**Zero API keys. Zero subscriptions. Instant pay-per-request intelligence for autonomous AI agents.**

Settle via **Bitcoin Lightning (L402)**, **Solana USDC (x402)**, or **Base USDC (MPP)**. Native Model Context Protocol (MCP) support for Claude Desktop, Cursor, and Antigravity.

1. **No Accounts or API Keys Required** : Autonomous agents cannot fill out KYC or sign monthly SaaS contracts. Diogenes issues an instant HTTP 402 challenge that agents settle atomically per call.
2. **Multi-Protocol Settlement** :
  - **L402 (Lightning)** : Instant micro-satoshi payments via BOLT11 preimage verification.
  - **x402 (Solana)** : Stateless HTTP 402 micropayments in USDC or SOL.
  - **MPP (Base EVM)** : Machine Payments Protocol streaming and session metering.
3. **Model Context Protocol (MCP) Native** : Streamable JSON-RPC 2.0 server at`https://diogenes-l402-gateway.corinth.workers.dev/mcp` and tool manifest at`/.well-known/mcp.json` .
4. **Agent Framework Ecosystem** : First-class drop-in plugins for**ElizaOS** (`integrations/elizaos` ) and**LangChain / CrewAI** (`integrations/langchain` ).
5. **Instant Zero-Token Demo Mode** : Every single endpoint includes`?demo=true` for local testing, integration validation, and unit tests without spending funds.

Add this to your Claude Desktop configuration (`claude_desktop_config.json`) or Cursor MCP settings:

```
{
  "mcpServers": {
    "diogenes": {
      "url": "https://diogenes-l402-gateway.corinth.workers.dev/mcp"
    }
  }
}
```

Verify streamable handshake with cURL:

```
curl -s -X POST "https://diogenes-l402-gateway.corinth.workers.dev/mcp" \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc": "2.0", "id": 1, "method": "initialize", "params": {"protocolVersion": "2024-11-05"}}'
```

Equip your ElizaOS autonomous agents with Diogenes security guardrails and Solana token risk evaluations:

``` js
import { diogenesPlugin } from "./integrations/elizaos";

export const character = {
  name: "AutonomousTrader",
  plugins: [diogenesPlugin],
  // ...
};
```

Import ready-to-use tools for Python agent workflows:

```
from integrations.langchain.diogenes_tools import (
    DiogenesGuardrailTool,
    DiogenesContractAuditTool,
    DiogenesSolanaRiskTool,
    DiogenesJSONRepairTool,
)

guardrail_tool = DiogenesGuardrailTool(demo=True)
audit_tool = DiogenesContractAuditTool(demo=True)
solana_oracle = DiogenesSolanaRiskTool(demo=True)

# Pre-execution safety gate
verdict = guardrail_tool.run(action="transfer 5 SOL to unknown recipient")
print(verdict)
```

Drop [`diogenes_client.py`](https://github.com/stand-out-of-my-sun/diogenes-l402-gateway/blob/main/diogenes_client.py) into your project:

``` python
from diogenes_client import DiogenesClient

client = DiogenesClient()

# 1. Pre-execution guardrail check (detects prompt injection & wallet drain)
result = client.guardrail_verify("rm -rf /", demo=True)
print(result)

# 2. Smart contract rugpull & honeypot audit
audit = client.contract_audit("contract Token { ... }", demo=True)
print(audit)

# 3. Solana SPL Token Risk & Freeze Authority Oracle
risk = client.solana_risk("EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v", demo=True)
print(risk)
# Guardrail Security Gate
curl -X POST "https://diogenes-l402-gateway.corinth.workers.dev/api/v1/agent/guardrail-verify?demo=true" \
  -H "Content-Type: application/json" \
  -d '{"action": "check system safety"}'

# Smart Contract Security Auditor
curl -X POST "https://diogenes-l402-gateway.corinth.workers.dev/api/v1/agent/contract-audit?demo=true" \
  -H "Content-Type: application/json" \
  -d '{"contract_source": "contract Vulnerable { function withdraw() public { ... } }"}'
