Logic

Blocks for conditional logic, comparisons, calculations, data sampling, and control flow operations in workflows.

Calculator

What it is

Performs a mathematical operation on two numbers.

How it works

The Calculator block takes in two numbers and an operation choice. It then applies the chosen operation to the numbers and returns the result. If rounding is selected, it rounds the result to the nearest whole number.

Inputs

Input
Description
Type
Required

operation

Choose the math operation you want to perform

"Add" | "Subtract" | "Multiply" | "Divide" | "Power"

Yes

a

Enter the first number (A)

float

Yes

b

Enter the second number (B)

float

Yes

round_result

bool

No

Outputs

Output
Description
Type

error

Error message if the operation failed

str

result

The result of your calculation

float

Possible use case

A user wants to quickly perform a calculation, such as adding two numbers or calculating a percentage. They can input the numbers and operation into this block and receive the result instantly.


Condition

What it is

Handles conditional logic based on comparison operators

How it works

This block compares two values using standard operators (==, !=, >, <, >=, <=) and routes data based on the result. The comparison result determines which output receives data: yes_output for true conditions, no_output for false.

Optionally specify yes_value and no_value to output different data than the input values. If not specified, value1 is used as the output value.

Inputs

Input
Description
Type

"==" | "!=" | ">" | "<" | ">=" | "<="

Value2

Yes

yes_value

(Optional) Value to output if the condition is true. If not provided, value1 will be used.

No

Outputs

Output
Description
Type

error

str

result

bool

yes_output

The output value if the condition is true

Yes Output

no_output

The output value if the condition is false

No Output

Possible use case

Threshold Checks: Route workflow differently when values exceed limits (e.g., order total > $100 triggers approval).

Status Validation: Check if a status equals "complete" or "error" to branch workflow logic.

Numeric Comparisons: Compare scores, counts, or metrics to conditionally trigger actions.


Count Items

What it is

Counts the number of items in a collection.

How it works

The Count Items block receives a collection as input. It then determines the type of collection and uses the appropriate method to count the items. For most collections, it uses the length function. For other iterable objects, it counts the items one by one.

Inputs

Input
Description
Type
Required

collection

Enter the collection you want to count. This can be a list, dictionary, string, or any other iterable.

Yes

Outputs

Output
Description
Type

error

str

count

The number of items in the collection

int

Possible use case

A user has a list of customer names and wants to quickly determine how many customers are in the list. They can input the list into this block and receive the total count immediately.


Data Sampling

What it is

This block samples data from a given dataset using various sampling methods.

How it works

This block extracts a sample from a dataset using various methods: random sampling, systematic sampling (every nth item), or top-N selection. Advanced options include stratified sampling by key, weighted sampling, and cluster sampling.

Configure sample_size to control how many items to select. Use random_seed for reproducible results. The accumulate option collects data before sampling, useful when processing streaming inputs.

Inputs

Representative Subsets: Extract stratified samples from large datasets for analysis or testing.

Performance Testing: Select a smaller sample from large data for workflow development and debugging.


If Input Matches

What it is

Handles conditional logic based on comparison operators

How it works

This block checks if an input matches a specified value and routes data accordingly. When the input equals the value, data flows to yes_output; otherwise, it goes to no_output.

Use yes_value and no_value to specify what data to output in each case. This provides a simple equality check for branching workflow logic.

Possible use case

Category Routing: Route items to different processing paths based on their category or type.

Feature Flags: Check if a feature flag equals "enabled" to conditionally execute new functionality.

Status Handling: Branch workflow based on specific status values like "pending", "approved", or "rejected".


Pinecone Init

What it is

Initializes a Pinecone index

How it works

This block initializes or connects to a Pinecone vector database index. Specify the index name, vector dimension, and distance metric (cosine, euclidean, or dot product) for new indexes.

For serverless deployment, configure the cloud provider and region. The block returns the initialized index name for use with insert and query operations.

Pinecone Insert

What it is

Upload data to a Pinecone index

How it works

This block uploads vectors and associated text chunks to a Pinecone index. Each chunk is paired with its embedding vector, and optional metadata can be attached for filtering during queries.

Use namespaces to organize vectors into logical groups within the same index. The upsert operation adds new vectors or updates existing ones with matching IDs.

Memory Storage: Store conversation history or agent memories as searchable vectors.


Pinecone Query

What it is

Queries a Pinecone index

How it works

This block searches a Pinecone index for vectors similar to a query vector. Specify top_k to control how many results to return, and use namespace to search within a specific partition.

Results include similarity scores and optionally the vector values and metadata. Combined results aggregate the text chunks for easy use in RAG pipelines.

Similar Content: Find products, articles, or media similar to a reference item.


Step Through Items

What it is

Iterates over a list or dictionary and outputs each item.

How it works

When given a list or dictionary, the block processes each item individually. For lists, it keeps track of the item's position (index). For dictionaries, it focuses on the values, using the value as both the item and the key in the output.

Inputs

Required

items

The list or dictionary of items to iterate over

List[Any]

No

items_object

The list or dictionary of items to iterate over

The list or dictionary of items to iterate over

str

No

Outputs

Item

key

Possible use case

Imagine you have a list of customer names and you want to perform a specific action for each customer, like sending a personalized email. This block could help you go through the list one by one, allowing you to process each customer individually.
