How this service works
Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.
Output
Returns a JSON object with three fields: net (pre-tax amount), tax (VAT portion), and gross (the original total), along with a notice clarifying this is a pure arithmetic calculation and not tax advice.
Example use cases
Invoice line item VAT breakdown
“I received an invoice for £240 including 20% VAT — what is the net amount and how much of that is tax?”
E-commerce price display
“Our product sells for $599 gross and we're in a 15% VAT jurisdiction — what net price and tax amount should we show customers?”
Expense report VAT extraction
“I need to split a €845.50 expense receipt into its net and VAT components — the applicable rate is 19%.”
Technical details
Endpoint
POSThttps://x402-agent.kariguetoazul.workers.dev/api/finance/vat-extract?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, deterministic arithmetic decomposition of a VAT-inclusive gross amount into net and tax components using a rate you already know. It is not a tax rate lookup service and does not validate or recommend rates — use it when the rate is already determined and you need the math done reliably at $0.001 per call.
Side effects
- Missing gross or rate_percent inputs returns a validation error
- Negative values rejected by schema minimum of 0
- Floating-point rounding may produce minor precision differences vs accounting systems
- Extremely large values near the 1,000,000,000,000 maximum may hit edge cases
- Non-numeric inputs cause schema validation failure
