How this service works
Paid agent-facing brief on Agent comms and inbox merchant-contract audit: probe-grounded composite that verifies a paid agent inbox or comms endpoint actually speaks x402 correctly before an agent commits funds · Build a decision procedure or schema for: Agent comms and inbox merchant-contract audit: probe-grounded composite that verifies a paid agent inbox or comms endpoint actually speaks x402 correctly before an agent co-0. Blunt decision procedure, not marketing.
Output
A JSON object containing a boolean success flag, payment confirmation, a plain-prose decision procedure (120+ words) describing how to verify x402 compliance on a comms or inbox endpoint, the topic slug, the LLM model used, generation source (llm/reasoning/deterministic), and an ISO-8601 timestamp. The 'brief' and 'procedure' fields contain the actionable audit logic.
Example use cases
Pre-payment inbox compliance check
“I'm about to let my AI agent subscribe to a paid messaging inbox that claims to support x402, but I want a blunt audit first — can you run the probe-grounded merchant-contract check with a GET request and tell me if it actually implements x402 correctly before any funds go out?”
Vetting a third-party agent comms provider
“We're evaluating a third-party agent comms service for our fleet and need to know if their paid endpoint genuinely speaks x402 — can you generate a decision procedure that audits their merchant contract behavior so we can make a go/no-go call?”
Building an x402 inbox onboarding checklist
“I need a structured decision procedure for onboarding new paid inbox vendors to our agent stack — run the probe-grounded composite audit using GET and give me the full prose procedure so I can turn it into a repeatable checklist.”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/agent-comms-and-inbox-merchant-contract-audit-pr?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to programmatically verify whether a paid inbox or comms endpoint correctly implements x402 before committing funds — particularly when probe-grounded, composite auditing is needed rather than static documentation review. Prefer this over manual inspection or generic API testing tools when operating unattended and needing a structured decision procedure in prose form.
Side effects
- Payment not received — endpoint returns 402 with payment instructions instead of the paid response
- Invalid method supplied (only GET, HEAD, DELETE accepted) — schema validation error
- Backend LLM unavailable — result may fall back to deterministic generation source
- Malformed query parameters — returns error if topic or meta values are outside allowed enums
- Network timeout or service unavailability on k2so.wrong.systems
