OneCLI connects AI agents to Apollo.io with an API key. Agents can search Apollo’s people and company database, enrich records, and manage contacts, accounts, deals, tasks, and sequences. The gateway injects the key into requests to api.apollo.io, so your agent never sees it.
In Apollo, go to Settings > Integrations > API keys and create a key. Select only the endpoints your agents need, or turn on Set as master key for full access. See Apollo’s guide: Create API keys.

What a connection can actually reach follows the API key: endpoints you left out when creating the key return permission errors, regardless of what OneCLI allows.
An agent calling the Apollo API through the gateway. No auth header is needed, the gateway adds it:
# Search for people at a company (filters are query parameters)curl -sg -X POST "https://api.apollo.io/api/v1/mixed_people/api_search?q_organization_domains_list[]=example.com&per_page=10"# Enrich a person by emailcurl -s -X POST "https://api.apollo.io/api/v1/people/match?email=jane@example.com"
Access is per agent: grant the connection to each agent that needs it, choosing per tool what runs freely, what needs human approval, and what stays blocked. For example, allow people search but require approval before an agent enrolls contacts in a sequence. Organization rules add guardrails on top, like rate limits. Everything is checked before credential injection, so a blocked request never reaches Apollo.
