Alpaca Broker API Data Extractor

Vern's Alpaca Broker API extractor imports a new user's banking & finance data — accounts, account documents, accounts activities, and assets — into your product through a single managed migration, handling Alpaca Broker API's auth, pagination, and rate limits for you. It's built for teams onboarding customers off Alpaca Broker API who want their data in your app from day one.

Know exactly what Vern pulls before you migrate.

Objects Vern extracts

Vern extracts the full set of queryable Alpaca Broker API objects (7 total), including: Account Documents, Accounts, Accounts Activities, Assets, Calendar, Clock, and Country Info. 4 of these support incremental change tracking, so syncs pull only what changed.

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 banking & finance system (Alpha Vantage, Brex, Coin API) 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

Basic authentication (username + password / secret). Your user connects their Alpaca Broker API account once; Vern stores the credential encrypted and signs each request. See Alpaca Broker API's authentication guide.

Pagination

Vern detects and handles Alpaca Broker API'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

Alpaca Broker API enforces its own API rate limits (see Alpaca Broker API's rate-limit docs). Vern queues and throttles requests internally so importing a new user's data never trips a 429 — even on a large account.

Basic-auth sources transmit credentials on every call and often lack granular scopes, so have your user connect a read-only account where possible. Vern stores the credential encrypted and never logs it.

API quickstart

1. Create a migration for Alpaca Broker API
curl -X POST https://app.vern.so/api/v1/migrations \
  -H "x-api-key: $VERN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "name": "Alpaca Broker API → Postgres", "source": "Alpaca Broker API" }'
→ { "migration_id": "mig_..." }
2. Generate the extraction recipe (pulls live via the Alpaca Broker API API)
curl -X POST https://app.vern.so/api/v1/migrations/$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 alpaca-broker-api_export.csv

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

Common questions

Can I keep a user's Alpaca Broker API data in sync after the first import? Yes — 4 Alpaca Broker API objects support incremental change tracking, so after the first full import Vern pulls only what changed on re-run.

Can I move a user from Alpaca Broker API to Alpha Vantage? Yes — Vern normalizes the Alpaca Broker API data model into typed tables that map cleanly onto Alpha Vantage and into your own product.

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