# Days Sales Outstanding – Local Finite-Change Elasticity Calculator

> Days Sales Outstanding – Local Finite-Change Elasticity Calculator is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-22).

Computes the local finite-change elasticity of Days Sales Outstanding (DSO) with respect to a specified input variable, showing how DSO responds to a small percentage change in that input.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability days-sales-outstanding-local-finite-change-elasticity-calculator-303f27b3 -d '<json body>'
```

Example prompt: Calculate the local finite-change elasticity of Days Sales Outstanding with a 1% step change in average_receivables, using a baseline of average receivables $8,000, net credit sales $40,000, and period of 365 days — and give me the formula and any limitations.

## When to prefer this

Choose this endpoint when you need a quick, point-estimate sensitivity measure of how DSO reacts to a marginal change in one specific input variable. It is ideal for single-variable what-if analysis at a specific operating point without running a full sensitivity table. Prefer the one-input sensitivity table sibling endpoint when you need DSO responses across a range of input values rather than a single local approximation.

## Known failure modes

- net_credit_sales of zero causes division by zero — must be excluded per schema exclusiveMinimum
- step_percent outside 0.01–10 range returns validation error
- average_receivables of zero may produce undefined elasticity (division edge case)
- period_days outside 1–3660 range rejected by schema
- missing required baseline fields returns schema validation error
- payment not completed results in 402 response with no computation

## How this service works

Days sales outstanding - Local finite-change elasticity: Measure output response to a supplied small percentage change in one nonzero input; local approximation. Metric: Days sales outstanding. 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 local finite-change elasticity report.

## Output

Returns a JSON object containing the computed local finite-change elasticity coefficient for DSO relative to the chosen input, along with the underlying formula used, measurement units, and a statement of limitations for this local approximation approach.
