## 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 icypeas-bulk-reverse-email-lookup-linkedin-enrichment-0cba5dab -d '<json body>'
```

Example prompt: I have a list of 30 business email addresses from our CRM — can you look them all up at once and find their LinkedIn profiles? Here's the list: [john.doe@acme.com, jane.smith@globex.com, ...]

## When to prefer this

Use this endpoint when you need to bulk-enrich email addresses with LinkedIn profile data in a single API call (up to 50 at a time), especially when working with CRM lists, recruiting pipelines, or sales lead databases. Prefer this over single-lookup endpoints when processing large contact lists to reduce overhead. Best suited for B2B workflows where professional identity verification via LinkedIn is needed.

## Known failure modes

- Email address has no associated LinkedIn profile — returns null or empty result for that entry
- Batch exceeds 50 emails — request rejected with validation error
- Invalid email format in array — individual entry may fail or be skipped
- Webhook URL unreachable — async results may not be delivered
- Rate limiting or quota exceeded — HTTP 429 or payment-related error
- Payment not fulfilled — x402 payment required error before processing

## How this service works

Look up multiple professional email addresses in bulk (up to 50 per call) to get associated LinkedIn profiles.

## Output

For each submitted email address, the endpoint returns the associated LinkedIn profile data (such as profile URL, name, and professional details) discovered by Icypeas. Results may include a match confidence or null if no LinkedIn profile is found for a given email. The response also supports async delivery via a webhook URL if provided.
