How this service works
Supplied-rate currency conversion - Sequential input-change attribution: Change each input from baseline to final in declared field order, reporting each incremental effect; order dependent. Metric: Supplied-rate currency conversion. Supplied figures only; returns JSON with formula, units and limitations. One of 50 calculators with 20 analysis modes. No live feed, financial advice or trade execution. 0.01 USDC includes one bounded sequential input-change attribution report.
Output
A JSON report containing the waterfall attribution broken down step by step: each input field is changed from its baseline to its final value in declared order, with the incremental effect on the converted target amount calculated at each step. The response also includes the formula used, units, and explicit limitations. No live exchange rates, financial advice, or trade execution is provided.
Example use cases
FX desk period-over-period change breakdown
“My FX desk converted 500,000 units last month at a rate of 1.10, and this month we converted 520,000 units at a rate of 1.08. Run a sequential waterfall attribution in field order — source amount first, then rate — so I can see how much of the change in our converted total is from volume versus the rate movement.”
Treasurer hedging impact analysis
“I need to explain to my CFO why our converted revenue changed: we went from converting 1,000,000 source units at 0.95 to 980,000 units at 0.98. Do a step-by-step waterfall starting with the source amount change, then the rate change, and tell me the incremental effect of each.”
Finance model scenario comparison
“For our model review, compare baseline conversion of 250,000 units at a rate of 1.30 against a new scenario of 275,000 units at 1.28 — attribute the difference sequentially in field order (amount first, then rate) so we can see each driver's contribution.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-finance-fx-conversion-waterfall?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to decompose the change in a currency conversion outcome into its constituent drivers using a waterfall (sequential input-change) method with user-supplied rates — not live market rates. It is ideal for period-over-period FX reporting, CFO-level attribution narratives, and finance model explanations where the order of attribution matters and no live data feed or trade execution is required.
Side effects
- Missing required 'before' or 'after' fields returns a validation error
- target_per_source_rate of 0 or negative is rejected (exclusiveMinimum: 0)
- Values outside ±1,000,000,000,000 range will fail validation
- Malformed JSON body returns a 400-level error
- Payment not fulfilled (x402) results in a 402 Payment Required response
