# Fiber AI — Contact Details (Verified Emails & Phone Numbers)

> Get verified work emails, personal emails, and phone numbers — discovered

> for contacts that are verified and deliverable.

## Who it's for

- **Sales teams** needing verified emails and phones to reach prospects without
  bouncing.
- **Growth & RevOps teams** enriching CRM records with validated contact info at
  scale.
- **Recruiters** revealing candidate contact details for direct outreach.
- **Developers** building enrichment pipelines that need high-throughput,
  validated contact discovery.

## Key capabilities

- **Multi-source waterfall enrichment** — industry-specific waterfalls query
  many data sources in sequence, maximizing coverage.
- **Email bounce detection** — every email is validated before delivery,
  including catch-all addresses that other providers miss.
- **Phone validation** — HLR lookups, CNAM checks, and AI-powered address book
  validation ensure phones are live and reachable.
- **Pay only for valid contacts** — no charge when nothing passes validation.
- **Four tiers** at different points on the cost/speed/yield curve:
  - Lite (cheapest, instant lookup)
  - Quick Reveal (balanced default)
  - Turbo (fastest, premium)
  - Exhaustive (deepest waterfall, async)
- **Batch processing** — up to 2,000 identifiers per request.
- **Webhook delivery** — get notified when async jobs complete.

## Pricing (estimated, subject to volume and plan)

Credits per reveal depend on tier and what you request (work email, personal
email, phone, or bundled all contacts). Default path is **Quick Reveal**.

| Tier | Work email | Personal email | Phone | All contacts |
| --- | --- | --- | --- | --- |
| Lite (cheapest, instant) | 1 | 1 | 2 | 2 |
| Quick Reveal (default) | 2 | 2 | 3 | 5 |
| Turbo | 3 | 3 | 5 | 7 |
| Exhaustive (async) | 5 | 5 | 4 | 12 |

- No charge when validation fails (nothing deliverable returned).
