	Apollo	Fiber AI
Pros	+ Massive dataset (210M+ contacts, 30M+ companies) with structured JSON responses — agents get rich firmographic and demographic data in a single call + People Search endpoint does not consume credits, so agents can search and filter freely before committing credits to enrichment + Simple API Key auth via x-api-key header and straightforward REST endpoints make integration trivial for any agent framework	+ First-class agent support — official MCP server, Python/TypeScript SDKs, and dedicated agentic search endpoints that convert natural language to structured filters + Comprehensive OpenAPI 3.1 spec (90+ endpoints) makes tool-use integration trivial for LLM function calling + Unique endpoints competitors lack: reverse email-to-person lookup, real-time LinkedIn live fetch, kitchen-sink enrichment, and GitHub-to-LinkedIn resolution
Cons	- Credit-based pricing adds complexity for agents — different actions cost different credit amounts (1 for email, 5 for mobile), requiring agents to track budget - No official OpenAPI spec, so agents can't auto-discover endpoints or generate typed clients without manual setup	- No permanent free tier — only a 7-day trial, then minimum $300/mo - Auth is non-standard (apiKey in request body for POST, query param for GET) rather than a standard Authorization header, requiring custom handling in generic API clients
