# K-2SO Agent Decision Procedure: When Agents Should Pay for Managed Co

> K-2SO Agent Decision Procedure: When Agents Should Pay for Managed Co is a paid API for AI agents from k2so.wrong.systems, paid per call via x402, $0.002/call, status down (last checked 2026-10-31).

Returns an LLM-generated or deterministic prose decision procedure guiding AI agents on when they should pay for managed co-execution or co-processing services via x402

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability k-2so-agent-decision-procedure-when-agents-should-pay-for-managed-co-eb227164
```

Example prompt: Give me the K-2SO decision procedure for when I, as an autonomous agent, should pay for managed co-execution services — I want the full prose guidance on the criteria and conditions that justify making that payment.

## When to prefer this

Choose this endpoint when an autonomous agent needs structured, prose-form policy guidance specifically on the question of when to pay for managed co-execution or co-processing services in an x402 payment context. It is distinct from generic decision procedures on other topics (market scans, RWA evaluation, etc.) and is specifically scoped to managed co-execution spend governance. Prefer it over building custom heuristics when you want an LLM-generated or deterministic answer that can be cited and audited.

## Known failure modes

- HTTP 402 returned before payment — agent must settle exact USDC and retry with PAYMENT-SIGNATURE header
- Incorrect payment amount causes repeated 402 loops
- topic override parameter ignored if malformed string
- meta=1 returns free metadata JSON instead of paid procedure — agent may mistake this for the full result
- Stale or deterministic procedure returned if LLM unavailable (generationSource will indicate 'deterministic')
- Network timeout on k2so.wrong.systems — no fallback endpoint

## How this service works

Paid agent-facing brief on Agent-facing decision procedure: when agents should pay for managed comms/inbox APIs (paysponge-style paid agent inboxes, threads, message delivery) versus free channels, with deterministic thresholds-0. Blunt decision procedure, not marketing.

## Output

A JSON object with ok/paid flags, a provider field set to 'K-2SO', a service slug, and a result object containing: a 'brief' field with 120+ words of plain-prose decision procedure guidance, the model used (e.g. deepseek/deepseek-v4-flash-0731), the topic string, an ISO-8601 generatedAt timestamp, and a generationSource enum ('llm', 'reasoning', or 'deterministic').
