The agent identifies the workflow to analyze and collects relevant inputs and data sources.

Overview

End-to-end token usage and cost visibility.

Token Estim8r AI Agent analyzes token usage across any AI workflow and estimates related costs end-to-end. It counts prompt and completion tokens, retrieves pricing (static or live via Jina API), and computes total costs per run. It logs results with model details and timestamps for auditing and future optimization.


Capabilities

What Token Estim8r AI Agent does

End-to-end token and cost visibility for every workflow.

01

Analyze the target workflow to identify token-using steps.

02

Estimate prompt tokens for each call.

03

Estimate completion tokens for model responses.

04

Retrieve pricing from static data or live API.

05

Calculate total cost per run and per model.

06

Log token counts, costs, and metadata to a chosen destination.

Why you should use Token Estim8r AI Agent

This AI Agent makes costs visible in real time and enables proactive budgeting. It provides auditable logs and per-run cost details, helping teams defend spend and optimize usage.

Before
High uncertainty about token consumption per run.
Difficulty attributing token usage to specific prompts and workflow steps.
Lack of real-time pricing data leading to budgeting errors.
Manual, error-prone logging not aligned with actual costs.
Inability to isolate costs by model or workflow for budgeting.
After
Accurate per-run token counts across all models and steps.
Transparent cost per run and per model for each workflow.
Auditable logs stored in a central destination.
Optional live pricing that reflects current market rates.
Cost visibility by workflow to support budgeting and optimization.
Process

How it works

A simple 3-step flow anyone can use.

Step 01

Identify target workflow

The agent identifies the workflow to analyze and collects relevant inputs and data sources.

Step 02

Estimate tokens and pricing

The agent counts tokens for prompts and completions and applies static or live pricing to compute costs.

Step 03

Log results and notify

The agent writes results to the chosen destination and can alert stakeholders if thresholds are exceeded.


Example

Example workflow

A realistic scenario showing token estimation in action.

Scenario: A data science team runs a text-generation workflow using a mix of prompts and model responses, averaging 2,500 tokens per run. They deploy Token Estim8r to estimate token counts and costs, log results to Google Sheets, and optionally fetch live pricing from the Jina API. After a day, they review the sheet to identify high-token areas and adjust prompts or models to reduce spend.

FAQ

FAQ

Practical answers to common concerns.

The Token Estim8r AI Agent tracks token usage and estimates costs across your AI workflows. It logs data to your chosen destination and can fetch live pricing from the Jina API. It supports multiple models and can help you budget more accurately.

Live pricing is optional. You can run with static pricing data or enable a live pricing feed via the Jina AI Pricing API to reflect current rates.

The agent is designed to work with token-based LLMs such as OpenAI, Anthropic, and other providers. It can be extended to include additional pricing mappings as needed.

Choose your destination (Google Sheets, Airtable, Notion, SQL database, etc.) and connect it in the Token Estim8r setup. The agent writes per-run token counts, costs, model, and timestamps to the destination you select.

Yes. The agent processes multiple runs in a single workflow analysis, aggregating token counts and costs by run, model, and workflow. It can produce daily or weekly reports and supports incremental logging to your destination.

Security depends on the destination you choose. The agent uses authenticated connections to your data store and respects standard access controls. Data at rest and in transit is protected by the destination’s security measures, and you control who can view logs.

To enable live pricing you must provide your Jina API Auth Header in the pricing node. The agent will fetch current prices for each model and apply them to per-run cost calculations, ensuring up-to-date budgeting.
