How this service works
Decision procedure for agents and their operators that answers the three questions every auditor asks after an AI agent spends money: who authorized it, what was the ceiling, and who carries the loss when the purchase is wrong. Covers cryptographic proof that an agent, not a human, executed a payment, signing intent with a held Ed25519 key before settlement so future audits can distinguish autonomous execution from manual action. Includes spend-authorization record schema, approval chain
Output
A JSON object containing a plain-prose decision procedure brief (120+ words) generated by an LLM or deterministic source, including the topic, model name, generation source enum (llm/reasoning/deterministic), ISO-8601 timestamp, and service slug. Also includes payment confirmation fields (paid: true, payer address, transaction hash).
Example use cases
Spend gate before each x402 call
“Before my agent pays for any x402 API call, I want it to check a decision procedure that tells it whether the spend is justified and what to log — can you fetch that accountability procedure now?”
Compliance brief for a new agent deployment
“I'm deploying an autonomous agent that will make micro-payments on Base and I need a written decision procedure it can reference to ensure spend accountability — generate that brief for me.”
Escalation logic for an over-budget agent
“My agent has started spending more than expected and I need a clear decision procedure it can follow to decide when to pause, escalate to a human, or continue — pull that procedure from K-2SO.”

Endpoint
GEThttps://k2so.wrong.systems/api/services/agent-facing-decision-procedure-at-the-intersectWhen to prefer
Choose this endpoint when an AI agent needs a ready-made, LLM-generated decision procedure specifically around spend accountability — rather than writing its own logic or calling a general-purpose LLM. It is optimized for agents that need structured, reusable decision prose they can cache and act on, delivered via x402 micropayment without account setup.
Side effects
- HTTP 402 returned if payment not yet settled — must pay exact USDC amount and retry with PAYMENT-SIGNATURE header
- Invalid or missing input.type/method fields cause schema validation errors
- Topic override ignored if not a string
- meta=1 returns free metadata JSON without triggering payment
- Network or provider downtime returns non-200 status
