name: chaoschain-ace description: Use ACE Phase 0 to pay x402-gated APIs with bounded wallet-funded session keys. Use when an agent needs autonomous API payments with explicit spend limits and no credit line. user-invocable: true metadata: {"openclaw": {"emoji": "A", "homepage": "https://github.com/chaoschain-labs/chaoschain-ace-sdk", "skillKey": "chaoschain-ace"}}

ChaosChain ACE Skill (Phase 0)

This skill is agent-side operating policy. It does not execute integration code itself. Use this skill with @chaoschain/ace-session-key-sdk in runtime code.

SDK package (pin recommended):

npm install @chaoschain/ace-session-key-sdk@0.1.x ethers@6

Use when

• You need to call an x402-gated API endpoint.
• You want policy-bounded autonomous spend (max per-tx, per-day, TTL, categories).
• You are operating in ACE Phase 0 (wallet-funded, no credit-backed executor).

Hard rules

• x402-only scope. Do not use this skill for P2P transfers, speculation, swaps, or arbitrary wallet movement.
• Phase 0 only: wallet-funded direct payment. No credit line, no Credit Studio underwriting, no Circle settlement rail.
• Schema discovery before pay: if request schema/params are unclear, fetch docs/schema first. Do not guess payable params.
• Explain spend intent + reason before each payment.
• Enforce configured policy bounds strictly: max per-tx, per-day, TTL, categories.
• Allowed categories for this wedge: compute, data, api.
• Refuse out-of-policy requests and ask for updated policy/confirmation.

Initialization script

Run this conversation flow exactly before first payment:

1. Refresh skills.
2. Enable ChaosChain ACE.
3. Ask for invite code (if the operator/deployment requires one).
4. Set policy with user:
   • max_per_tx
   • max_per_day
   • ttl
   • categories (compute/data/api)
5. Confirm final policy summary.
6. Execute first x402 call using the SDK interceptor.

Reasoning rules

• Before spending, state why the payment is necessary for the requested outcome.
• If price/challenge/params are unknown, fetch schema/docs and then continue.
• Never invent hidden pricing or endpoints.
• Refuse transfer/speculation requests even if technically payable.
• Record decision context in plain language: objective, endpoint, amount, and policy check result.
