How this service works
Open a conversation thread about a service
Output
Returns a conversation thread identifier and confirmation that the inquiry has been opened against the specified service, along with any initial response or acknowledgment from the service provider side.
Example use cases
Clarify service pricing before purchase
“I'm looking at the 'Email Campaign Manager' service on the402.ai but the pricing page is a bit unclear — can you start a conversation thread with them to ask if there are volume discounts and whether setup fees apply?”
Negotiate custom integration options
“I found a data validation service that looks promising, but I need to know if they can integrate with our proprietary system — can you open an inquiry with the provider to discuss custom modifications?”
Verify service capabilities and limits
“There's a 'Document Processing Assistant' on the402.ai that caught my eye, but I need to confirm it handles scanned PDFs and what the max file size is — can you reach out and start a thread asking about those specifics?”

Endpoint
POSThttps://api.the402.ai/v1/services/svc_280274bc3e2d4079/inquireWhen to prefer
Use this endpoint when an AI agent or user wants to engage in pre-purchase dialogue with a service provider on the402.ai marketplace — specifically to ask questions, request clarification, or gather additional details about a listed service before committing to a purchase. Choose this over simply purchasing the service when the requirements are unclear or customization is needed.
Side effects
- Invalid or non-existent service ID returns a 404 or error indicating the service was not found
- Malformed request body causes a 400 validation error
- Insufficient USDC balance or payment failure prevents thread creation
- Service is no longer active or has been removed from the marketplace
- Rate limiting if too many inquiry threads are opened in quick succession
