Base URLs

Environment	Base URL
Stage / UAT	`https://uat-ext.signcare.io`
Production	`https://ext.signcare.io`

All Core endpoints are prefixed with /api/v1/.

Authentication

Every endpoint requires these two headers:

X-API-KEY:    <your-api-key>
X-API-APP-ID: <your-app-id>

See the Authentication guide for details.

Rate limits

Core endpoints default to 50 requests / minute per IP + API Key, with lower limits on the heaviest endpoints. See Rate Limits.

Any endpoint that retrieves personal data from a government or financial database requires an explicit consent field:

{
  "consent": "Y",
  "consent_text": "I hear by declare my consent agreement for fetching my information via SignCare API"
}

Your end-user must provide this consent (via your UI) before you make the call.

Response envelope

All Core endpoints return the same JSON envelope:

{
  "success": true,
  "data": { /* endpoint-specific payload */ },
  "request_id": "correlation-id-you-sent-or-we-generated",
  "timestamp": "2026-04-21T10:00:00Z"
}

On error, see Error Codes for the envelope shape.
