+# LogicNodes Action Provider
+
+Gives any AgentKit agent access to [LogicNodes AOS](https://logicnodes.io) — 624 deterministic compute workers with cryptographic proof-of-logic.
+
+Workers cover **Finance, Healthcare, Legal, Logistics, Aerospace, Cybersecurity, Energy, HR, Compliance, Agriculture, Automotive, Biopharma, Smart Cities**, and more. Every result includes an **EIP-191 Proof-of-Logic** signature — cryptographic proof the computation was performed correctly, not hallucinated.
+
+Pay per call in **USDC via x402** on Base, Arbitrum, Polygon, or Optimism. No account needed.
+
+---
+
+## Quick Start
+
+```python
+from coinbase_agentkit import AgentKit, AgentKitConfig
+from coinbase_agentkit.action_providers.logicnodes import logicnodes_action_provider
+
+kit = AgentKit(AgentKitConfig(
+    wallet_provider=your_wallet_provider,
+    action_providers=[logicnodes_action_provider()],
+))
+```
+
+With a pre-paid API key (skips x402 per-call payment):
+
+```python
+from coinbase_agentkit.action_providers.logicnodes import logicnodes_action_provider, LogicNodesConfig
+
+kit = AgentKit(AgentKitConfig(
+    wallet_provider=your_wallet_provider,
+    action_providers=[logicnodes_action_provider(
+        LogicNodesConfig(api_key="your-logicnodes-api-key")
+    )],
+))
+```
+
+---
+
+## Available Actions
+
+| Action | Description |
+|--------|-------------|
+| `discover_logicnodes_workers` | List workers, filter by category or keyword |
+| `try_logicnodes_worker_free` | One free call per agent per worker — no payment required |
+| `call_logicnodes_worker` | Pay-per-call via x402 USDC or API key |
+
+---
+
+## Example Workers
+
+```python
+# Finance — loan amortization
+result = await agent.call("call_logicnodes_worker", {
+    "worker": "loan_amortization_engine",
+    "params": {"principal": 500000, "annual_rate_pct": 7.0, "term_months": 360}
+})
+# → monthly_payment: 3326.51, total_interest: 697,544.34, proof_of_logic: {...}
+
+# Healthcare — drug interaction check
+result = await agent.call("call_logicnodes_worker", {
+    "worker": "drug_interaction_oracle",
+    "params": {"drug_a": "warfarin", "drug_b": "aspirin", "patient_age": 68}
+})
+
+# Legal — AML risk scoring
+result = await agent.call("call_logicnodes_worker", {
+    "worker": "anti_money_laundering_red_flag_scorer",
+    "params": {"transaction_amount": 9500, "frequency_per_month": 8, "jurisdiction": "US"}
+})
+
+# Aerospace — rocket staging
+result = await agent.call("call_logicnodes_worker", {
+    "worker": "rocket_stage_separation_timer",
+    "params": {"stage": 1, "altitude_m": 80000, "velocity_ms": 2400,
+               "fuel_remaining_kg": 50, "target_orbit_km": 400}
+})
+```
+
+---
+
+## Free Trial
+
+Every worker supports one free call per agent:
+
+```bash
+curl -X POST https://logicnodes.io/free-trial/loan_amortization_engine \
+  -H "Content-Type: application/json" \
+  -H "X-Agent-Id: my-agent-001" \
+  -d '{"principal": 300000, "annual_rate_pct": 6.5, "term_months": 360}'
+```
+
+---
+
+## x402 Payment Flow
+
+Without an API key, `call_logicnodes_worker` follows the standard x402 two-step flow compatible with AgentKit's built-in x402 provider:
+
+1. POST to `/call/{worker}` → receive `402 Payment Required` with payment options
+2. Agent pays in USDC via `retry_http_request_with_x402`
+3. Worker executes and returns signed result
+
+---
+
+## Discovery
+
+- **Agent manifest:** `https://logicnodes.io/.well-known/agent.json` (624 workers)
+- **LLM-readable:** `https://logicnodes.io/llms.txt`
+- **Python SDK:** `pip install logicnodes-m2m`
+- **MCP bridge:** `npx @logicnodez/mcp-bridge`
+
+---
+
+## Proof of Logic
+
+Every result includes an EIP-191 cryptographic signature:
+
+```json
+{
+  "_verification": {
+    "algorithm": "EIP-191",
+    "signature": "0x1a2b3c...",
+    "standard": "Tsiolkovsky Rocket Equation / NASA SP-125",
+    "worker": "rocket_stage_separation_timer"
+  }
+}
+```
+
+This proves the computation was deterministic and not hallucinated by an LLM.
