Clinical trial search

Clinical studies registered on ClinicalTrials.gov by condition, intervention, title, outcome, sponsor, location or any text, with filters for overall status, phase, study type, sex, age group, funder type, posted results, healthy volunteers, start, completion, first-posted and last-update date ranges, distance from a point and NCT ids, and sort. Each study has NCT id, titles, status, type, phases, enrollment, conditions, keywords, interventions, sponsor and collaborators, key dates, results flag, location count and countries, brief summary and link. Pass next_cursor back as cursor; null on the last page.

Every response includes credits_used: the credits this call cost.

Parameters

Every endpoint also takes fresh, raw, fields (see lean responses and caching).

Example

curl "https://api.api.sh/clinicaltrials/v1/search?condition=lung+cancer" \
  -H "x-api-key: $APISH_KEY"

import os, requests

res = requests.get(
    "https://api.api.sh/clinicaltrials/v1/search",
    params={"condition": "lung cancer"},
    headers={"x-api-key": os.environ["APISH_KEY"]},
    timeout=120,
)
res.raise_for_status()
data = res.json()

const url = new URL("https://api.api.sh/clinicaltrials/v1/search");
url.searchParams.set("condition", "lung cancer");

const res = await fetch(url, { headers: { "x-api-key": process.env.APISH_KEY } });
if (!res.ok) throw new Error(`${res.status} ${await res.text()}`);
const data = await res.json();

Response

A JSON object with the fields described above, plus raw (the source's own data), cached, fetched_at and credits_used. Errors return {"success": false, "error": "…"} with the HTTP status (see errors). A lookup that ran but found nothing (404) costs the price above; refused calls and errors on our side are free (what's charged).
