Healthcare Data API for AI - PubMed, Clinical Trials, ChEMBL

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.

What you can do

Clinical research

Trials, protocols, enrolment, and outcomes from ClinicalTrials.gov.

Drug discovery

Bioactivity, compounds, and target validation from ChEMBL, PubChem, Open Targets.

Genomics

NCBI gene, protein, variant, and structure databases.

Pharma intelligence

Pipeline, filings, and competitive landscape via SEC and earnings data.

Sources

Search and Answer API

Source	Content	Access
`valyu/valyu-pubmed`	Biomedical literature	All plans
`valyu/valyu-arxiv`, `valyu/valyu-biorxiv`, `valyu/valyu-medrxiv`	Preprints	arXiv: all plans; others: subscription
`valyu/valyu-clinical-trials`	ClinicalTrials.gov	Subscription
`valyu/valyu-drug-labels` / DailyMed	FDA drug labels	Subscription
openFDA drug events	FDA adverse-event reports	Subscription
`valyu/valyu-chembl`	Bioactive molecules, assays, IC50/binding data	Subscription
`valyu/valyu-pubchem`	Chemical compounds, structures, bioassays	Subscription
`valyu/valyu-open-targets`	Target-disease associations, genetic evidence	Subscription
NCBI genomics (19 DBs)	gene, protein, SNP, ClinVar, structure, taxonomy	Subscription
WHO health data	Global health statistics	Subscription

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 and the data catalog.

DeepResearch only

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

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

from valyu import Valyu

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

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);

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" }'

Targeted searches

# 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"]
)

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"] }
);

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"]
  }'

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

cURL

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"
  }'

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.
