## 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 sentedge-x402-demand-score-e6ad9537 -d '<json body>'
```

Example prompt: What are the chances that https://sentedge.ai/api/x402-demand/score gets at least one paid call in the next 7 days? Run it through the SentEdge x402 demand scorer.

## When to prefer this

Choose this endpoint when you need a calibrated, data-driven probability estimate specifically for x402-listed resources in the CDP Bazaar ecosystem. It is purpose-built for x402 monetization decisions — such as whether to renew a listing, prioritize promotion, or assess portfolio demand — and outperforms a LightGBM baseline (AUC 0.73 vs 0.67) by incorporating live Bazaar telemetry and eviction timelines. Prefer this over generic API analytics when the resource is actively listed on the CDP Bazaar and you need a single actionable demand signal.

## Known failure modes

- Resource URL not found in current CDP Bazaar catalog — request rejected before payment is charged
- Invalid or malformed resource URL in request body
- Resource was recently evicted from catalog and is no longer scoreable
- Model inference failure or service unavailability returns an error response

## How this service works

Will anyone pay this x402 endpoint? A calibrated probability (0-1) that a listed x402 resource receives at least one paid call in the next 7 days, from a fine-tuned decision model scored against today's CDP Bazaar catalog, plus the listing's live telemetry and days until eviction. ROC AUC 0.73 on held-out hosts and later dates (0.67 for a LightGBM baseline); top-decile scores were paid 65% of the time, bottom-decile 3%. Send {"resource": "<listed x402 resource URL>"}. Resources not in the current catalog are rejected before payment. Method and free demo: https://sentedge.ai/x402-demand/

## Output

A calibrated probability between 0 and 1 indicating the likelihood that the specified x402 resource URL receives at least one paid API call within the next 7 days. The score is produced by a fine-tuned decision model benchmarked at ROC AUC 0.73, incorporating live CDP Bazaar catalog telemetry and days-until-eviction signals. Top-decile scores historically converted to paid calls 65% of the time; bottom-decile only 3%.
