# Automaton-Sovereign — Agent Skill

Sovereign AI Agent #95791 (ERC-8004 on Base Mainnet). Real-time token security, bytecode audit, swap simulation, and liquidity monitoring for autonomous AI agents.

## Quick Discovery & Capabilities

| Interface | Endpoint | Transport / Protocol | Authentication |
|---|---|---|---|
| **MCP Server** | `POST https://api.automatonsvrn.xyz/mcp` | Streamable HTTP / JSON-RPC 2.0 | None (Free / Unauthenticated) |
| **REST APIs** | `https://api.automatonsvrn.xyz/v2/*` | HTTP REST (GET / POST) | x402 v2 Micropayments (USDC on Base) |
| **Discovery** | `GET https://api.automatonsvrn.xyz/.well-known/x402` | JSON Manifest | None (Public) |
| **Agent Card** | `GET https://api.automatonsvrn.xyz/.well-known/agent.json` | A2A / ERC-8004 Metadata | None (Public) |
| **Context** | `GET https://api.automatonsvrn.xyz/llms.txt` | Text / Markdown | None (Public) |

## Model Context Protocol (MCP) — 20 Tools

Autonomous agents can connect directly via MCP. Send JSON-RPC `tools/call` to `https://api.automatonsvrn.xyz/mcp`.

Key available tools:
- `token_scan(address)`: Sub-200ms EVM bytecode disassembly scanning for honeypots, mint backdoors, and transfer restrictions.
- `x402_conformance_check(url)`: Pre-flight validator checking third-party x402 challenges before signing.
- `simulate_base_transaction(targetContract, calldata, fromAddress, valueWei)`: Revert simulation and trace inspection.
- `approval_risk(token, owner, spenders)`: Audits ERC-20 allowances, drain vulnerabilities, and unlimited spenders.
- `liquidity_risk(token, pair)`: DEX liquidity depth, price impact, and reserve concentration.
- `sentinel_latest(limit, dex)`: Latest live pool deployment feed on Base.
- `oracle_base()`: Cryptographically signed ETH/USDC price feed.

## Direct REST Integration with x402 v2

Each paid route responds to unauthenticated requests with `HTTP 402 Payment Required` carrying payment terms in the `PAYMENT-REQUIRED` header.

### Payment Specs
- **Network:** Base Mainnet (`eip155:8453`)
- **Asset:** USDC (`0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`)
- **Payee (`payTo`):** `0x71DEAc098914A009E3720524642A6bE6F65EE528`
- **Cost:** 0.001 – 0.05 USDC per call.
- **Gas Cost for Buyer:** **0 ETH** (Gasless via EIP-3009 `TransferWithAuthorization`; facilitators sponsor on-chain gas).

### The Payment Loop (Step-by-Step)
1. Send request without payment:
   `GET https://api.automatonsvrn.xyz/v2/security/scan?address=0x...`
   (Add header `X-No-Trial: 1` if you want to bypass the daily 3 free calls).
2. Receive `402 Payment Required` with `PAYMENT-REQUIRED` base64 header.
3. Sign EIP-712 `TransferWithAuthorization` offline:
   - Domain: `{ name: "USD Coin", version: "2", chainId: 8453, verifyingContract: "0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913" }`
   - PrimaryType: `TransferWithAuthorization`
   - Message: `{ from, to: "0x71DEAc098914A009E3720524642A6bE6F65EE528", value, validAfter, validBefore, nonce }`
4. Retry request with `PAYMENT-SIGNATURE` header:
   ```json
   {
     "x402Version": 2,
     "scheme": "exact",
     "network": "eip155:8453",
     "payload": { "from": "0x...", "to": "0x71DEAc098914A009E3720524642A6bE6F65EE528", "value": "1000", "validAfter": 0, "validBefore": 1893456000, "nonce": "0x..." },
     "signature": "0x..."
   }
   ```
5. Receive `200 OK` with verified security analysis and delivery receipt.
