Usage Guidelines

When the user asks to enrich, look up, or find information about companies or people, follow these rules:

1. Check credits first for large operations

Before running bulk enrichment (employee lists, person searches, company searches), call enrich_credit_balance to check the user's remaining credits. Warn them about the estimated cost before proceeding with expensive operations.

2. Choose the cheapest tool that answers the question

• If you already have a professional network URL, use a _profile tool (1 credit) instead of a _lookup tool (2 credits).
• Use enrich_company_id_lookup (0 credits) when you have a numeric company ID.
• Use enrich_company_picture or enrich_person_picture (0 credits) when only the avatar is needed.
• Use enrich_disposable_email (0 credits) to validate emails before spending credits on enrichment.

3. Chain tools efficiently

Many tasks require chaining two or more tools. Follow these common patterns:

• Find a person's work email by role: enrich_role_lookup (get profile URL) then enrich_work_email (get email). Total: 6 credits.
• Find a person's work email by name: enrich_person_lookup (get profile URL) then enrich_work_email (get email). Total: 5 credits.
• Enrich a company from just a name: enrich_company_lookup (get URL) then enrich_company_profile (get full data). Total: 3 credits. Or pass enrich_profile: "enrich" to get both in one call for 3 credits.
• Find decision-makers at a company: enrich_company_lookup (get URL) then enrich_employee_list with boolean_role_search set to the target roles.
• Verify a contact: enrich_disposable_email (free check) then enrich_reverse_email (find the profile).

4. Use the enrich_profile / enrich_profiles shortcut

Several lookup and list tools accept an enrich_profile or enrich_profiles parameter set to "enrich". This returns full profile data inline, saving a separate profile call. Use it when you need full details and not just the URL.

5. Use boolean search syntax correctly

Employee search, company search, and person search support boolean operators in many fields:

• OR / || — match either term: "founder OR co-founder"
• AND — match both terms: "engineer AND manager"
• NOT — exclude: "director NOT assistant"
• Quotes for exact phrases: "'Vice President'"
• Max 255 characters for boolean expressions.

6. Control cache behavior

All profile tools accept use_cache:

• "if-present" — use cached data regardless of age (fastest, cheapest).
• "if-recent" — only use cache if the profile is less than 29 days old.

Default to "if-present" unless the user explicitly needs fresh data.

7. Handle pagination for list endpoints

enrich_employee_list, enrich_student_list, and search tools accept page_size. When enriching profiles inline (enrich_profiles: "enrich"), the max page size drops to 10. Plan accordingly for large lists.

8. Country codes

Several tools accept country/location filters. Always use ISO 3166-1 alpha-2 codes (e.g., us, gb, de, sg). For person search, the country parameter is required.
