What Your Agent Can Do

Once connected, your agent can:
1

Search for APIs

“Find an API to enrich this lead by email” → Returns matching APIs from Apollo, Hunter, Fiber, and more
2

Get Details

“What parameters does Apollo’s people/match endpoint need?” → Returns full parameter specs
3

Make Calls

“Use Fiber to enrich [email protected]” → Executes the API call and returns results
