How this service works
Margin of safety - Adjacent period changes: Report adjacent-observation differences and eligible percent changes; no interpolation. Metric: Margin of safety. 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 adjacent period changes report.
Output
A JSON object containing adjacent-observation differences and eligible percent changes for the margin of safety metric across all supplied row pairs, along with the formula used, units, and a limitations note. No data is interpolated — only supplied figures are used.
Example use cases
Quarterly margin of safety drift review
“I've got six quarters of sales figures — actual sales were 50000, 52000, 48000, 55000, 53000, 57000 and break-even sales were 35000, 36400, 33600, 38500, 37100, 39900 — can you calculate the margin of safety change between each adjacent quarter and give me the percent changes too?”
Annual break-even vs actual sales comparison
“For our last five annual periods, actual sales were 200000, 210000, 195000, 220000, 230000 and break-even sales were 150000, 157500, 146250, 165000, 172500 — run the adjacent period margin of safety differences analysis and tell me the formula and units used.”
Monthly operational cost safety buffer tracking
“I have 12 months of data where actual sales range from 8000 to 13000 and break-even sales range from 6000 to 9100 — can you compare month-to-month margin of safety changes using only the supplied figures, no interpolation?”
Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-finance-margin-safety-period-changes?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have your own historical actual_sales and break_even_sales figures and need a period-by-period margin of safety difference report without any smoothing or interpolation. It is ideal for auditable, supply-only financial analysis where you want the raw adjacent changes and percent shifts alongside the formula and unit metadata. Prefer it over interpolation-based or trend-fit endpoints when data integrity and strict use of supplied values are required.
Side effects
- Fewer than 2 rows provided — minimum 2 rows required for any adjacent comparison
- actual_sales value of 0 or missing — field is required and must be a positive non-zero number
- break_even_sales exceeds actual_sales by a large margin, which may yield negative or boundary-case margin of safety values
- More than 200 rows submitted — maximum array size is 200
- Non-numeric values in sales fields cause schema validation failure
- Payment failure or insufficient USDC balance prevents endpoint execution
