Clinical Trials Search

Search the complete ClinicalTrials.gov database of clinical studies using natural language queries powered by Valyu's semantic search API.

Why This Skill is Powerful No API Parameter Parsing: Just pass natural language queries directly - no need to construct complex search parameters Semantic Search: Understands the meaning of your query, not just keyword matching Full-Text Access: Returns complete trial information including phases, conditions, interventions, and outcomes Image Links: Includes data visualizations when available Comprehensive Coverage: Access to all ClinicalTrials.gov data Requirements Node.js 18+ (uses built-in fetch) Valyu API key from https://platform.valyu.ai ($10 free credits) CRITICAL: Script Path Resolution

The scripts/search commands in this documentation are relative to this skill's installation directory.

Before running any command, locate the script using:

CLINICAL_TRIALS_SCRIPT=$(find ~/.claude/plugins/cache -name "search" -path "/clinical-trials-search//scripts/*" -type f 2>/dev/null | head -1)

Then use the full path for all commands:

$CLINICAL_TRIALS_SCRIPT "CAR-T cell therapy trials" 15

API Key Setup Flow

When you run a search and receive "setup_required": true, follow this flow:

Ask the user for their API key: "To search ClinicalTrials.gov, I need your Valyu API key. Get one free ($10 credits) at https://platform.valyu.ai"

Once the user provides the key, run:

scripts/search setup

Retry the original search.

When to Use This Skill Finding ongoing and completed clinical trials Identifying trial eligibility criteria Recruiting status and enrollment information Comparing treatment approaches in trials Patient recruitment and enrollment research Outcomes and safety data from trials Output Format { "success": true, "type": "clinical_trials_search", "query": "CAR-T cell therapy trials", "result_count": 10, "results": [ { "title": "Trial Title", "url": "https://clinicaltrials.gov/...", "content": "Trial details, phase, conditions, outcomes...", "source": "clinical-trials", "relevance_score": 0.95, "images": [] } ], "cost": 0.025 }

Processing Results With jq

Get trial titles

scripts/search "query" 10 | jq -r '.results[].title'

Get URLs

scripts/search "query" 10 | jq -r '.results[].url'

Extract full content

scripts/search "query" 10 | jq -r '.results[].content'

Common Use Cases Drug Development

Find drug trials

scripts/search "phase 2 trials for Alzheimer's disease" 50

Treatment Research

Search for treatment studies

scripts/search "checkpoint inhibitor combinations in lung cancer" 20

Medical Device Studies

Find device trials

scripts/search "continuous glucose monitoring device studies" 15

Intervention Analysis

Search for intervention studies

scripts/search "behavioral interventions for obesity" 25

Error Handling

All commands return JSON with success field:

{ "success": false, "error": "Error message" }

Exit codes:

0 - Success 1 - Error (check JSON for details) API Endpoint Base URL: https://api.valyu.ai/v1 Endpoint: /search Authentication: X-API-Key header Architecture scripts/ ├── search # Bash wrapper └── search.mjs # Node.js CLI

Direct API calls using Node.js built-in fetch(), zero external dependencies.

Adding to Your Project

If you're building an AI project and want to integrate Clinical Trials Search directly into your application, use the Valyu SDK:

Python Integration from valyu import Valyu

client = Valyu(api_key="your-api-key")

response = client.search( query="your search query here", included_sources=["valyu/valyu-clinical-trials"], max_results=20 )

for result in response["results"]: print(f"Title: {result['title']}") print(f"URL: {result['url']}") print(f"Content: {result['content'][:500]}...")

TypeScript Integration import { Valyu } from "valyu-js";

const client = new Valyu("your-api-key");

const response = await client.search({ query: "your search query here", includedSources: ["valyu/valyu-clinical-trials"], maxResults: 20 });

response.results.forEach((result) => { console.log(Title: ${result.title}); console.log(URL: ${result.url}); console.log(Content: ${result.content.substring(0, 500)}...); });

See the Valyu docs for full integration examples and SDK reference.
