API access

Read estimates, indicators and issued history from the current development release.

1. Choose your data

GET /api/development/v1/nowcasts

GDP and inflation estimates, uncertainty and changes.

GET /api/development/v1/indicators

Official observations and source metadata.

GET /api/development/v1/history

Actual issued estimates and their information dates.

Use region=FI or region=EA. Responses support limit (up to 500) and cursor pagination.

2. Make a request

curl "https://aeis-sand.vercel.app/api/development/v1/nowcasts?region=EA" \
  -H "Authorization: Bearer YOUR_API_KEY"

Use your provisioned key as a Bearer token or in the x-api-key header. Keys stay in your own environment.

Existing institutional endpoints and keys remain compatible. This dedicated development endpoint identifies its release and environment explicitly.

3. Read the response

{
  "data": [...],
  "meta": {
    "source": "aeis-development",
    "as_of": "<snapshot capture time>",
    "vintage": "<registered run ID>",
    "environment": "development",
    "next_cursor": null
  },
  "errors": []
}

Missing values remain null. A release that fails integrity checks is unavailable, rather than replaced with sample data. Authentication failures return 401; unavailable configuration or data returns 503; the existing per-instance rate limiter returns 429 when exceeded.
