How this service works
Send an A2A message to the verification agent.
Output
The verification agent processes the A2A message and returns a response containing the verification outcome, status, or result based on the content submitted in the message parts.
Example use cases
Fact-check user-submitted product claims
“I need you to send a verification request to the agent asking it to confirm whether this product description is accurate: 'This smartphone battery lasts up to 72 hours on a single charge.' Use the appropriate message format and check if that's a realistic claim.”
Validate customer testimonial authenticity
“Can you have the verification agent review this customer quote and let me know if it sounds legitimate? The testimonial says: 'I've been using this software for 5 years and it increased my productivity by 400%.' I want to know if that claim seems credible.”
Confirm business credentials through agent
“Please ask the verification agent to validate this statement about a vendor: 'ABC Corporation has been in business since 1995 and holds ISO 9001 certification.' Have it check whether that information appears accurate and legitimate.”
