Example use cases
Pre-purchase clarification with vendor
“I'm looking at a data enrichment service on the402.ai but I need to know if it handles international addresses. Can you start a conversation thread with the provider and ask about their geographic coverage?”
Negotiate custom pricing terms
“We're interested in that bulk SMS service on the402.ai marketplace, but our volume might qualify us for a discount. Can you reach out to them through a thread and see if they offer volume-based pricing?”
Verify API compatibility
“Can you open an inquiry on the402.ai for the webhook service that caught my eye? I need to ask if it supports both REST and GraphQL endpoints before we commit to it.”
