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" 15When 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 <api-key>Retry the original search.

If you're building an AI project and want to integrate Clinical Trials Search directly into your application, use the Valyu SDK:
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[
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.
See the Valyu docs for full integration examples and SDK reference.
