Why filter by San Francisco

San Francisco principals concentrate startups, funds, and professional services. City match keeps Bay Area noise out of your queue when you only underwrite or prospect inside the city — not every California filing statewide.

What we cover

  • Entity status changes — Active, Suspended, Forfeited, Dissolved
  • Franchise Tax Board standing and Secretary of State standing fields
  • Registered agent standing and suspension dates
  • New formations (`INSERT`) and standing updates (`UPDATE`)

San Francisco match example

Match on California and San Francisco so only this principal city reaches your webhook:

client.register(
    match={"state": "CA", "principal_city": "San Francisco"},
    actions=["INSERT", "UPDATE"],
    callback_url=callback_url,
)

Example webhook

  "after": {
    "status": "Suspended",
    "standing_ftb": "Not Good",
