How this service works

Blunt decision procedure, not marketing.
Output
Returns a structured result containing a boolean success flag, a decision procedure brief (prose), the verdict (allow/block/human-escalate) encoded in the brief, the service slug, an ISO-8601 timestamp, and the generation source (llm/reasoning/deterministic). Also includes payment metadata (payer, transaction, selfPay flag).
Example use cases
Autonomous agent spend-policy gate
“My autonomous agent is about to settle an x402 payment for a third-party analytics service — can you screen the merchant offer first and give me an allow, block, or human-escalate verdict based on our spend-policy rules?”
Jurisdiction restriction check before settlement
“Before my agent pays for this offshore content delivery merchant using x402, run a conformance check to see if it violates any jurisdiction restrictions and tell me bluntly whether to proceed or block it.”
Restricted-service flag detection for agent purchases
“My agent wants to purchase access to a financial data feed via x402 — screen that merchant offer against restricted-service flags and let me know if it should be allowed, blocked, or sent for human review.”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/pre-payment-purchase-conformance-screening-for-x?utm_source=zero.xyzWhen to prefer
Use this endpoint when an autonomous agent needs a pre-payment compliance gate specifically within the x402 micropayment ecosystem — particularly when jurisdiction restrictions, restricted-service flags, or spend-policy enforcement are required before settlement. Prefer this over generic policy checks when the decision must be formatted as an actionable allow/block/human-escalate verdict that an agent can act on programmatically without human intervention.
Side effects
- Missing or malformed topic parameter returns a generic or empty brief
- Payment not completed results in 402 response requiring x402 settlement before content is returned
- LLM generation failure may return an error in the result.ok field
- Ambiguous merchant offer description may produce an inconclusive or overly cautious verdict
- Network timeout on k2so.wrong.systems returns no verdict, blocking agent progress
