Integration & FAQ

Frequently Asked Questions

Everything you need to know about integrating TokenEnrich into LangChain & LlamaIndex with deterministic ~240-token payloads.

Integration

How do I install TokenEnrich into LangChain & LlamaIndex?

Simply create an API key in your TokenEnrich console and paste the configuration snippet shown above into your LangChain & LlamaIndex settings. It takes under 3 minutes with zero custom code.

Token Optimization

What is the difference between TokenEnrich and web scraping in LangChain & LlamaIndex?

Web scraping extracts raw HTML (15,000+ tokens) which congests context windows and multiplies prompt costs. TokenEnrich queries the network wire directly, delivering verified B2B firmographics in ~240 clean tokens in 140ms.

Batch Concurrency

Can I run bulk lookups on thousands of domains?

Yes. TokenEnrich offers a parallel batch endpoint (POST /v1/enrich/batch) capable of resolving up to 50 domains simultaneously in under 1 second.
