https://www.whitehouse.gov/wp-content/uploads/2023/10/M-24-02-Buy-America-Implementation-Guidance-Update.pdf) [verified] ### Nonavailability Waiver (nonavailability) A waiver granted when the required iron, steel, manufactured products, or construction materials are not produced in the United States in sufficient and reasonably available quantities or of a satisfactory quality. Applies when: Domestic products are not produced in sufficient and reasonably available quantities or of a satisfactory quality. Source: OMB M-24-02, Section 70914(b) of BABA and 2 CFR 184.7 (https://www.whitehouse.gov/wp-content/uploads/2023/10/M-24-02-Buy-America-Implementation-Guidance-Update.pdf) [verified] ### Unreasonable Cost Waiver (unreasonable_cost) A waiver granted when including US-produced materials would increase the cost of the overall project by more than 25 percent. Objective test: Domestic preference would increase overall project cost by more than 25 percent Applies when: The inclusion of domestically produced materials will increase the cost of the overall project by more than 25 percent. Source: OMB M-24-02, Section 70914(b) of BABA and 2 CFR 184.7 (https://www.whitehouse.gov/wp-content/uploads/2023/10/M-24-02-Buy-America-Implementation-Guidance-Update.pdf) [verified] ### De Minimis Waiver (de_minimis) A general applicability public interest waiver that agencies may adopt for infrastructure purchases below a de minimis threshold. OMB gives the example of five percent of applicable project costs up to a maximum of $1,000,000, where applicable project costs are the material costs subject to the Buy America preference. Objective test: Cumulative cost of non-domestic components is 5% or less of total material cost Applies when: Non-domestic content cumulatively falls at or below the de minimis threshold (example: 5 percent of applicable project costs, capped at $1,000,000). Source: OMB M-24-02, general applicability public interest waiver examples (https://www.whitehouse.gov/wp-content/uploads/2023/10/M-24-02-Buy-America-Implementation-Guidance-Update.pdf) [verified] ### Small Grants Waiver (small_grants) A public interest waiver agencies may consider for awards at or below the Simplified Acquisition Threshold. OMB notes the SAT is currently $250,000, and the award, inclusive of other funding sources, is not anticipated to exceed the SAT over the life of the award. Objective test: Total Federal award does not exceed the Simplified Acquisition Threshold (currently $250,000) Applies when: The total Federal award is at or below the Simplified Acquisition Threshold and is not expected to exceed it over the life of the award. Source: OMB M-24-02, general applicability public interest waiver examples (https://www.whitehouse.gov/wp-content/uploads/2023/10/M-24-02-Buy-America-Implementation-Guidance-Update.pdf) [verified] ## Honesty semantics verdict values: compliant, non_compliant (fails the standard on the facts supplied), waiver_eligible (fails the standard AND the project-level de minimis test was computed and passed; a waiver must still be granted; NOT a pass), insufficient_data (facts supplied cannot reach a verdict; NOT a pass). waiverRoutes on a non_compliant line are qualitative waiver categories that were NOT evaluated: leads, never findings. The manufactured-product test is strictly greater than the threshold, so exactly 55.0 percent fails. Standards phase in by project obligation date; send asOfDate and read standardsAsOf back. confidence: verify means Unverified, verified means confirmed on the cited page. Sourceory provides Build America, Buy America compliance guidance based on published OMB and agency sources. It is not legal advice and not an official agency determination or waiver. BABA guidance and waivers are updated over time and are fact-specific. Always confirm against the funding agency's current guidance and your grant terms before certifying compliance or applying for a waiver.
