Returns a paid, LLM-generated decision procedure for agents to evaluate and compare live merchant inference costs when buying LLM inference via x402 and MPP payment rails.

## 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 live-merchant-inference-cost-index-for-agent-procurement-e4bc7508
```

Example prompt: Can you pull the live merchant inference-cost index decision procedure so I know the current thresholds and failure modes for buying LLM inference via x402 and MPP rails?

## When to prefer this

Choose this endpoint when an autonomous agent needs a structured, actionable decision procedure — including explicit thresholds and failure modes — for evaluating and comparing live LLM inference costs across x402 and MPP merchant rails, and when free public documentation does not already provide a comparable blunt decision schema. Prefer this over generic LLM pricing pages when the agent must make an unattended, programmatic procurement decision with clear pass/fail criteria.

## Known failure modes

- Payment not received or x402 micropayment rejected — agent does not receive the paid brief
- Free metadata endpoint (meta=1) returns schema only, not the decision procedure
- LLM generation failure causes fallback to deterministic or reasoning generation source
- Stale or cached result if generatedAt timestamp is significantly in the past
- Network or DNS failure reaching k2so.wrong.systems returns no response
- Topic override param produces irrelevant procedure if mismatched to the endpoint's domain

## How this service works

Paid agent-facing brief on live merchant inference-cost index for agents buying LLM inference via x402 and MPP rails · Build a decision procedure or schema for: live merchant inference-cost index for agents buying LLM inference via x402 and MPP rails. Include inputs, thresholds, failure modes. Falsifier: If free docs already solve the decision, paid product fails.-0. Blunt decision procedure, not marketing.

## Output

A JSON payload containing a plain-prose decision procedure (120+ words) covering inputs, cost thresholds, and failure modes for agent procurement of LLM inference via x402 and MPP rails. Includes the model used to generate the procedure, a topic slug, an ISO-8601 timestamp, and the generation source (llm, reasoning, or deterministic). The 'paid' flag confirms successful micropayment via x402.
