## Before you call it

1. Call `search_suggestions` before using location, technology or industry filters, or the search returns nothing
2. Pass `person_id` values from search into `bulk_enrich_person`, 25 at a time
3. Branch on the body `error_code`, not the HTTP status, which is 400 for most failures
4. Set `enrich_mobile` only when needed. A mobile costs 10 credits against 1 for an email
5. Use Enrich Person. The old Email Finder endpoint was removed in March 2026

## Connect

```bash
curl https://api.prospeo.io/account-information -H "X-KEY: $PROSPEO_API_KEY"
```

```bash
claude mcp add --transport http prospeo https://mcp.prospeo.io
```
