API Documentation

SamGovScraper

Scrapes tender opportunities from SAM.gov using their REST API.

const scraper =newSamGovScraper(input);
const results =await scraper.scrape();

TedEuScraper

Scrapes tender notices from TED EU using browser automation.

const scraper =newTedEuScraper(input);
const results =await scraper.scrape();

UkFindTenderScraper

Scrapes government contracts from UK Find a Tender using browser automation.

const scraper =newUkFindTenderScraper(input);
const results =await scraper.scrape();

DataProcessor

Utility class for formatting and filtering results.

const processor =newDataProcessor('json');
const formatted = processor.format(data);
// Helper methods
DataProcessor.normalizeTender(tender);
DataProcessor.filterByKeywords(tenders,['IT','cloud']);
DataProcessor.sortByDate(tenders,'desc');
DataProcessor.removeDuplicates(tenders);

Best Practices

1. Rate Limiting: The scrapers include built-in rate limiting. Don't remove delays between requests.
2. Proxy Usage: For high-volume scraping or repeated runs, enable proxy support to avoid IP blocking.
3. Search Strategy: Be specific with search queries to get more relevant results and reduce processing time.
4. Date Ranges: Use date filters to limit scope and reduce unnecessary processing.
5. Keywords: Use keywords to post-filter results for higher relevance.

Error Handling

The actor captures and logs errors from each source separately. If one source fails, others continue processing. A summary of errors is provided in the output.

Performance Tips

• Limit Results: Set maxResults to a reasonable number to reduce processing time
• Narrow Date Range: Use dateFrom and dateTo to focus on recent tenders
• Use Keywords: Pre-filter with keywords to reduce unnecessary data collection
• Disable Debug Mode: Keep debugMode: false for production runs for better performance

Troubleshooting

No Results Returned

• Check if the source website is accessible
• Verify search parameters are valid
• Try with a broader search query
• Check if proxy is needed due to IP blocking

Timeout Errors

• Increase browserTimeout parameter
• Try with fewer results or narrower date range
• Enable proxy support for more reliable connections

Rate Limit Errors

• Reduce maxResults or split into smaller date ranges
• Increase delays between requests (modify scraper code)
• Use Apify residential proxies

Contributions are welcome! Please follow the existing code style and add tests for new features.

Adding a New Source

1. Create a new scraper file in src/scrapers/ (e.g., newSourceScraper.js)
2. Implement the scraper class extending the base pattern
3. Add the scraper to src/main.js in the scrapers map
4. Update input schema in .actor/input_schema.json
5. Add documentation in this README

Roadmap

• Add support for additional databases (France, Germany, Canada)
• Implement contract award extraction for all sources
• Add email notification on new matching tenders
• Create web dashboard for tracking results
• Add machine learning for opportunity relevance scoring
• Implement incremental scraping with state management
