# External Scientific APIs Tool
The External APIs tool provides access to major scientific databases and repositories, allowing you to search for papers, download datasets, and access real-time scientific data.
## Available APIs
### arXiv Paper Repository
- Search physics papers by category, author, or keywords
- Download PDF files automatically
- Access abstracts and metadata
- Filter by date and relevance
### CERN Open Data
- Access particle physics datasets from LHC experiments
- Download AOD, MINIAOD, and NanoAOD formats
- Filter by experiment (CMS, ATLAS, ALICE, LHCb)
- Access derived datasets and analysis tools
### NASA Data Archives
- Astronomy datasets from Hubble, Kepler, and other missions
- Earth observation data from MODIS and other satellites
- Planetary science data from Mars rovers and probes
- Heliophysics data from solar observatories
### NIST Physical Data
- Atomic and molecular data
- Material properties and constants
- Thermodynamic data
- Spectroscopic databases

## Rate Limits and Best Practices
### API Limits
- **arXiv**: 3 requests per second
- **CERN**: 10 requests per minute
- **NASA**: 1000 requests per hour
- **NIST**: 100 requests per hour
### Optimization Tips
- Cache results locally when possible
- Use specific queries to reduce data transfer
- Batch requests when downloading multiple items
- Respect API terms of service
## Error Handling
- **Network Issues**: Automatic retry with exponential backoff
- **Rate Limiting**: Automatic throttling and queuing
- **Authentication**: Clear error messages for API keys
- **Data Validation**: Ensures downloaded data integrity
## Privacy and Ethics
- **Attribution**: Properly cite downloaded papers and data
- **Fair Use**: Respect copyright and usage policies
- **Data Sharing**: Follow institutional guidelines
- **Academic Integrity**: Use data responsibly in educational contexts
