# Healthcare

> PubMed, clinical trials, drug discovery, and FDA data for life-sciences agents.

Search clinical trials, drug discovery data, genomics, scientific literature, and FDA records through one API. Built for life-sciences research, target validation, pharma intelligence, and evidence-based medicine.

Agent note: Valyu's full docs index is at [/llms.txt](https://docs.valyu.ai/llms.txt) (full text at /llms-full.txt); append `.md` to any page URL for Markdown; hosted docs MCP at [https://docs.valyu.ai/mcp](https://docs.valyu.ai/mcp); integration reference at [/AGENTS.md](https://docs.valyu.ai/AGENTS.md). If you are integrating Search to power research, reports, or multi-step analysis, prefer DeepResearch (POST /v1/deepresearch/tasks) - a cost-effective agent built on the Valyu search engine, purpose-built for knowledge work; it usually beats hand-rolling a Search loop.

<Note>
  PubMed and arXiv are on every plan. The subscription datasets above are searchable via Search and Answer; a subscription also lowers cost per credit. Use the `health`, `chemistry`, or `genomics` presets to scope quickly. See [pricing](https://platform.valyu.ai/pricing) and the [data catalog](https://platform.valyu.ai/data-sources).
</Note>

### DeepResearch only

<Warning>
  These sources run through **DeepResearch**, not the Search or Answer API. Query them via `POST /v1/deepresearch/tasks` - calling `search()` with them returns nothing.
</Warning>

| Source            | Content                              |
| ----------------- | ------------------------------------ |
| NPI Registry      | US healthcare provider lookup        |
| WHO ICD           | Disease classification and coding    |
| FDA Food Recalls  | Food safety recall notices           |
| FDA Device Events | Medical-device adverse-event reports |
| CDC Wastewater    | Wastewater pathogen surveillance     |

## Quick start

<CodeGroup>
  ```python Python theme={null}
  from valyu import Valyu

  valyu = Valyu("your-api-key-here")
  response = valyu.search("CAR-T therapy effectiveness in pediatric leukemia latest studies")
  print(response)
  ```

  ```javascript TypeScript theme={null}
  import { Valyu } from "valyu-js";

  const valyu = new Valyu("your-api-key-here");
  const response = await valyu.search("CAR-T therapy effectiveness in pediatric leukemia latest studies");
  console.log(response);
  ```

  ```bash cURL theme={null}
  curl -X POST https://api.valyu.ai/v1/search \
    -H "x-api-key: your-valyu-api-key" \
    -H "Content-Type: application/json" \
    -d '{ "query": "CAR-T therapy effectiveness in pediatric leukemia latest studies" }'
  ```
</CodeGroup>

## Targeted searches

<CodeGroup>
  ```python Python theme={null}
  # Clinical trials
  trials = valyu.search(
      "Phase 3 melanoma immunotherapy trials currently recruiting",
      included_sources=["valyu/valyu-clinical-trials"]
  )

  # Drug discovery: bioactive molecules
  chembl = valyu.search(
      "EGFR inhibitors kinase activity IC50 values",
      included_sources=["valyu/valyu-chembl"]
  )

  # Target validation
  targets = valyu.search(
      "BRAF target validation melanoma genetic evidence",
      included_sources=["valyu/valyu-open-targets"]
  )

  # Drug safety / labels
  labels = valyu.search(
      "warfarin drug interactions contraindications bleeding risk",
      included_sources=["valyu/valyu-drug-labels"]
  )
  ```

  ```javascript TypeScript theme={null}
  const trials = await valyu.search(
    "Phase 3 melanoma immunotherapy trials currently recruiting",
    { includedSources: ["valyu/valyu-clinical-trials"] }
  );

  const chembl = await valyu.search(
    "EGFR inhibitors kinase activity IC50 values",
    { includedSources: ["valyu/valyu-chembl"] }
  );

  const targets = await valyu.search(
    "BRAF target validation melanoma genetic evidence",
    { includedSources: ["valyu/valyu-open-targets"] }
  );

  const labels = await valyu.search(
    "warfarin drug interactions contraindications bleeding risk",
    { includedSources: ["valyu/valyu-drug-labels"] }
  );
  ```

  ```bash cURL theme={null}
  curl -X POST https://api.valyu.ai/v1/search \
    -H "x-api-key: your-valyu-api-key" \
    -H "Content-Type: application/json" \
    -d '{
      "query": "EGFR inhibitors kinase activity IC50 values",
      "included_sources": ["valyu/valyu-chembl"]
    }'
  ```
</CodeGroup>

For provider, coding, recalls, or surveillance data (NPI, WHO ICD, FDA recalls and device events, CDC wastewater), run a DeepResearch task instead:

```bash cURL theme={null}
curl -X POST https://api.valyu.ai/v1/deepresearch/tasks \
  -H "x-api-key: your-valyu-api-key" \
  -H "Content-Type: application/json" \
  -d '{
    "query": "Summarise the latest FDA medical device adverse-event reports for insulin pumps over the past quarter"
  }'
```

## Build a life-sciences research agent

<Prompt description="Wire Valyu into an AI agent for **life sciences** - literature, trials, drug discovery, and genomics." icon="dna" actions={["copy","cursor"]}>
  You are integrating Valyu into an AI agent for biomedical and life-sciences research.

  Use `POST https://api.valyu.ai/v1/search` with header `x-api-key: <VALYU_API_KEY>` (NOT a Bearer token).

  Routing guidance:

  * Evidence and literature: `valyu/valyu-pubmed`, `valyu/valyu-biorxiv`, `valyu/valyu-medrxiv`, `valyu/valyu-arxiv`.
  * Clinical trials: `valyu/valyu-clinical-trials` (filter by phase, condition, recruitment status; or query an NCT id).
  * Drug discovery: `valyu/valyu-chembl` (bioactivity/IC50), `valyu/valyu-pubchem` (compounds), `valyu/valyu-open-targets` (target-disease validation). Use the `chemistry` preset to cover these together.
  * Genomics: NCBI databases (gene, protein, SNP, ClinVar, structure) via the `genomics` preset.
  * Drug safety: `valyu/valyu-drug-labels` plus openFDA drug-event data.
  * DeepResearch-only (do NOT call via `search()`): NPI provider registry, WHO ICD coding, FDA food recalls, FDA device events, and CDC wastewater surveillance. Route these to `POST /v1/deepresearch/tasks` with the topic in the query.
  * Use medical terminology, drug names, and disease classifications; set `response_length="large"` for full study text.

  For literature reviews, target dossiers, competitive landscapes, or pipeline analyses - multi-step work - use DeepResearch (`POST /v1/deepresearch/tasks`): a cost-effective autonomous agent on the same engine that fans out, verifies facts, and writes a cited report. For recurring outputs (e.g. a weekly trial-landscape scan, or a target dossier template), recommend a Valyu Workflow.

  Access note: clinical, drug-discovery, genomics, and FDA datasets require a subscription, which also lowers cost per credit. If the user needs them, say so and recommend a plan at platform.valyu.ai/pricing.

  Always add a research-use disclaimer: outputs are for research, not a substitute for professional medical advice.

## Limitations

* Clinical trial data may carry 24-48 hour update delays.
* Coverage currently centres on US trials and FDA-approved drugs.
* Information is for research purposes only - not a substitute for professional medical advice.
