## 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 kihustle-json-linear-interpolation-cf28b99b -d '<json body>'
```

Example prompt: I have a numeric array with some missing values — [1, null, 3, null, null, 6] — can you fill in the gaps using linear interpolation?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call linear interpolation operation on a flat numeric array with null gaps and do not want to spin up a full data-science library or local computation environment. It is best suited for simple 1D sequences where linear estimation between neighbors is sufficient, rather than polynomial, spline, or time-aware interpolation.

## Known failure modes

- Array contains only nulls with no anchor values — cannot interpolate without at least two non-null boundaries
- Input array is empty — returns error or empty result
- Non-numeric (non-null) values in the array may cause a type error
- Leading or trailing nulls with no bounding known values cannot be extrapolated and may remain null or cause an error
- Malformed request body missing the 'values' key returns a validation error

## Output

Returns a JSON object with a 'result' field containing the processed array where null values have been replaced with linearly interpolated numbers based on surrounding known values, and a 'status' field confirming success.
