### Tool changes

- 2026-10-05 `usd_ngn_convert` changed (title, description, inputSchema)
  - before: Convert between US dollars and Nigerian naira at the Central Bank of Nigeria's official NFEM rate — the volume-weighted average CBN publishes, not a parallel-market figure. Returns the converted amount with the rate, the trading date it applies to, and the CBN source. Interactive version: https://zaleso.com/ng/fx
  - after: Convert between Nigerian naira and US dollars, pounds, euros and other currencies at the Central Bank of Nigeria's official rate — the latest, or the rate that applied on a past date. The dollar uses the NFEM rate (the volume-weighted average CBN publishes); other currencies use CBN's selling rate. Never a parallel-market figure. Returns the converted amount with the rate, the trading date it applies to, and the CBN source. Interactive version: https://zaleso.com/ng/fx

## Tools (10)

- `amount_in_words`: Spell a monetary amount in words, the way a cheque or an invoice requires — "Four Thousand and Fifty Naira and Seventy-Five Kobo Only". Supports NGN, USD, EUR and GBP with the correct major and minor unit names. It is the row that goes above the signature line on the invoices at https://zaleso.com/invoice
- `base64_convert`: Encode text to Base64, or decode Base64 back to text. UTF-8 throughout, so accented text, emoji, Arabic, Devanagari and CJK survive the round trip — the naive btoa/atob version does not. Interactive version: https://zaleso.com/base64
- `invoice_totals`: Compute invoice totals from line items: per-line totals, subtotal, an optional discount, optional tax (the verified Nigeria VAT preset or any rate you name), a deposit already paid, and the balance due. Country-agnostic. The interactive version also produces the PDF: https://zaleso.com/invoice
- `json_format`: Format (pretty-print) or minify JSON. Invalid input returns the line and column of the error. Interactive version: https://zaleso.com/json
- `ng_gross_for_take_home`: Work backwards from a target take-home to the gross salary that produces it, under the Nigeria Tax Act 2025 (2026 tax year). This is the question employers and contractors actually ask — "what must I pay for them to clear ₦500,000 a month" — and it cannot be answered by applying a rate, because PAYE is banded. Returns the required gross with the full band-by-band working and the statutory source. Informational only — verify with the tax authority. Interactive version: https://zaleso.com/ng/net-salary
- `ng_paye_calculate`: Calculate Nigeria PAYE income tax and net (take-home) salary under the Nigeria Tax Act 2025, effective for the 2026 tax year. Returns monthly take-home, monthly PAYE, the effective rate, and the full band-by-band working, with the statutory source and verification date. Handles pension (8%), NHF (2.5%, voluntary), rent relief (20% of rent, capped at ₦500,000), and the minimum-wage exemption. Figures are informational — verify with the tax authority. Interactive version: https://zaleso.com/ng/paye
- `ng_vat_calculate`: Add Nigerian VAT to a net amount, or extract the VAT already contained in a VAT-inclusive amount. Uses the verified statutory rate from the data layer and returns it with its source and effective date — never an assumed rate. Informational only — verify with the tax authority. Interactive version: https://zaleso.com/invoice
- `password_generate`: Generate a cryptographically secure random password (crypto.getRandomValues with rejection sampling — no modulo bias). Returns the password and its entropy. Interactive version: https://zaleso.com/password
- `qr_generate`: Generate a QR code as an SVG image from text or a URL. The code encodes the value directly — no tracking redirect, so it works forever. Interactive version: https://zaleso.com/qr
- `usd_ngn_convert`: Convert between Nigerian naira and US dollars, pounds, euros and other currencies at the Central Bank of Nigeria's official rate — the latest, or the rate that applied on a past date. The dollar uses the NFEM rate (the volume-weighted average CBN publishes); other currencies use CBN's selling rate. Never a parallel-market figure. Returns the converted amount with the rate, the trading date it applies to, and the CBN source. Interactive version: https://zaleso.com/ng/fx
