## 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

```

Example prompt: Analyze my ad funnel across Google, Meta, and Email channels — I have 50,000 impressions, 8,000 clicks, 1,200 signups, and 300 purchases — tell me the per-stage conversion rates, drop-off at each step, the overall conversion rate, and which stage is the biggest bottleneck.

## When to prefer this

Use this endpoint when you have raw funnel count data across one or more ad channels and need pure computation — conversion rates, drop-off, loss rates, bottleneck identification — without needing to pull data from an external ad platform. Ideal for agents doing post-hoc analysis of marketing data that has already been collected.

## Known failure modes

- Missing or malformed stage data returns a validation error
- Negative or illogical counts (e.g. more conversions than impressions) may return a computation error
- Empty or null channel arrays may result in partial results with no channel breakdown
- Mismatched stage lengths across channels may cause an error or inconsistent output

## How this service works

Cross-channel conversion funnel over your ad data: per-stage conversion rate, drop-off, loss-rate, overall conversion, the bottleneck stage, and a per-channel breakdown. Pure computation over your inputs.

## Output

Returns per-stage conversion rates, drop-off counts and rates, loss rates, overall end-to-end conversion rate, the identified bottleneck stage with the highest drop-off, and a per-channel breakdown of all the same metrics across the provided ad channels.
