Rate Limits & Batch Optimization

Standard Rate Limits

Tier Requests/Minute Requests/Day Concurrent Batch Size
Free 10 1,000 2 5
Starter 30 5,000 5 10
Pro 100 25,000 10 25
Enterprise 500 100,000 25 50

Effective Rate Limits with Batching

Tier Individual Calls With Batching (5 calls/batch) Improvement
Free 10/min 50/min 5x
Starter 30/min 150/min 5x
Pro 100/min 500/min 5x
Enterprise 500/min 2,500/min 5x

Batch Optimization Tip: A single POST containing multiple JSON-RPC calls counts as 1 rate-limited request. The LeafEngines Batch node automatically optimizes multiple API calls into single batch requests.

Batch Optimization Examples

  1. Soil + Water + Weather Analysis (3 calls) → 1 batch request (66% reduction)
  2. Multi-County Comparison (5 counties) → 1 batch request (80% reduction)
  3. Full Field Analysis (8 endpoints) → 2 batch requests (75% reduction)

See examples/batch-optimization.json for a complete implementation.

MCP Protocol Integration

LeafEngines implements the Model Context Protocol (MCP), enabling AI agents to discover and invoke agricultural intelligence tools natively.

Claude Desktop Configuration

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "leafengines": {
      "transport": "streamable-http",
      "url": "https://[project].supabase.co/functions/v1/mcp-server",
      "headers": {
        "x-api-key": "ak_sandbox_your_key_here"
      }
    }
  }
}

OpenClaw Integration

LeafEngines appears as a discoverable MCP server in OpenClaw. Agents can:

  • Discover available tools via tools/list
  • Invoke tools with typed parameters
  • Batch multiple operations in single requests

Data Integrity Guarantees

LeafEngines provides formal data integrity guarantees:

  1. Provenance Tracking - Chain of custody from source to decision
  2. Formal Uncertainty - Calibrated confidence intervals on all outputs
  3. Cryptographic Integrity - SHA-256 validation of cached data
  4. Temporal Consistency - Data staleness bounds per data type
  5. Compliance-Ready Audit Trail - SOC 2-aligned logging

Performance Benchmarks

Endpoint P50 Latency P95 Latency Cache Hit Rate
get-soil-data 12ms 45ms 94%
county-lookup 8ms 32ms 97%
territorial-water-quality 85ms 210ms 78%
carbon-credit-calculator 45ms 120ms 85%

Troubleshooting

Common Issues

  1. "Invalid API key" error

    • Verify your key starts with ak_
    • Check for typos or extra spaces
    • Ensure you're using the correct tier configuration

  2. "Network error: No response received"

    • Check your internet connection
    • Verify the API URL is correct
    • Check firewall/network restrictions

  3. Rate limit errors

    • Check your tier's rate limits
    • Implement batch operations for multiple calls
    • Add delay nodes between calls if needed

  4. "County FIPS must be 5 digits"

Debug Mode

Enable detailed logging:

# Start Node-RED with debug logging
node-red --verbose

# Or set environment variable
export DEBUG=node-red-contrib-leafengines*
node-red
