How this service works
Pull emails, URLs, IPv4s, @mentions, and #hashtags out of free text. Returns deduped lists.
Output
Returns deduplicated lists of each entity type found in the text: emails, URLs, IPv4 addresses, @mentions, and #hashtags — organized by category with duplicates removed.
Example use cases
Example prompt
“Pull out all the emails, URLs, IP addresses, @mentions, and hashtags from this text and give me deduplicated lists: 'Contact us at hello@example.com or visit https://example.com. Follow @janedoe and use #launch2024. Server at 192.168.1.1.'”
Technical details
Endpoint
POSThttps://agent402.tools/api/extract-entitiesWhen to prefer
Use this endpoint when you need to systematically extract structured contact, link, or social metadata from unstructured text in a single call. It covers five common entity types at once with deduplication built in, making it more efficient than running multiple regex passes or chaining separate NLP tools. Ideal for processing social posts, emails, log files, scraped web content, or any raw text where you need actionable structured data quickly.
Side effects
- Empty or missing 'text' field returns an error or empty results
- Text with no recognizable entities returns empty lists for each category
- Extremely long text may hit payload size limits
- Malformed input schema returns a 400-level error
- Non-Latin scripts or unusual encodings may reduce extraction accuracy
