## Methods

### Search grants

Operation `search_grants`, version 1. 1 credit per call.

Find NIH research grants by topic, organisation, or researcher name. Searches the last five fiscal years by default; grants without a published abstract or award amount show null.

**Input**

| Field | Type | Required | Example | Description |
|---|---|---|---|---|
| `sort` | string | no | `"largest_amount"` | Newest awards by notice date, or largest award amounts. |
| `query` | string | yes | `"Johns Hopkins University"` | Topic, organisation, or researcher name, such as Alzheimer's or Johns Hopkins University. |
| `state` | string | no | `"MD"` | Organisation state name or two-letter code, such as Maryland or MD. |
| `max_results` | integer | no | `3` | Maximum number of grants to return, such as 20. |
| `fiscal_years` | string | no | `"2024-2026"` | Fiscal year or inclusive year range, such as 2024-2026; defaults to the last five fiscal years. |

## Quick start

Call the API with a Fous API key (`FOUS_API_KEY`). To create one, turn on Developer mode in Fous Studio, then open Keys & connections → API keys (https://app.fous.com/keys).

```bash
# First set your key: export FOUS_API_KEY='YOUR_FOUS_API_KEY'
: "${FOUS_API_KEY:?Set FOUS_API_KEY before running this example}"

curl 'https://api.fous.com/v1/query' \
  --fail-with-body --silent --show-error --max-time 120 \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H 'Content-Type: application/json' \
  --data-raw '{
  "api": "@nih-reporter",
  "visibility": "public",
  "operation": "search_grants",
  "version": 1,
  "input": {
    "sort": "largest_amount",
    "query": "Johns Hopkins University",
    "state": "MD",
    "max_results": 3,
    "fiscal_years": "2024-2026"
  },
  "response": {
    "format": "json"
  }
}'
```

```python
# Save as fous.py and run with python3 fous.py. No packages needed.
# First set your key: export FOUS_API_KEY='YOUR_FOUS_API_KEY'
import json
import os
import urllib.error
import urllib.request

api_key = os.environ.get("FOUS_API_KEY")
if not api_key:
    raise RuntimeError("Set FOUS_API_KEY before running this example")

body = json.loads("{\n  \"api\": \"@nih-reporter\",\n  \"visibility\": \"public\",\n  \"operation\": \"search_grants\",\n  \"version\": 1,\n  \"input\": {\n    \"sort\": \"largest_amount\",\n    \"query\": \"Johns Hopkins University\",\n    \"state\": \"MD\",\n    \"max_results\": 3,\n    \"fiscal_years\": \"2024-2026\"\n  },\n  \"response\": {\n    \"format\": \"json\"\n  }\n}")
request = urllib.request.Request(
    "https://api.fous.com/v1/query",
    data=json.dumps(body).encode("utf-8"),
    headers={
        "Authorization": f"Bearer {api_key}",
        "Content-Type": "application/json",
    },
    method="POST",
)
try:
    with urllib.request.urlopen(request, timeout=120) as response:
        result = json.load(response)
except urllib.error.HTTPError as error:
    raise RuntimeError(f"HTTP {error.code}: {error.read().decode('utf-8', errors='replace')}") from error
if result.get("success") is False:
    raise RuntimeError(result.get("error", {}).get("message", "Request failed"))
print(json.dumps(result["data"]["output"], indent=2))
```

```typescript
// Save as fous.mts and run with npx tsx fous.mts.
// First set your key: export FOUS_API_KEY='YOUR_FOUS_API_KEY'
const apiKey = process.env.FOUS_API_KEY;
if (!apiKey) throw new Error("Set FOUS_API_KEY before running this example");

const response = await fetch("https://api.fous.com/v1/query", {
  method: "POST",
  headers: {
    "Authorization": `Bearer ${apiKey}`,
    "Content-Type": "application/json",
  },
  signal: AbortSignal.timeout(120_000),
  body: JSON.stringify({
  "api": "@nih-reporter",
  "visibility": "public",
  "operation": "search_grants",
  "version": 1,
  "input": {
    "sort": "largest_amount",
    "query": "Johns Hopkins University",
    "state": "MD",
    "max_results": 3,
    "fiscal_years": "2024-2026"
  },
  "response": {
    "format": "json"
  }
}),
});
type ApiResult = { success: boolean; data?: { output: unknown }; error?: { message: string } };
const result: ApiResult = await response.json();
if (!response.ok || result.success === false) {
  throw new Error(result.error?.message ?? `HTTP ${response.status}`);
}
if (!result.data) throw new Error("Missing API response data");
console.log(result.data.output);
```

Or describe the data in plain language: send `{"api":"@nih-reporter","prompt":"Describe the data you need, with every detail"}` to the same URL. Fous fills in the input, runs the method that fits and returns only the fields you asked for; `data.route.calls[].request` is the exact call it made. Routing is free; the run costs the same.

## FAQ

### Is Fous affiliated with NIH RePORTER?

No. Fous is not affiliated with NIH RePORTER. This workflow reads the public reporter.nih.gov website and returns its data.

### How much does it cost?

Each run costs 1 credit. With pay-as-you-go, a credit costs 1¢; monthly plans cost less per credit.

### Do I need a NIH RePORTER account?

No. You only need a Fous account.

### How current is the data?

Fous gets the data from reporter.nih.gov when you run it; repeating the same request within a day may return the saved result. Fous checks this workflow automatically; it last passed a check on Sep 29, 2026.
