## 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-batch-contact-reveal-start-cddd1823 -d '<json body>'
```

Example prompt: I have a list of 500 LinkedIn profiles I need verified contact details for — can you kick off a Fiber AI batch contact reveal for all of them and give me the job ID so I can check back on the results?

## When to prefer this

Use this endpoint when you need to enrich contact data (email, phone) for a large number of people (up to 2000) in a single operation and can tolerate async processing. Prefer this over the single-person lookup when dealing with bulk lead lists, CRM enrichment runs, or any scenario where enriching one profile at a time would be too slow or expensive per-call overhead matters.

## Known failure modes

- Batch size exceeds 2000 people limit — request rejected
- Invalid or malformed person identifiers in input list
- Authentication failure — invalid API credentials
- Payment failure — insufficient USDC balance
- Rate limiting — too many concurrent batch jobs
- Partial input validation errors for some records in the list

## How this service works

## Output

Returns a batch job identifier that can be used with the /contact-details/batch/poll endpoint to retrieve enriched contact records (email, phone) for up to 2000 people once the async job completes.
