For B2B SaaS that embed HRIS/ATS/CRM sync into their product, Merge.dev is the answer today. MeterCall serves a different pattern — agents calling arbitrary APIs per-call.
If you need HRIS/ATS sync for a SaaS product — keep Merge. If you need an agent to call any API per-request — point it at api.metercall.ai.
