**Short answer.** `https://api.usaspending.gov/api/v2/` exposes federal awards and account balances; most endpoints are POST with a JSON `filters` object. No key.

## Example

```
POST https://api.usaspending.gov/api/v2/search/spending_by_award/
{"filters":{"time_period":[{"start_date":"2023-10-01","end_date":"2024-09-30"}],"award_type_codes":["A","B","C","D"],"place_of_performance_locations":[{"country":"USA","state":"TX","county":"141"}]},
 "fields":["Award ID","Recipient Name","Award Amount","Awarding Agency"],"limit":50,"page":1}
```

## Details

- Fiscal years run 1 October to 30 September; FY2024 is 2023-10-01 to 2024-09-30.
- `/api/v2/references/toptier_agencies/` lists agencies; `/api/v2/agency/{code}/` gives budgetary resources.
- Award type codes: A to D contracts, 02 to 05 grants, 06 to 11 loans and other assistance.
- Download endpoints (`/api/v2/download/awards/`) queue a file for large pulls.

## Pitfalls

- Amounts are obligations, not outlays, unless the endpoint says otherwise.
- County codes are three-digit FIPS inside the state.
