Lots of data and information is stored behind APIs.

|
|

This page covers all resources available in LangChain for working with APIs.

## Chains

|
|
If you are just getting started, and you have relatively simple apis, you should get started with chains.

|
|
|
Chains are a sequence of predetermined steps, so they are good to get started with as they give you more control and let you
|
|
|
|
|
understand what is happening better.

## Agents
|
|
|
|
|
|
|
|
|
|
Agents are more complex, and involve multiple queries to the LLM to understand what to do.
|
|
|
|
|
The downside of agents are that you have less control. The upside is that they are more powerful,
|
|
|
|
|
which allows you to use them on larger and more complex schemas.
