## 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 service-gap-detector-5529adec -d '<json body>'
```

Example prompt: Can you run a service gap analysis to check where verified demand from agents is outpacing available provider supply in our marketplace, and tell me which capability categories have the biggest shortages?

## When to prefer this

Choose this endpoint when you need to cross-reference actual verified demand against the real supply of agent service providers to surface concrete capability shortages, rather than doing manual market research or relying on anecdotal signals. It is particularly suited for marketplace operators, agent platform builders, or prospective service providers who want data-driven insight into where the ecosystem is underserved.

## Known failure modes

- Insufficient demand or supply data provided results in an incomplete or empty gap report
- Ambiguous or too-broad capability descriptions may yield low-confidence gap signals
- Empty or malformed JSON input body returns a 400-level error
- Upstream data freshness issues may cause stale gap analysis
- Conflicting demand signals from unverified sources may reduce accuracy of identified gaps

## How this service works

Identify capability shortages from verified demand and provider supply

## Output

Returns a structured report identifying specific capability categories or service types where verified demand exceeds available provider supply, including shortage severity signals and relevant demand/supply metrics per gap identified.
