## 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 banfenzhong-agent-route-packs-practice-route-371d4f86 -d '<json body>'
```

Example prompt: My user just said they want to practice a difficult conversation about asking for a raise — can you route that intent and give me the exact line to say back to them, plus any conditions where I should escalate or back off?

## When to prefer this

Choose this endpoint when your AI agent needs structured, paid-quality routing instructions for a low-stakes practice or coaching conversation, and you require not just a suggested reply but also guardrails (escalate_if, do_not) and a retry policy — rather than building your own dialogue logic or using a free, unstructured prompt. Use the $0.01 practice tier when the intent is exploratory or skill-building, not crisis or deep-therapy level.

## Known failure modes

- Missing or empty intent field causes validation error
- Ambiguous context may produce a generic or mismatched next_utterance
- x402 payment failure results in 402 response and no routing data
- Network timeout on Railway-hosted service during peak load
- Intent outside practice-level scope may return an incorrect or low-quality route

## How this service works

x402-paid routing APIs: practice $0.01, crisis $0.05, deep $0.10. Returns next_utterance + escalate_if + do_not + retry_policy — not just a free HTML link.

## Output

A JSON object confirming the route with: a ready-to-send next_utterance line for the human, an array of escalate_if conditions, a do_not array of prohibited agent actions, a retry_policy with cooldown and loop/rejection handling, an agent_script for internal agent use, an action label, a tool_url, and a route_id for traceability.
