# K-2SO Agent-Facing Decision Procedure for Procuring AI

> K-2SO Agent-Facing Decision Procedure for Procuring AI is a paid API for AI agents from k2so.wrong.systems, paid per call via x402, $0.002/call, status down (last checked 2026-09-15).

Returns a plain-prose decision procedure brief (120+ words) that guides an AI agent through evaluating and procuring AI services, generated via LLM or deterministic reasoning, paid per-call via x402 USDC on Base.

## 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-facing-decision-procedure-for-procuring-ai-ad8653a5
```

Example prompt: Give me a decision procedure brief on how to procure an AI service — what steps should I follow as an autonomous agent to evaluate and select one to call?

## When to prefer this

Choose this endpoint when an autonomous agent needs structured, plain-prose guidance on how to evaluate and procure AI services — especially in x402/USDC micropayment contexts on Base. Prefer over static documentation when the agent needs a dynamically generated, topic-specific decision procedure it can act on directly. Best suited for agentic pipelines where the agent must reason about which AI capability to purchase next.

## Known failure modes

- HTTP 402 returned if payment not yet settled — agent must pay exact USDC and retry with PAYMENT-SIGNATURE header
- Invalid or missing topic parameter returns a default or generic procedure rather than an error
- Payment amount mismatch causes rejection at the x402 facilitator level
- LLM generation failure may fall back to deterministic source, potentially returning a shorter or less tailored brief
- Network or agent availability issues on Base may delay payment confirmation

## How this service works

Paid agent-facing brief on agent-facing decision procedure for procuring AI video generation via x402 payment flows · Build a decision procedure or schema for: agent-facing decision procedure for procuring AI video generation via x402 payment flows. 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 ok/paid flags, a plain-prose 'brief' field (120+ words) with the full decision procedure, the topic, service slug, ISO-8601 generatedAt timestamp, the model used (e.g. deepseek/deepseek-v4-flash-0731), and a generationSource enum ('llm', 'reasoning', or 'deterministic'). Also includes payment confirmation details (payer address, transaction hash).
