### Tool changes

- 2026-11-12 `rent_ceilings_for_unit` changed (description)
  - before: Every rent ceiling for one unit: HUD FMR (free), plus tax-credit rent limits and the local agency payment standard where your plan includes them. Uses up to 2 calls of your plan. Paid parts are available on: PRO ($29/month, 5,000 calls), ULTRA ($99/month, 50,000 calls), MEGA ($299/month, 250,000 calls). Needs your own Glazed Data API key in the x-api-key header (create one at https://glazeddata.com/rent-limits/pricing/).
  - after: Every rent ceiling for one unit in one answer: HUD Fair Market Rent, which is free and needs no key; the tax-credit (LIHTC) rent limit, on PRO and up; and the local housing agency's voucher payment standard, on ULTRA and up. Each paid part counts as 1 call of your plan, so this tool uses 1 call on PRO and 2 on ULTRA or MEGA. Parts your plan doesn't include are skipped and not charged. Paid parts are available on: PRO ($29/month, 5,000 calls), ULTRA ($99/month, 50,000 calls), MEGA ($299/month, 250,000 calls). The paid parts need your own Glazed Data API key in the x-api-key header (create one at https://glazeddata.com/rent-limits/pricing/).
