Apollo

Searches Apollo's contact database for people using various filters; results capped at 50,000 records and does not enrich contact data. Combining multiple strict filters (organization_ids, person_titles, person_seniorities) can return zero results — start broad and narrow iteratively. Result records may have null email, phone, or organization fields.

Enriches data for up to 10 organizations simultaneously by providing a list of their base company domains (e.g., 'apollo.io', not 'www.apollo.io'). Each call consumes Apollo credits per domain enriched; monitor quota to avoid exhaustion errors.

Use to enrich multiple person profiles simultaneously with comprehensive data from Apollo's database. Each call consumes Apollo credits; avoid re-enriching the same contacts. Responses may include null or missing fields (e.g., email, phone, organization); treat unmatched records as valid 'no match' outcomes, not errors. Heavy use may trigger HTTP 429; respect Retry-After headers.

Tool to check whether the provided Apollo API key is valid and accepted by Apollo (health/auth check). Use when any Apollo endpoint returns 401/403/422 to quickly diagnose invalid/expired keys versus permission scope issues. If this succeeds but other endpoints return 403, it strongly suggests permissioning or master-key scope issues rather than a totally invalid credential.

Tool to retrieve detailed information about a specific account by its Apollo ID. Use when you need to fetch complete account data including company details, contact information, and CRM integration fields.

Retrieves detailed information about a specific contact by its ID. Use this to view contact details including name, email, phone numbers, organization, and custom fields.

Retrieves information about a specific deal by its ID. Use this when you need to view details of a single deal.

Retrieves all labels from Apollo.io, used for organizing contacts and accounts. Call this before APOLLO_CREATE_CONTACT or APOLLO_UPDATE_ACCOUNT to validate label values against the returned list; mismatched labels cause 400/422 errors.

Retrieves all configured opportunity (deal) stages from the Apollo.io account.

Retrieves complete information about a specific organization by its Apollo ID. Use when you need detailed company data including funding, technologies, employee counts, and more.

Tool to bulk create multiple contacts in Apollo with a single API call. Use when you need to create multiple contacts efficiently. Supports up to 100 contacts per request with optional deduplication.

Creates a new account in Apollo.io; a new record is created even if a similar account exists, and provided `owner_id` or `account_stage_id` must be valid existing IDs. The response includes the new account's ID, which can be used directly in subsequent calls.

Creates a new contact in Apollo.io; use `account_id` to link to an organization and `contact_stage_id` for sales stage. Apollo does not auto-deduplicate — duplicate records sharing the same email are silently created; always search via APOLLO_SEARCH_CONTACTS before calling this tool. Requires explicit user confirmation before execution.

Creates a new sales opportunity (deal) in Apollo.io; all provided IDs (`owner_id`, `account_id`, `opportunity_stage_id`) must be valid existing Apollo identifiers. This action has persistent side effects — obtain explicit user confirmation before invoking.

Tool to create a single task in Apollo.io. Use when you need to add a new task to your team's Apollo account for a specific contact. The task will be assigned to a user and includes details like type, status, priority, due date, and optional notes.

Tool to log call records in Apollo from external systems. Use when recording calls made through outside systems like Orum or Nooks; requires a master API key and cannot dial prospects directly.

Creates a new custom field in Apollo.io for contacts, accounts, or opportunities. Use when you need to define additional data fields beyond Apollo's standard attributes.

Adds contacts to a specified Apollo email sequence and returns the contact details. `sequence_id`, `emailer_campaign_id`, and `send_email_from_email_account_id` must be retrieved from Apollo listing/search endpoints before calling this tool — these IDs cannot be inferred from names.

Bulk updates the stage for specified existing Apollo.io accounts, moving them to a valid new account stage.

Updates the ownership of multiple Apollo accounts to a specified user. Use when bulk assigning account ownership to a team member.

Automatically processes asynchronously for more than 100 contacts.
