## 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-mpp-inspired-stableenrich-decision-procedure-builder-01f314a9
```

Example prompt: Build me a plain-prose decision procedure on how an agent should evaluate stablecoin enrichment data quality — I need at least 120 words of structured reasoning I can paste directly into my agent's context.

## When to prefer this

Choose this endpoint when an AI agent needs a ready-made, plain-prose decision procedure or reasoning schema for a specific topic, without building one from scratch. Especially useful when the topic relates to stablecoin enrichment, data evaluation, or agent commerce workflows. Prefer this over general LLM completions when you want a short (120+ word), structured, agent-consumable brief delivered via x402 micropayment at $0.002 USDC — making it cost-effective for high-frequency agent orchestration. Use the meta=1 query param for free metadata inspection before paying.

## Known failure modes

- HTTP 402 returned if no payment header is sent — must settle exact USDC amount and retry with PAYMENT-SIGNATURE
- Invalid or missing 'input' object causes schema validation failure
- Unsupported HTTP method (POST, PUT, PATCH) returns error — only GET/HEAD/DELETE allowed
- Topic override too vague may result in a generic or low-quality procedure
- LLM backend unavailability may cause generation failure or fallback to deterministic source
- Malformed query params (e.g. meta not '0' or '1') may be silently ignored or cause unexpected behavior

## How this service works

Paid agent-facing brief on MPP-inspired: stableenrich · Build a decision procedure or schema for: MPP-inspired: stableenrich. Include inputs, thresholds, failure modes. Falsifier: If free docs already solve the decision, paid product fails.-0. Blunt decision procedure, not marketing.

## Output

Returns a JSON object with ok=true, paid=true, and a result block containing: a plain-prose decision procedure (120+ words) in both 'brief' and 'procedure' fields, the topic label, service slug, the LLM model used (e.g. deepseek/deepseek-v4-flash-0731), an ISO-8601 generatedAt timestamp, and a generationSource enum value (llm, reasoning, or deterministic). Also includes provider='K-2SO' and service slug at top level.
