x402
K-2SO Agent-Side Deterministic Decision Procedure Generator is a paid API for AI agents from k2so.wrong.systems, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-17).
Returns a plain-prose decision procedure (120+ words) for an AI agent buying static files via x402 paid responses, generated deterministically or via LLM.

How this service works
Paid agent-facing brief on agent-side deterministic decision procedure for buying static files via x402 (pay per file, one HTTP header, no account) · Build a decision procedure or schema for: agent-side deterministic decision procedure for buying static files via x402 (pay per file, one HTTP header, no account). Include inputs, thresholds, failure modes. Falsifier: If free docs already solve the decision, paid product fails. Blunt decision procedure, not marketing.
Output
A JSON object containing: a boolean success flag, payment confirmation, the service slug, provider name (K-2SO), and a result object with the full prose decision procedure (120+ words), the topic, model used, generation timestamp, and generation source (deterministic, llm, or reasoning).
Example use cases
Agent static file purchase logic
“My AI agent keeps hitting HTTP 402 on static file endpoints — can you generate a decision procedure it should follow to decide whether to pay and download the file using x402 on Base?”
Onboarding new x402 buying agent
“I'm building a new autonomous agent that needs to buy static files from x402 merchants. Give me a plain-English procedure it should run through before settling any USDC payment for a static file response.”
Auditing agent payment behavior
“I want to review the recommended decision logic for an agent buying static files via x402 — can you pull the current deterministic procedure so I can compare it against what my agent is doing?”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/agent-side-deterministic-decision-procedure-for?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs a ready-made, prose-format decision procedure specifically for evaluating and settling x402 payments for static file purchases on Base (USDC). Prefer it over generic agent guides when you need a machine-readable, timestamped brief that an agent can directly embed into its reasoning loop, and when you are already operating within the x402 payment ecosystem on K-2SO.
Side effects
- HTTP 402 returned if payment not yet settled — agent must pay exact USDC amount and retry with PAYMENT-SIGNATURE header
- Invalid or missing 'input' object in request body returns validation error
- Unsupported HTTP method (e.g. POST) returns 405
- Topic override not recognized may result in generic procedure
- LLM backend unavailable may fall back to deterministic generation source
- Network timeout on wrong.systems infrastructure
