Get started in three steps

Validate your first document using the ZeroDrift Validation API.

​
Step 1: Get your API key

Contact the ZeroDrift team to obtain your API key. Once you have it, you’ll use it in the x-api-key header for all API requests.
x-api-key: YOUR_API_KEY

​
Step 2: Submit content for validation

The quickest way to test the API is with a text snippet:
curl -X POST "https://{api-url}/api/validate_snippet_stream/" \
  -H "x-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "text_snippet": "Our fund guarantees 20% returns with zero risk!",
    "document_category": "retail_investor_letter"
  }'
You’ll receive a job_id in the response:
{
  "job_id": "abc123def456",
  "status": "accepted"
}
For document validation, encode your file as base64:
# Encode your document
DOC_BASE64=$(base64 -i document.pdf)

# Submit for validation
curl -X POST "https://{api-url}/api/validate_stream/" \
  -H "x-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d "{
    \"document_bytes\": \"$DOC_BASE64\",
    \"document_category\": \"retail_investor_letter\"
  }"
For files larger than 6MB, use the presigned URL workflow.

​
Step 3: Get validation results

Use the job_id to retrieve your validation results:
curl -X POST "https://{api-url}/api/validate_stream_result/" \
  -H "x-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"job_id": "abc123def456"}'
Poll until status is done or failed. A completed response includes:
{
  "job_id": "abc123def456",
  "status": "done",
  "overall_status": "issues_found",
  "summary": {
    "total_checks": 25,
    "passed": 20,
    "failed": 3,
    "warnings": 2
  },
  "fixes": [
    {
      "id": "perf_claim_no_disclosure",
      "severity": "high",
      "title": "Performance claim without required disclosure",
      "recommendation": "Add standardized performance disclosure."
    }
  ]
}
