##### 2026-10-11

*Changes*

- After a rate limit the actor now waits and slows down instead of switching IP addresses. If the VAT white list or KRS keeps limiting it, the actor stops asking that register for the rest of the run; rows then rely on the other register or come back unverified and free of charge, and the status message says why.

##### 2026-09-30

*Fixes*

- The register that finds the company is part of the company record price. The white list used to be charged again as an extra source, and the KRS extract now counts as one only when it comes on top of the white list.
- Each row carries the white list request identifier of its own search. With more than 30 NIPs, every row used to get the identifier of the last search.
- A company whose white list search failed is marked unverified and not charged. It used to be reported as not registered.
- Ten-digit numbers starting with `000` are read as KRS numbers. About 1 in 11 of them also passes the NIP checksum and used to be read as a NIP and reported as not registered.

*Changes*

- The risk flag for an invoice account missing from the white list says the cost may not be tax-deductible and that you can become jointly liable for the VAT unless you file a ZAW-NR notice within 7 days.

##### 2026-09-28

*Changes*

- `companies` can also be sent as `nip`, `nips`, `krs`, `ids` or other common field names, or as one text with values separated by commas or new lines.

##### 2026-09-27

*Changes*

- The watch field is now called `watchName`. Runs that still send the old name `watchKey` keep working.

##### 2026-09-24

*Changes*

- Lower price per company record on every plan.

##### 2026-09-06

*Fixes*

- Watch mode failed when more than one of our actors used it in the same Apify account. Each actor now keeps its own snapshots.

##### 2026-09-03

*Changes*

- Lower prices on the Free plan: the run fee went from $0.03 to $0.001, a company record from $0.008 to $0.004 and an extra source from $0.003 to $0.001.

##### 2026-09-02

*Features*

- First public version: VAT white list status and published accounts by NIP or KRS number, an invoice account check against the white list, the KRS extract with section 6 entries, a VIES confirmation and a watch mode that reports changes between runs.
