Company change signals in a Clay column

Set up once

1. Sign up with your work email; the key (ak_live_...) is shown once.
2. In Clay, store it as a secret named ARCADIUM_API_KEY (never in a table column).
3. Add an enrichment → HTTP API, paste the method, URL and headers of a column below, turn on continue on error and set concurrency to about 5.
4. Map the outputs with the JSON paths in each table, then add the filter.

Errors share one shape, { "error": "<code>", "message": "..." }: 404 not_found (no data, do not retry), 429 (wait Retry-After seconds), 401 (missing or wrong key).
