Weatherstack Data Extractor

Vern's Weatherstack extractor imports a new user's other data — current weather, forecast, historical, and location lookup — into your product through a single managed migration, handling Weatherstack's auth, pagination, and rate limits for you. It's built for teams onboarding customers off Weatherstack who want their data in your app from day one.

Objects Vern extracts

Vern extracts the full set of queryable Weatherstack objects (4 total), including: Current Weather, Forecast, Historical, and Location Lookup.

Output schema

Normalized JSON per object with referential keys preserved, so the relationships between your user's records survive the import. Timestamps are returned in ISO 8601. Delivered as JSON or CSV, or loaded straight into your own application database or pushed to your API — whatever your product expects.

Where it can land

Your own application database (Postgres, MySQL), a direct push to your API or webhook, or JSON/CSV files, plus another other system (Aviationstack, Bluetally, Breezometer) when a user is switching tools.

Source details

Built for the source type shown above, with extractor content refreshed from the collection record.

Managed by Vern

The details you normally have to build yourself.

Authentication

API key / access token. Your user pastes their Weatherstack API key once when they sign up; Vern stores it encrypted and attaches it to every request, handling header signing and retries so you never touch the raw credential.

Pagination

Vern detects and handles Weatherstack's paging model (cursor, page-number, or offset) internally and returns one consistent, de-duplicated result set — so you import a user's complete data without ever managing page tokens.

Rate limits and gotchas

Weatherstack enforces its own API rate limits. Vern queues and throttles requests internally so importing a new user's data never trips a 429 — even on a large account.

API-key sources rarely surface their true rate ceilings until you hit a 429 mid-import, and many silently cap page size. Vern throttles to stay under the limit and normalizes paging so a partial pull never lands a user in your product with missing data.

API quickstart

1. Create a migration for Weatherstack
curl -X POST https://app.vern.so/api/v1/migrations \
  -H "x-api-key: $VERN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "name": "Weatherstack → Postgres", "source": "Weatherstack" }'
→ { "migration_id": "mig_..." }
2. Generate the extraction recipe (pulls live via the Weatherstack API)
curl -X POST https://app.vern.so/api/v1/migrations/$MIGRATION_ID/runs \
  -H "x-api-key: $VERN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "kind": "generate", "extract_via_api": true }'
3. Run the approved extraction
curl -X POST https://app.vern.so/api/v1/migrations/$MIGRATION_ID/runs \
  -H "x-api-key: $VERN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "kind": "execute" }'
4. Download the normalized CSV export
curl https://app.vern.so/api/v1/migrations/$MIGRATION_ID/exports/{template} \
  -H "x-api-key: $VERN_API_KEY" -o weatherstack_export.csv

A cleaner way to extract without rebuilding source-specific plumbing.

Common questions

Can I keep a user's Weatherstack data in sync after the first import? Vern supports re-running an import on demand; incremental change tracking depends on what Weatherstack's API exposes for each object.

Can I move a user from Weatherstack to Aviationstack? Yes — Vern normalizes the Weatherstack data model into typed tables that map cleanly onto Aviationstack and into your own product.

What does it cost to read the Weatherstack API? Weatherstack's own API access follows Weatherstack's pricing/plan; Vern is billed separately per import. Check Weatherstack's developer docs for their current limits.
