# Company change signals, last 365 days: name, address, legal form, business line, register entries, LEI status — $0.03

`GET /v1/data/company/signals/{country}/{id}`

## Request

- URL: `https://x402.asterpay.io/v1/data/company/signals/{country}/{id}`
- Auth: one of:
  - API key in header `PAYMENT-SIGNATURE`

Dated register events for one company over the last 365 days (or since ?since=YYYY-MM-DD; the response returns next_since for the next poll), newest first, with flags an agent can act on: name_changed_90d, address_changed_90d, legal_form_changed_365d, business_line_changed_365d, situation_recorded_365d, ended, lei_lapsed, lei_renewal_due_90d. country=fi reads PRH register events and the GLEIF LEI record; country=lei reads GLEIF only; country=gb reads Companies House filing history (when enabled). A registered change is a fact; its meaning is the caller's interpretation. Source: PRH (Finnish Trade Register) / GLEIF / Companies House (CC BY 4.0 (PRH); CC0 (GLEIF); OGL (Companies House)). Cadence: daily; observed_at in the response is the upstream timestamp.
