## 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 risk-intelligence-vendor-trust-evaluation-procedure-ac4f4f39
```

Example prompt: Give me a decision procedure for evaluating whether a risk intelligence vendor can be trusted — I need the full step-by-step brief so my agent knows how to vet a new risk data provider before paying for its data.

## When to prefer this

Use this endpoint when an autonomous agent needs a structured, prose-based decision framework for evaluating whether a risk intelligence vendor should be trusted — particularly in x402 micropayment ecosystems where agents buy per-call data from unknown vendors. Prefer this over generic vendor evaluation tools when the context is specifically risk intelligence data providers, on-chain or off-chain, and when the consumer is an AI agent rather than a human analyst.

## Known failure modes

- HTTP 402 returned before payment — agent must settle exact USDC amount and retry with PAYMENT-SIGNATURE header
- Malformed or missing payment signature results in rejection
- Topic override not recognized may produce generic procedure
- LLM generation failure could fall back to deterministic source with less nuanced output
- Network timeout on the k2so.wrong.systems host

## How this service works

Decision procedure for agents buying per-call safety scores, risk scores, and insider-cluster data in USDC. Covers score provenance requirements, onchain ground-truth spot checks, repeated-call consistency tolerance, cross-vendor disagreement rules, staleness gates, override and escalation authority, and a falsifier that stops spend when free onchain data reaches the same decision.

## Output

A JSON object containing a plain-prose decision procedure (120+ words) specifically for evaluating risk intelligence vendor trust. Includes the procedure text, the topic, the model used to generate it, a generation timestamp, and whether the source was LLM, reasoning, or deterministic. Also includes provider confirmation (K-2SO) and payment metadata.
