How this service works
Local-first data and agent workflow tools from Decision Data Studio, plus verified EU tender shortlists and machine-callable utilities.
Output
Returns a JSON object containing a list of matched trial records (up to 20), each with trial ID, title, phases, conditions, interventions, overall status, start and completion dates, enrollment count and type, primary and secondary endpoints, and a source URL to the ClinicalTrials.gov record. Also includes aggregate metadata: total trials in dataset, number matched, number returned, applied filters, dataset version, and a timestamp. A caveat note reminds that results are public registry data only and not medical advice.
Example use cases
Drug efficacy research for a condition
“Find me up to 15 completed clinical trials on ClinicalTrials.gov studying pembrolizumab as an intervention for non-small-cell lung cancer, with results posted after 2021-01-01 — I want the trial IDs, phases, enrollment counts, and primary endpoints.”
Patient advocacy trial awareness
“Can you look up active and recruiting clinical trials for Duchenne muscular dystrophy, any phase, and give me the titles, start dates, and links so I can share them with a patient support group?”
Competitive landscape scan for biotech
“Search for all phase 2 and phase 3 trials studying CRISPR gene editing interventions with results already posted — give me up to 20, including completion dates and enrollment numbers.”
Technical details
Endpoint
POSThttps://api.ikoles.dev/v1/clinical-trials-queryWhen to prefer
Choose this endpoint when you need structured, machine-readable access to ClinicalTrials.gov data filtered by condition, intervention, phase, or status without scraping the web UI. It is ideal for agents doing biomedical research, competitive intelligence, patient advocacy lookups, or evidence synthesis pipelines where you need trial IDs, endpoints, and enrollment data in a single call. Prefer this over general web search when you need reliable, structured fields like enrollment counts, primary endpoints, and result post dates.
Side effects
- No trials match the specified filters — returns empty trials array with zero matchedTrials
- Query or condition string exceeds 200-character limit — validation error
- Phase or overallStatus value not recognized by the registry — may return zero results
- Limit out of range (below 1 or above 20) — validation error
- Date format incorrect (not ISO 8601 YYYY-MM-DD) — schema validation failure
- Upstream ClinicalTrials.gov data unavailable — service may return error or stale dataset version
