## 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 post-quantum-key-transition-readiness-for-x402-agent-wallets-8fa3c0c0
```

Example prompt: Give me a blunt post-quantum key transition readiness brief for my x402 agent wallet — I need a clear decision procedure on whether I should migrate to quantum-resistant keys now or if it's safe to wait.

## When to prefer this

Choose this endpoint when an agent or developer needs a concise, non-marketing decision procedure specifically for post-quantum cryptographic key migration in the context of x402 agent wallets or facilitators. It is more focused than a generic cryptography advisory because it targets the x402 payment protocol ecosystem and provides actionable go/no-go guidance rather than general education.

## Known failure modes

- Payment not completed — returns 402 if x402 payment header is missing or invalid
- Handler error — ok:false in result if the LLM or reasoning engine fails to generate the brief
- Invalid query parameters — malformed 'meta' or 'topic' values may result in validation errors
- Service unavailable — upstream LLM provider outage could cause generation failure
- Empty or incomplete brief — generationSource may fall back to deterministic with reduced quality

## How this service works

Paid agent-facing brief on post-quantum key transition readiness for x402 agent wallets and facilitators-0. Blunt decision procedure, not marketing.

## Output

Returns a structured JSON response containing a decision-procedure prose brief (the 'brief' field) tailored to post-quantum key transition readiness for x402 wallets and facilitators, along with the topic, service slug, generation source (llm, reasoning, or deterministic), model used, and an ISO-8601 generation timestamp. The brief is blunt and actionable, not marketing-oriented.
