## 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 agent-facing-us-federal-regulatory-search-decision-procedure-483ab9e4
```

Example prompt: Before my agent processes a payment for a licensed securities broker, I need to know whether it should first look up current CFR rules — can you generate the federal regulatory search decision procedure for securities payment contexts?

## When to prefer this

Choose this endpoint when an AI agent operating in a regulated US industry (fintech, health data, securities, payments) needs a structured, agent-readable decision procedure for determining whether an action triggers a regulatory lookup before execution. Prefer this over generic legal search tools when you need a pre-built agentic compliance workflow with built-in freshness thresholds, regulator-to-activity mapping, and evidence logging guidance rather than raw document retrieval.

## Known failure modes

- Payment not included or insufficient — returns 402 Payment Required before delivering content
- Invalid or missing 'method' field causes schema validation failure
- Overly broad or ambiguous topic override may yield a generic procedure not tailored to the specific regulatory domain
- Stale or hallucinated regulatory citations possible since content is LLM-generated; agents must apply the freshness thresholds returned in the brief itself
- Service unavailability returns non-200 status with no brief payload

## How this service works

Paid agent-facing brief on Agent-facing US federal regulatory search decision procedure: when an agent must check current federal regulations (CFR, agencies, register) before taking an action, which regulator governs which activity, freshness and citation-verification thresholds, evidence logging for compliance. Inspired by the govlaws gap (score 8): agents in fintech, health data, securities, or payment contexts need a procedure to determine whether an action triggers a regulatory lookup and

## Output

A structured JSON response containing a prose decision-procedure brief for AI agents, including: when to trigger a federal regulatory lookup, which regulator governs which activity type, freshness and citation-verification thresholds to apply, evidence logging requirements for compliance, plus metadata fields for the topic, generation timestamp, model used, and generation source (llm/reasoning/deterministic).
