K-2SO Decision Procedure for Agents Paying for Long-Running Jobs (x402)
x402
K-2SO Decision Procedure for Agents Paying for Long-Running Jobs (x402) is a paid API for AI agents from k2so.wrong.systems, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-13).
Returns a plain-prose decision procedure guiding AI agents through the payment lifecycle for async/long-running x402 job payments, generated on-demand via LLM or deterministic logic.

How this service works
Deterministic procedure for an agent that must pay for a long-running or asynchronous job over x402/MPP (video generation, scraping, inference, batch processing). Covers: submit-payment split (pay only for submission, never for the whole job up front), polling budget with max polls and max total spend across polls, cancel-before-completion refund thresholds, resume-after-timeout rules with re-payment guardrails, job-status code interpretation (queued/running/succeeded/failed/canceled), and a
Output
A JSON object containing a boolean success flag, payment confirmation, and a result object with 120+ words of plain-prose decision procedure text tailored to async/long-running x402 job payments. Includes the model used for generation, the topic, service slug, ISO-8601 generation timestamp, and generation source (llm, reasoning, or deterministic).
Example use cases
Async job payment lifecycle guidance
“My agent just triggered a long-running data processing job via x402 and isn't sure whether to pay upfront or wait — can you give me the full decision procedure for managing async x402 job payments?”
Building an agent that handles 402 retries
“I'm building an autonomous agent that calls slow APIs and I need a clear decision procedure for how it should handle the HTTP 402 payment flow when the job might take minutes to complete.”
Auditing agent payment logic for compliance
“Can you generate the decision procedure for how an AI agent should reason about paying for long-running x402 jobs, so I can compare it against our current agent implementation and spot any gaps?”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/decision-procedure-for-agents-paying-for-long-ruWhen to prefer
Use this endpoint when an AI agent needs authoritative, on-demand prose guidance for navigating the payment lifecycle of async or long-running x402 jobs, especially when the agent must decide timing, retry logic, and settlement confirmation steps. Prefer this over static documentation when you need a fresh, model-generated procedure that can be parameterized by topic. Best suited for agent orchestration layers that inject decision procedures at runtime.
Side effects
- Payment not settled — returns HTTP 402 with PAYMENT-REQUIRED header and exact USDC amount needed
- Invalid meta parameter value — schema validation error
- Service unavailable — upstream LLM or deterministic generator unreachable
- Malformed retry signature — payment signature rejected on retry
- Topic override too long or invalid — may return schema error or truncated result
