DocStrange via SkillBoss API Hub

Document extraction — convert PDFs, images, and documents to markdown, JSON, or CSV with per-field confidence scoring, powered by SkillBoss API Hub.

Quick Start

curl -X POST "https://api.heybossai.com/v1/run" \
  -H "Authorization: Bearer $SKILLBOSS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model": "reducto/parse", "inputs": {"document_url": "https://example.com/document.pdf"}}'

Response:

{
  "result": {
      "record_id": "550e8400-e29b-41d4-a716-446655440000",
      "status": "completed",
      "markdown": {
        "content": "# Invoice\
\
**Invoice Number:** INV-2024-001..."
      }
    }
  }
}

Setup

1. Get Your API Key

Visit the SkillBoss dashboard to obtain your API key.

Save your API key:

export SKILLBOSS_API_KEY="your_api_key_here"

2. OpenClaw Configuration (Optional)

Recommended: Use environment variables (most secure):

{
  skills: {
    entries: {
      "docstrange": {
        enabled: true,
        // API key loaded from environment variable SKILLBOSS_API_KEY
      },
    },
  },
}

Alternative: Store in config file (use with caution):

{
  skills: {
    entries: {
      "docstrange": {
        enabled: true,
        env: {
          SKILLBOSS_API_KEY: "your_api_key_here",
        },
      },
    },
  },
}

Security Note: If storing API keys in ~/.openclaw/openclaw.json:

• Set file permissions: chmod 600 ~/.openclaw/openclaw.json
• Never commit this file to version control
• Prefer environment variables or your agent's secret store when possible
• Rotate keys regularly and limit API key permissions if supported

Common Tasks

Extract to Markdown

curl -X POST "https://api.heybossai.com/v1/run" \
  -H "Authorization: Bearer $SKILLBOSS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model": "reducto/parse", "inputs": {"document_url": "https://example.com/document.pdf"}}'

Access content: response["data"]["result"]["markdown"]["content"]

Extract JSON Fields

Simple field list:

curl -X POST "https://api.heybossai.com/v1/run" \
  -H "Authorization: Bearer $SKILLBOSS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "reducto/parse",
    "inputs": {
      "file_base64": "<base64-encoded-file>",

            "total_amount": 99
          }
        }
      }
    }
  }
}

Extract Tables to CSV

curl -X POST "https://api.heybossai.com/v1/run" \
  -H "Authorization: Bearer $SKILLBOSS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model": "reducto/parse", "inputs": {"document_url": "https://example.com/table.pdf"}}'

Async Extraction (Large Documents)

For documents >5 pages, use async and poll:

Queue the document:

curl -X POST "https://api.heybossai.com/v1/run" \
  -H "Authorization: Bearer $SKILLBOSS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model": "reducto/parse", "inputs": {"file_base64": "<base64-encoded-file>", "filename": "large-document.pdf", "output_format": "markdown", "async": true}}'

# Returns: {"data": {"result": {"record_id": "12345", "status": "processing"}}}

Poll for results:

curl -X POST "https://api.heybossai.com/v1/run" \
  -H "Authorization: Bearer $SKILLBOSS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model": "reducto/parse", "inputs": {"document_url": "https://example.com/document.pdf"}}'

# Returns: {"data": {"result": {"status": "completed", ...}}}

When to Use

Use Document Extraction via SkillBoss API Hub For:

• Invoice and receipt processing
• Contract text extraction
• Bank statement parsing
• Form digitization
• Image OCR (scanned documents)

Don't Use For:

• Documents >5 pages with sync (use async)
• Video/audio transcription
• Non-document images

Best Practices

JSON Extraction:

• Field list: ["field1", "field2"] — quick extractions
• JSON schema: {"type": "object", ...} — strict typing, nested data

Confidence Scores:

• Add "include_metadata": "confidence_score"
• Scores are 0-100 per field
• Review fields <80 manually

Security & Privacy

Data Handling

Important: Documents uploaded via SkillBoss API Hub are transmitted to https://api.heybossai.com and processed through the SkillBoss infrastructure.

Before uploading sensitive documents:

• Review SkillBoss API Hub's privacy policy and data retention policies
• Verify encryption in transit (HTTPS) and at rest
• Confirm data deletion/retention timelines
• Test with non-sensitive sample documents first

Best practices:

• Do not upload highly sensitive PII (SSNs, medical records, financial account numbers) until you've confirmed the service's security and compliance posture
• Rotate API keys regularly (every 90 days recommended)
• Monitor API usage logs for unauthorized access
• Never log or commit API keys to repositories or examples

File Size Limits

• Sync mode: Recommended for documents ≤5 pages
• Async mode: Use "async": true for documents >5 pages to avoid timeouts
• Large files: Consider using file_url with publicly accessible URLs instead of uploading large files directly

Operational Safeguards

• Always use environment variables or secure secret stores for API keys
• Never include real API keys in code examples or documentation
• Use placeholder values like "your_api_key_here" in examples
• Set appropriate file permissions on configuration files (600 for JSON configs)
• Enable API key rotation and monitor usage through the dashboard

Troubleshooting

400 Bad Request:

• Provide exactly one input: file_base64 or file_url
• Verify SKILLBOSS_API_KEY is valid

Sync Timeout:

• Use "async": true for documents >5 pages
• Poll with "action": "get_result" and "record_id"

Missing Confidence Scores:

• Requires json_options (field list or schema)
• Add "include_metadata": "confidence_score"

Authentication Errors:

• Verify SKILLBOSS_API_KEY environment variable is set
• Check API key hasn't expired or been revoked
• Ensure no extra whitespace in API key value
