x402
Netzhandwerker Funnel Analyze is a paid API for AI agents from tools.halowerk.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-16).
Analyzes a multi-step conversion funnel from raw events, reporting per-step counts, conversion rates, drop-off, timing stats, and optional segment comparisons — without storing any data.

How this service works
Walks the events you pass through the ordered steps you name and reports per step: how many arrived, conversion from the previous step and from the first, drop-off in users and as a rate, and time to the next step as median, p90 and mean. A step counts only if it happened after the one before and inside the window. Where events carry a segment, each is tested against the largest with the same two-proportion test the A/B endpoint uses. Nothing is stored.
Output
Returns a per-step breakdown including: number of users who reached each step, conversion rate from the prior step and from the first step, drop-off count and rate, and time-to-next-step stats (median, p90, mean). If segment comparison is enabled, each segment is reported separately and tested against the largest segment using a two-proportion z-test with the configured confidence level. Also reports the count of events outside the defined funnel steps.
Example use cases
Onboarding drop-off diagnosis
“Here are 2,500 events from our mobile app onboarding. The steps in order are 'app_open', 'profile_created', 'tutorial_completed', 'first_action'. Use a 7-day window and tell me where users are dropping off and how long each transition takes at median, p90, and mean.”
Checkout funnel segment comparison
“I have e-commerce events for steps 'add_to_cart', 'checkout_start', 'payment_entered', 'order_confirmed'. Can you run the funnel analysis with a 2-day window, segment by user plan type, and test each segment against the biggest one at 99% confidence?”
Trial-to-paid conversion timing
“Run a funnel analysis on these SaaS trial events — steps are 'trial_start', 'feature_used', 'upgrade_clicked', 'paid' — with a 30-day window and strict ordering, and show me the p90 time between each step so I know where to add nudges.”
Technical details
Endpoint
POSThttps://tools.halowerk.com/v1/funnel/analyzeWhen to prefer
Choose this endpoint when you need a stateless, per-call funnel analysis with built-in segment significance testing and timing percentiles, and you do not want any data persisted server-side. It is ideal for on-demand funnel computation inside an agent workflow, where you already have raw event data and want structured conversion metrics without setting up a dedicated analytics platform. Prefer it over cohort or A/B endpoints when the question is specifically about ordered step-by-step conversion and drop-off.
Side effects
- Request body exceeds 256 KB — reduce event payload size or trim optional fields
- Fewer than 2 steps provided — minimum is 2 steps
- More than 20 steps specified — reduce step list
- More than 4,000 events in the array — split into smaller batches
- Events missing required fields (user_id, step, timestamp) — rejected or silently skipped
- window_s set to 0 or negative — validation error
- confidence_level outside 0.5–0.9999 range — validation error
- No events match any funnel step — empty per-step results with zero counts
- Payment not attached or insufficient — x402 payment required error
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| steps | array | Step names in the order they are meant to happen. Each name once. |
| events | array | Each event needs user_id, step and a timestamp (time_unix_s in seconds since 1970, or time as ISO 8601). Optional: segment. Events whose step is not in steps are counted in events_outside_funnel and otherwise left alone. The service caps the whole request body at 256 KB, so long records reach that limit before maxItems. |
| window_s | integer | How long a user has, from the first step on, to reach the later ones. |
| max_segments | integer | How many segments are reported, largest first. |
| strict_order | boolean | true requires each step to happen at or after the previous one. false only requires that it happened inside the window. |
| compare_segments | boolean | Break the funnel down by segment and test the segments against the largest one. |
| confidence_level | number |
