# Clinical Trial Status Lookup

> Clinical Trial Status Lookup is a paid API for AI agents from oracles-production.up.railway.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Retrieves stored detail for a single clinical trial study by its entityId (e.g. 'nct:NCT06369220'), or lists all tracked clinical trial entities.

## Facts

- Endpoint: GET https://oracles-production.up.railway.app/v1/clinical-trials/status
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15

- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_SK7f-OS4SNY2mp_2VPpB6

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability clinical-trial-status-lookup-a2ce265b
```

Example prompt: Can you pull up the stored details for clinical trial NCT06369220? I want to check its current status and trial info.

## When to prefer this

Use this endpoint when you need structured, stored details about a specific clinical trial identified by its NCT number or entity ID, especially within an automated pipeline that requires machine-readable trial metadata. Prefer this over live ClinicalTrials.gov scraping when cached/stored data is sufficient and cost-efficiency matters.

## Known failure modes

- Missing or invalid entityId format returns empty or error response
- Unknown entityId (trial not tracked) returns empty entity or 404
- Malformed query parameters result in 400 error
- Payment required (402) if x402 payment header is not included
- Network timeout from upstream Railway deployment

## How this service works

Stored detail for a single study (entityId like 'nct:NCT06369220').

## Output

Returns a JSON object containing stored entity details for the specified clinical trial, including study metadata, status, phase, and other tracked fields. If no ID is provided, returns a list of all tracked clinical trial entities.
