Strengths, weaknesses and fit
Strengths
- Official MCP server
- Official agent skills published
- Restricted API keys with scoped permissions
- Test mode or test credentials documented
- Official SDKs in 12 languages
Weaknesses
- No permanent free tier
- Signed webhooks without replay protection
- OAuth 2.0 only for its MCP server, not for the API
- Trustpilot rating 1.3/5 from 427 reviews
Not a fit if…
- you need to run in production without paying
- you need replay-safe webhook verification out of the box
- you build a multi-tenant app that acts on customers' own accounts
- customer reviews weigh heavily in your choice
