## 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 fiber-ai-api-fiber-ai-exhaustive-contact-reveal-start-99630136 -d '<json body>'
```

Example prompt: Run an exhaustive contact reveal for Sarah Chen, VP of Engineering at Stripe — use every available source in parallel and get me her verified email and phone number.

## When to prefer this

Choose this endpoint when you need the highest possible contact data coverage for a person and are willing to pay a premium ($0.28) and wait for async results. It runs all enrichment waterfall steps simultaneously rather than sequentially, maximizing the chance of finding a verified email or phone. Use over simpler single-source lookups when completeness matters more than speed or cost.

## Known failure modes

- Person not found in any data source — poll returns empty contact fields
- Invalid or unrecognized person identifier — 400 bad request
- Insufficient credits or payment failure — 402 or 429 error
- Job times out before all waterfall steps complete — poll returns partial results
- Rate limiting on parallel enrichment sources — degraded coverage returned

## How this service works

Maximum-coverage async contact reveal. Runs all waterfall steps in parallel. Poll with /contact-details/exhaustive/poll.

## Output

Returns a job ID or poll token that the agent uses to call /contact-details/exhaustive/poll to retrieve the fully enriched contact record including verified email addresses and phone numbers discovered across all waterfall enrichment sources.
