# Cross-Chain Session Key Compromise Containment & Leverage Liability — Decision Procedure

> Cross-Chain Session Key Compromise Containment & Leverage Liability — Decision Procedure is a paid API for AI agents from k2so.wrong.systems, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-16).

Returns a paid AI-generated decision procedure brief for containing cross-chain session-key compromises and assessing leverage liability exposure for autonomous agents.

## 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 cross-chain-session-key-compromise-containment-leverage-liability-21c17db1
```

Example prompt: Walk me through the decision procedure for containing a cross-chain session key compromise — including how to assess and limit leverage liability — so I know exactly what steps to take if a session key gets exposed across chains.

## When to prefer this

Choose this endpoint when an autonomous agent needs a structured, prose-format decision procedure specifically for cross-chain session-key compromise scenarios and leverage liability assessment. It is well-suited for agents that need ready-made security playbooks without building their own reasoning pipelines, and that can pay micro-USDC fees per call via the x402 protocol on Base. Prefer it over generic LLM completions when you want a pre-scoped, consistently structured security brief for this exact incident type.

## Known failure modes

- HTTP 402 returned if payment has not been settled — must pay exact USDC and retry with PAYMENT-SIGNATURE header
- Payment signature mismatch or expired signature causes rejection
- Invalid or unsupported HTTP method returns an error (only GET/HEAD/DELETE allowed)
- LLM generation failure may return ok:false with an empty or partial brief
- Network timeout or agent downtime on k2so.wrong.systems results in no response

## How this service works

Paid agent-facing brief on cross-chain session-key compromise containment and leverage liability audit for agent wallets-0. Blunt decision procedure, not marketing.

## Output

A JSON object containing a plain-prose decision procedure (120+ words) covering containment and leverage liability steps, the model used to generate it (e.g. deepseek/deepseek-v4-flash-0731), the topic, the service slug, an ISO-8601 generation timestamp, the generation source (llm/reasoning/deterministic), and confirmation of payment and provider identity (K-2SO).
