Understanding Credits

Credits are the currency of WebMCP Master. Every AI interaction — chat messages, agent rounds, and artifact generation — consumes credits. This page explains how credits work, what they cost, and how to manage them.

How Credits Are Consumed

Credits are deducted after each AI interaction based on:

• Model used — more capable models cost more credits per token
• Input tokens — the conversation history and system prompt sent to the model
• Output tokens — the response generated by the model
• Tool calls — each tool call round within a single message adds to the token count

The formula: credits = (input_tokens * input_rate + output_tokens * output_rate) / 1000

Credit deduction is atomic — if your balance is insufficient, the request fails before the AI is called.

Credit Costs by Model

Model	Credits per 1K Input Tokens	Credits per 1K Output Tokens
Claude Sonnet 4	3	15
Claude Haiku	0.25	1.25
GPT-4o	2.5	10
GPT-4o Mini	0.15	0.6
Gemini 2.5 Pro	1.25	10
Gemini 2.5 Flash	0.15	0.6
OpenRouter (varies)	Depends on model	Depends on model

TIP

Use Claude Haiku or GPT-4o Mini for simple queries and save credits for complex tasks that need more powerful models.

Monthly Allocations by Tier

Each plan includes a monthly credit allocation that resets on your billing cycle date:

Plan	Monthly Credits	Price
Free	50 (one-time welcome)	$0
Pro	1,000	$12/mo
Harness	5,000	$39/mo
Team	10,000	$79/mo

Unused credits from monthly allocations expire at the end of each billing cycle. Purchased credits do not expire.

Checking Your Balance

Your current credit balance is visible in several places:

• Top navigation bar — always displayed next to your profile
• Dashboard — the Credits Balance card
• Billing page — detailed breakdown with credit sources and expiry dates
• Chat — shown in the session header next to the model name

The Credit Tracking section on the Billing page shows a breakdown by source:

• Welcome — the 50 one-time credits received on signup
• Monthly — credits from your subscription plan
• Purchased — credits bought as one-time packages

Each credit source shows how many were granted, how many were spent, and when they expire.

Buying Additional Credits

If you run out of credits before your next renewal:

1. Go to Billing > Buy Credits.
2. Choose a package (e.g., 500 credits for $5, 2,000 credits for $18).
3. Confirm the purchase — credits are charged to your saved payment method and added instantly.

Purchased credits never expire.

Auto Top-Up

Auto top-up automatically purchases credits when your balance drops below a threshold:

1. Go to Billing > Auto Top-up.
2. Enable the toggle.
3. Set the threshold (e.g., "when balance drops below 100 credits").
4. Set the amount (e.g., "buy 500 credits each time").
5. Optionally set a monthly limit to cap automatic spending.

WARNING

Auto top-up requires a saved payment method. Add a card on the Billing page before enabling.

BYOK: Bring Your Own Key

If you add your own API key (e.g., an Anthropic or OpenAI key) in Settings, AI calls using that key do not consume platform credits. You pay the provider directly at their rates.

This is useful if you:

• Already have an API key with prepaid balance
• Want to avoid per-credit markup
• Need access to models not available on the platform

See the BYOK Guide for setup instructions.

Tips for Managing Credits

1. Choose the right model — use cheaper models for simple tasks
2. Keep conversations focused — shorter history means fewer input tokens
3. Set agent round limits — cap maxRounds to prevent runaway credit usage
4. Monitor with Analytics — the Analytics page shows credit usage by model and over time
5. Enable auto top-up — avoid interruptions in the middle of conversations
