  Query, search, and download data from the openFDA API for drugs, devices,
  foods, tobacco, cosmetics, animal and veterinary products, substances, and
  transparency data. Use for FDA adverse events, recalls, labeling, approvals,

# openFDA Search and Query

## Prerequisites

1.  **`uv`**: Read the `uv` skill and follow its Setup instructions to ensure
    `uv` is installed and on PATH.
2.  **User Notification**: If .licenses/openfda_database_LICENSE.txt does not
    already exist in the workspace root directory then (1) prominently notify
    the user to check the terms at https://open.fda.gov/apis/ and
    https://open.fda.gov/license, then (2) create the file recording the
    notification text and timestamp.
3.  **`.env` file**: Make sure the `.env` file exists in your home directory.
    Create one if it does not exist.
4.  **`FDA_API_KEY`** (optional but recommended): Raises the daily request limit
    from 1,000 to 120,000. The skill works without it, but an agent can easily
    exhaust the keyless limit in a single session. You can register for a free
    key at https://open.fda.gov/apis/authentication/. You **MUST** use the safe
    credentials protocol in the `credentials` skill to check for and request
    this key if this skill looks relevant to the user's request.

## Core Rules

-   **Use the Wrapper**: ALWAYS execute the provided helper scripts to query the
    database rather than accessing the database directly. The scripts
    automatically enforce the required rate limit gracefully.

-   **Rate Limiting**: Respect openFDA rate limits. Without API key: 240
    requests/min, 1,000 requests/day per IP. With API key: 240 requests/min,
    120,000 requests/day per key. Always set an API key before running
    multi-query workflows.

> **Warning**: An automated agent can easily exhaust the 1,000-request daily
> limit in a single research session. Always set an API key before running
> multi-query workflows.

> You **MUST** use the safe credentials protocol in the `credentials` skill to
> help the user add `FDA_API_KEY` to their `.env` file if this skill looks
> relevant to the user's request. The script will emit a warning to stderr if no
> API key is detected.

-   **Always Use `--output`**: All subcommands require `--output <file>` to
    write results to a file. This prevents large output becoming overwhelming.
    Use jq or code to read the output file.

-   **Notification**: If this skill is used, ensure this is mentioned in the
    output.

## Utility Script

**Single script for all operations:**

```bash
uv run scripts/openfda_query.py {search,count,download} --output <file> [options]
```

### 1. Search

Search any of the 28 endpoints and save JSON results to a file.

```bash
uv run scripts/openfda_query.py search \
  --category drug --endpoint event \
  --search "patient.drug.medicinalproduct:aspirin" \
  --limit 5 --output /tmp/fda_results.json
```

Stdout prints a compact summary:

```json
{"status": "success", "output": "/tmp/fda_results.json", "results_in_file": 5, "total_matching": 601477}
```

*Options:*

-   `--output`: Output file for full JSON results (required).
-   `--category`: API category — `drug`, `device`, `food`, `tobacco`, `other`,
    `animalandveterinary`, `cosmetic`, `transparency`.
-   `--endpoint`: Endpoint within the category (e.g., `event`, `label`, `510k`).
    See [references/api_endpoints.md](references/api_endpoints.md) for full
    list.
-   `--search`: Query string (e.g.,
    `patient.drug.medicinalproduct:aspirin+AND+serious:1`).
-   `--sort`: Sort field and order (e.g., `receivedate:desc`).
-   `--limit`: Max results (default 10, max 1000).
-   `--skip`: Pagination offset (default 0).
-   `--api_key`: API key (also reads `FDA_API_KEY` env var).

### 2. Count

Count unique values of a field within matching res
