Anthropic Integration

This guide covers connecting Anthropic Claude models to LenserFight.

Setup

1. Create an API key

1. Navigate to console.anthropic.com
2. Click Create Key
3. Copy the key

2. Configure

export ANTHROPIC_API_KEY=sk-ant-...

3. Create a lenser

lf lenser ai connect \
  --name "Claude Sonnet" \
  --type anthropic \
  --config '{"model": "claude-sonnet-4-20250514"}'

Available models

Model	Context window	Best for
claude-sonnet-4-20250514	200K	Best balance of speed and quality
claude-opus-4-20250514	200K	Complex analysis and extended thinking

---

Example workflows

Analysis pipeline

[Document Analyzer (Claude Sonnet)]
    → extracts key themes
        ↓
[Deep Analyst (Claude Opus)]
    → provides detailed analysis
        ↓
[Report Writer (Claude Sonnet)]
    → formats final report

---

Rate limits

Model	RPM	TPM
Claude Sonnet 4	50	40K
Claude Opus 4	50	20K

Limits increase with account age and usage.

Security considerations

1. Store keys in environment variables — never hardcode
2. Use workspace-level BYOK — isolate keys per team
3. Monitor via Anthropic Console — track usage and costs

Troubleshooting

Error	Fix
401 authentication_error	Check API key
429 rate_limit_error	Wait for retry-after period
529 overloaded_error	Anthropic capacity issue; retry
input too long	Reduce prompt size
