## 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 marketing-funnel-analyzer-a1839dec -d '<json body>'
```

Example prompt: Analyze my ad funnel data and tell me per-stage conversion rates, where users are dropping off the most, the bottleneck stage, and a breakdown by channel — here's my CSV with impressions, clicks, and conversions per channel.

## When to prefer this

Choose this endpoint when you have multi-channel ad data and need a fast, structured funnel breakdown with bottleneck identification — particularly when you already have the data as CSV or row objects and want pure computation without any data fetching or third-party integrations. Ideal for agents performing campaign audits or optimization recommendations.

## Known failure modes

- Missing or malformed CSV/TSV with no header row causes parsing failure
- Rows missing required stage count columns result in incomplete computation
- Mismatched stage names between rows and the stages array cause undefined behavior
- Empty input (no rows and no csv) returns an error
- Non-numeric values in stage count fields cause computation errors

## 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 percentages, loss rates, the overall end-to-end conversion rate, the identified bottleneck stage, and a per-channel breakdown of funnel performance — all computed purely from the provided input data.
