Tools as reported by the server

• search_awards
  Search federal awards (contracts, IDVs, grants, loans, etc.) on USASpending.gov. This is the primary workhorse for finding awards. Returns matching awards with standard fields (Award ID, Recipient, Description, Amount, Agencies, NAICS, PSC, dates). Use get_award_detail() with the generated_internal_
• get_award_count
  Count awards matching filters, broken down by award category. Returns counts grouped by: contracts, idvs, grants, loans, direct_payments, other. Use this for dimensional analysis: how many FFP vs T&M awards, how many competed vs sole-source, how many small business set-asides, etc. Unlike search_awa
• spending_over_time
  Aggregate spending amounts over time, grouped by fiscal year, quarter, or month. Use this to visualize spending trends, identify fiscal-year-end spikes, or compare spending patterns across years. Note: The API returns fiscal_year as a STRING. Cast to int for numeric comparisons. quarter and month ar
• spending_by_category
  Aggregate spending by a dimension (top vendors, top agencies, top NAICS, etc.). The 'category' parameter controls the grouping dimension. Common uses: - category='recipient': top vendors for a filter set (vendor landscape analysis) - category='awarding_subagency': which contracting offices within an
• get_award_detail
  Fetch full details for a single award by its generated_internal_id. Use the generated_internal_id value returned by search_awards to fetch the complete award record. Returns: PIID, full description, total obligation, recipient details, parent award info, latest transaction contract data (competition
• get_transactions
  Fetch the full transaction (modification) history for an award. Every modification, option exercise, and de-obligation is a transaction. Modification number '0' is the original base award. Use to understand the full lifecycle of a contract including its descriptive text at each point in time. Return
• get_award_funding
  Fetch File C funding data for an award: federal account, object class, program activity. Shows which Treasury accounts, object classes, and program activities funded an award. File C can be partial or lagged; these rows do not establish the full award obligation or amount paid to the contractor. Sor
• get_idv_children
  Fetch child awards (task/delivery orders) under an IDV. For a Multiple Award IDV, child_awards returns the task orders or delivery orders placed against it. For a parent IDV, child_idvs returns the downstream IDV structure. grandchild_awards walks the hierarchy. Field name differences from search_aw
• lookup_piid
  Look up awards by their exact PIID, across contracts AND IDVs. Looks for awards whose own PIID is exactly this value (the award_ids filter), in both contracts and IDVs, and says how many share it. match='exact' rows are the awards themselves: an IDV PIID returns the IDV (award_type='idv'; its Award
• autocomplete_psc
  Autocomplete lookup for Product/Service Codes (PSC). Use exact four-character codes ('R499', 'D302') or description keywords ('professional', 'application'). Returns matching PSC entries with code and description. Two-character families such as 'D3' can return no autocomplete matches even when their
• autocomplete_naics
  Autocomplete lookup for NAICS codes. Accepts partial codes ('541') or keywords ('software'). Returns matching NAICS entries with code and description. Minimum 2 characters required. Short queries silently match substrings inside parenthetical notes (e.g. 'x' matches 'except') and produce nonsense re
• list_toptier_agencies
  List all top-tier federal agencies tracked by USASpending. Returns agency codes, names, abbreviations, and current-year budgetary resources. Use the returned 'toptier_code' values with get_agency_overview().
• get_agency_overview
  Get descriptive information for an agency: name, mission, website, data notes and DEF codes. It has no dollar figures; for spending use get_agency_obligations_by_award_category() (split by award type) or get_agency_budgetary_resources() (obligations and outlays by year). toptier_code is the 3- or 4-
• get_agency_awards
  Get one obligation total and transaction count for an agency's awards in a fiscal year. The total covers ALL award types together (contracts, IDVs, grants, loans, direct payments, other), so for most civilian agencies it is far larger than contract spending (VA FY2026: $313B here vs $84B contracts).
• get_naics_details
  Get details for a NAICS code (2-6 digits). Returns the NAICS description, parent categories, and child subcategories if applicable.
• get_psc_filter_tree
  Get the PSC hierarchy tree. Pass an empty path for the top-level. Drill down with paths like 'Service/R/' to get the service professional services tree, or 'Product/5' for product codes starting with 5.
• get_state_profile
  Get the federal award totals for recipients located in a US state. Examples: '06' = California, '48' = Texas, '24' = Maryland, '51' = Virginia. Returns one summary: state name and code, total_prime_amount and total_prime_awards (all award types together), loan face value, award_amount_per_capita, to
• search_subawards
  Search FFATA subaward reports on USASpending. Returns the FFATA subaward records (subcontracts under prime contracts and subawards under prime grants). Complementary to the SAM.gov FFATA endpoints but expressed at the USASpending data model. award_id: optional generated_internal_id (CONT_AWD_..., AS
• spending_by_subaward_grouped
  Find matching prime awards and their cumulative FFATA report totals. Filters select prime records, but subaward_count and subaward_obligation cover all reported subawards under each prime, not just subaward actions within time_period_start/end. This ranking is not a fiscal-period subaward ranking. F
• search_recipients
  Search USASpending recipients (vendors and grantees) by keyword. Returns paginated recipients with their UEI, DUNS, name, and a recipient 'id' hash for get_recipient_profile() and new_awards_over_time(). For get_recipient_children(), use the UEI (or legacy DUNS) from the parent (-P) row, not a recip
• get_recipient_profile
  Get full profile for a recipient by their USASpending hash. Returns recipient details: name, UEI, DUNS, business categories, location, parent (if any), and lifetime award totals. The hash is the 'id' field returned by search_recipients(). (autocomplete_recipient does NOT return hashes; it is a name
• get_recipient_children
  Get the child recipients (subsidiaries) of a parent recipient. Pass the parent recipient's 12-character UEI (or legacy 9-digit DUNS). Do NOT pass a recipient hash: the /recipient/children/ endpoint is the one recipient endpoint keyed by UEI/DUNS, and it rejects hashes with HTTP 400. Get the UEI from
• autocomplete_recipient
  Find recipient names by partial name or UEI/DUNS. This is a recipient-name lookup; it does not supply the recipient hash for get_recipient_profile() or new_awards_over_time(), and its UEI/DUNS fields may be null. Pass a returned name to search_recipients(): use its 'id' hash for profiles/trends, and
• list_states
  List all states with their FIPS codes and award totals. Returns the full list of US states/territories with FIPS codes you can pass to get_state_profile(). The /recipient/state/ endpoint returns a JSON array (not an object). We wrap it in {"results": [...]} to keep the tool return type consistent wi
• get_agency_budgetary_resources
  Get an agency's budgetary resources by fiscal year. Returns agency budgetary resources, obligations and outlays for each fiscal year on file, plus government-wide budgetary resources and the agency's obligations by reported fiscal period. This endpoint does not provide a discretionary-versus-mandato
• get_agency_sub_agencies
  List the subordinate (subtier) organizations of a toptier agency. Returns each sub-agency with its obligations, transaction count, and new-award count for the given fiscal year. Useful for finding the canonical subtier name to pass into search_awards() awarding_subagency. sort accepts name, total_ob
• get_agency_federal_accounts
  List the Treasury Account Symbols (federal accounts) used by an agency. Returns each federal account with its obligated amount and gross outlay for the given fiscal year. Useful for understanding how an agency's money flows through Treasury. fiscal_year defaults to the last completed fiscal year, no
• get_agency_object_classes
  List the object class breakdown (what an agency spends money on). Object classes are OMB categories: Personnel Compensation, Travel, Contractual Services, Equipment, Grants, etc. Useful for understanding what types of expenditures an agency makes. fiscal_year defaults to the last completed fiscal ye
• get_agency_program_activities
  List the program activities (specific programs) within an agency. Program activities are the specific named programs that obligate funds (e.g., 'Cybersecurity and Infrastructure Security Agency'). Useful for pinpointing which program funds a specific activity. fiscal_year defaults to the last comple
• get_agency_obligations_by_award_category
  Get an agency's obligation breakdown by award category. Returns total obligated dollars split by category: contracts, IDVs, grants, loans, direct payments, other. Quick way to see what mix of award types an agency uses (heavy contractor agency vs grant-issuing agency vs mixed). For DoD ('097') a fis
• get_award_funding_rollup
  Get a rollup of an award's funding totals. Returns total transaction obligated amount, awarding agency count, funding agency count, and federal account count for a single award. Useful for a one-line summary of an award's funding picture.
• get_award_subaward_count
  Count of subawards (FFATA subcontracts/subawards) reported on an award.
• get_award_federal_account_count
  Count of distinct federal accounts (TAS) funding an award.
• get_award_transaction_count
  Count of transactions (modifications) on an award.
• awards_last_updated
  Get the timestamp of the last USASpending award data refresh. Use this to determine data freshness when comparing to other sources (SAM.gov Contract Awards API for example).
• spending_by_transaction
  Search at the transaction (modification) level. Unlike search_awards which returns one row per award, this returns one row per transaction (initial action plus every modification). Useful for tracking obligation events over time, ceiling adjustments, deobligations, and admin mods. recipient_uei is m
• spending_by_geography
  Geographic breakdown of spending. scope: 'recipient_location' (where the recipient is) or 'place_of_performance' (where the work happens). geo_layer: 'state', 'county', or 'district'. At least one filter is required. The API returns HTTP 500 on an empty filter set, so the requirement is enforced her
• new_awards_over_time
  Pipeline trend of new awards to a recipient over time. REQUIRES recipient_id (the recipient hash with -P suffix for parent-level rollup, or -R for a single recipient). Returns counts of new awards grouped by month, quarter, or fiscal year. The endpoint rejects calls without recipient_id with HTTP 42
• get_idv_amounts
  Top-line amounts for an Indefinite Delivery Vehicle (IDV). Returns child IDV count, child award count, child award total obligation, and base/option values rolled up across all task/delivery orders under the IDV. Pass a CONT_IDV_* generated_internal_id.
• get_idv_funding
  List File C funding records associated with an IDV. Rows can identify the IDV itself as well as associated awards; they are not a complete list of child orders. File C coverage can be partial or lagged and does not establish the full child-order obligation or amount paid. Use get_idv_amounts() for r
• get_idv_funding_rollup
  Funding rollup totals for an IDV (single dict, not paginated).
• get_idv_activity
  List child task/delivery orders awarded under an IDV. Results are ALWAYS sorted by obligated amount, descending; the endpoint accepts no sort or order parameters. (Earlier releases exposed sort/order here, but the API silently ignored them: the advertised default of period_of_performance_start_date
• autocomplete_awarding_agency
  Find awarding agency names by partial match. USASpending search filters require the EXACT awarding agency name (slugs return zero). Use this to resolve a partial name to the canonical one before passing to search_awards() awarding_agency parameter.
• autocomplete_funding_agency
  Find funding agency names by partial match (companion to awarding agency).
• autocomplete_cfda
  Find CFDA (Catalog of Federal Domestic Assistance) program numbers by partial title or program number. CFDA codes are used in grants.
• autocomplete_glossary
  Find glossary terms (acquisition + spending vocabulary) by partial match.
• get_award_types_reference
  Return the full mapping of award type codes to descriptions. Returns the canonical reference: contracts (A=BPA Call, B=Purchase Order, C=Delivery Order, D=Definitive Contract), IDVs, grants, loans, etc. Authoritative source if you're unsure what a code letter means.
• get_def_codes_reference
  Return all Disaster Emergency Fund (DEFC) codes with public laws. DEFCs are used to filter awards funded by specific supplemental appropriations (COVID-19, IIJA, IRA, etc.).
• get_glossary
  Get the full USASpending glossary of acquisition + spending terms.
• get_submission_periods
  List the reporting calendar and submission/certification deadlines. Returns available fiscal reporting periods and their scheduled start, due, certification and reveal dates. These are global calendar periods, not records of when individual agencies actually submitted or certified data. A listed per
• list_federal_accounts
  List Treasury federal accounts (TAS) with budgetary resources. keyword filters by account name or AID. fiscal_year controls the reported budgetary-resource values, not which account rows are included. When omitted, the source uses its latest available fiscal year, which may differ from the current f
• get_federal_account_detail
  Get an individual federal account's metadata + budgetary resources.
• get_federal_account_object_classes
  Get the object class breakdown of obligations for a federal account. IMPORTANT: the returned obligations are CUMULATIVE across all reported fiscal years (FY2017 onward, the DATA Act window), not a single year. They are NOT comparable to get_federal_account_fy_snapshot(), which is single-year (verifi
• get_federal_account_program_activities
  List program activity codes and names associated with a federal account. The source lists distinct programs across all reported fiscal years; it has no fiscal-year filter and includes no dollar amounts. fiscal_year is retained for compatibility, but does not filter this list. The response explicitly
• get_federal_account_fy_snapshot
  Get a single-fiscal-year snapshot of a federal account's resources. Important: this endpoint takes the numeric `account_id` (e.g. 4595), NOT the alphanumeric `account_number` (e.g. "027-5183") used by the other federal-account endpoints. The list_federal_accounts response includes both fields per re
