Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 onchainpulse-scenario-modeling-api-872e18a8
```

Example prompt: Run an if/then sector-impact scenario for me: if the GENIUS Act passes in its current form, what happens to stablecoin issuers, payment processors, and DeFi protocols — give me the strategic and compliance implications for each sector.

## When to prefer this

Choose this endpoint when you need structured if/then impact analysis for a specific regulatory change, legislative development, or institutional action affecting onchain finance sectors — particularly for strategy or compliance workflows where downstream effects across multiple sectors need to be mapped. Prefer this over generic news summarizers or regulatory briefing endpoints when you need scenario branching and sector-specific impact modeling rather than plain-English explanations.

## Known failure modes

- Unrecognized or too-vague scenario trigger returns a 400 with a prompt to clarify the regulatory event
- Out-of-scope non-regulatory scenarios may return empty or low-confidence results
- Payment not received or x402 flow incomplete results in 402 Payment Required
- Rate limiting or capacity issues return 429 Too Many Requests
- Ambiguous sector scope with no recognized entities may return partial results with low coverage warnings

## How this service works

If/then sector-impact modeling for regulatory and institutional developments. For strategy and compliance agents.

## Output

Returns structured if/then scenario output mapping a given regulatory or institutional trigger to downstream sector impacts, including affected industries, strategic implications, compliance risks, and probability-weighted outcome branches for strategy and compliance decision-making.
