OpenAI API credits with ChatGPT Business or Pro: how to claim

In 60 seconds: On October 28, 2026, OpenAI announced up to US$500 per month in API credits for eligible Pro and Business subscriptions. First check whether the offer appears in Billing: OpenAI does not publish a country list for this offer; we cannot confirm availability in LATAM or Spain. Before activating, identify the owner and receiving organization. Then test a small workflow with human review and track usage. Monthly credits expire at the end of the cycle and do not roll over; annually prepaid Business has an annual grant and expiry.

If your small business already pays for ChatGPT Business, or you use Pro as a founder, this benefit may fund an API pilot. Choose a task you can evaluate before expiry, with an owner who can stop it.

The announcement appears in the official October 28 changelog. We checked the amounts, requirements and steps in this guide on October 29, 2026, against OpenAI’s help article and developer guide. The offer may change or be withdrawn. There is no published date for access across all accounts or a model list specific to this promotion.

How much credit can you receive?

These are credit allowances in US dollars, not subscription or seat prices. “Up to US$500” is a maximum subject to eligibility and activation.

Plan or condition	Full-period credit allowance	Verified on	Official source
Pro 100	US$100 per monthly billing cycle	Oct 29, 2026	OpenAI
Pro 200	US$200 per monthly billing cycle	Oct 29, 2026	OpenAI
Pro 500	US$500 per monthly billing cycle	Oct 29, 2026	OpenAI
Business Standard	US$20 per paid seat per month, pooled	Oct 29, 2026	OpenAI
Business Premium	US$100 per paid seat per month, in the same pool	Oct 29, 2026	OpenAI
Monthly Business, both seat types	Combined US$500 cap per workspace per monthly cycle	Oct 29, 2026	OpenAI
Business paid annually upfront	One issuance for the year; US$6,000 cap per annual cycle	Oct 29, 2026	OpenAI

For example, 10 Standard × US$20 + 4 Premium × US$100 = US$600; after the cap, the monthly workspace receives US$500. The pool funds the linked organization: it is not US$500 for each teammate.

The first grant is prorated for the time remaining in the paid billing cycle. If you claim partway through, the displayed amount may be lower than the table; check the amount and date before confirming. The first annually prepaid Business grant is also prorated for the remaining term. Monthly credits expire at cycle end and do not roll over; annual credits expire at annual cycle end. Grant and renewal conditions, checked October 29.

Before claiming: accounts, owners and country

Review this checklist with the person managing the accounts. Requirements checked on October 29 against the official help article:

• Your eligible paid subscription has been active for at least seven days. Plus, Go, Free, Enterprise, Edu, free trials, complimentary subscriptions and legacy Codex seats are excluded.
• The person activating is the owner of the Pro subscription or Business workspace and an owner of the API organization. A Business admin or member role alone is insufficient; API billing-management permission is also required.
• The ChatGPT and API accounts used to link have the same email address.
• You have selected the company’s intended API organization. Linking is 1:1: one subscription or workspace per organization, and one active link per organization. Changing it requires support.
• The benefit appears in Billing. Availability depends on the enabled cohort and country; the help article does not publish a list. API support in a country does not confirm access to this promotion.

As an operational choice, avoid linking the workspace through an employee’s personal account that may leave the company. Document who maintains ownership and corporate access without sharing passwords. OpenAI says the link is removed if the owner who linked the Business workspace leaves it. Plan that departure with support.

If the benefit is missing, check the plan, subscription age, selected workspace, permissions and email. Then contact OpenAI Support. A country list and general enablement date are not published / verify; do not budget the credit until the grant appears in your organization.

How to claim from ChatGPT

Route checked on October 29, 2026, against the official guide:

1. Sign in as the eligible subscription owner; for Business, select the relevant workspace.
2. For Pro, open Settings → Billing. For Business, open workspace billing in ChatGPT or the Admin Console.
3. Find the API credits benefit and start the claim flow.
4. Select the receiving API organization and review the displayed amount.
5. Confirm activation. In API Platform → Billing → Credit grants, check the organization, amount and expiry.

How to claim from API Platform

This route activates the same benefit, according to the same guide, checked October 29:

1. Sign in to API Platform with the same email as ChatGPT.
2. Select the API organization you own and want to link.
3. Open Billing and find the API credits benefit.
4. Select the eligible Pro subscription or Business workspace you own and confirm.
5. Check the grant under Billing → Credit grants in that organization.

If you are new to the API, you can link your Personal API Organization. You do not need to add a payment method to use an active promotional grant. Activation and credit issuance are separate outcomes: if accounts are linked but the grant is missing, check the organization and contact support. Do not send API keys or passwords.

Activate once; subsequent grants arrive when the subscription renews while it remains eligible and the offer stays available. For a first request, follow the official quickstart.

What is covered and excluded?

The coverage guide, checked October 29, includes usage billed to the linked organization: Responses and Chat Completions; Agents API, including OpenAI-hosted sandbox charges; Decisions; GPT-Live and Realtime; Images; and built-in tools such as web search, file search and Code Interpreter, with applicable usage and storage charges.

Codex through API keys is excluded. The benefit does not increase ChatGPT or signed-in Codex limits or the Business workspace credit balance. Business plugin credits are a separate promotion. The documentation describes APIs and products; it does not publish a model list specific to this benefit. Official exclusions.

ChatGPT and API billing remain separate. Review each product in its own settings. A Business seat also does not give a teammate access to the API organization or its projects: grant that access separately.

Four small pilots for a B2B business

These are Kiia pilot proposals, not measured results or credit-to-task conversions. Use synthetic or authorized data and start without write permissions. Give each pilot a separate project and record which outputs a person accepted.

Bounded pilot	Risk to watch	Human review	What to measure alongside project spend
Classify incoming emails or tickets in one inbox and suggest priority	Missing an urgent case or following malicious message instructions	Someone validates category and priority before moving or replying	Corrected classifications, missed urgent cases, calls and retries
Extract invoice or order fields into a draft table	Misreading currency, totals, identifiers or duplicates	Validate against the document before entering anything in the ERP	Accepted documents, corrected fields and cost per accepted document
Summarize authorized CRM or meeting notes	Inventing commitments or dates	The responsible person checks the summary and approves any update	Accepted summaries, corrections and cost per accepted summary
Answer questions over a small internal SOP collection with references	Using an outdated version or exposing another department’s information	The process owner validates answers; the agent escalates when evidence is missing	Verifiable answers, escalations, tools and storage

Open the Usage dashboard, choose the linked organization and period, and select the project using the dashboard’s own selector. Compare consumption with your records of calls and accepted outputs. Dashboard dates use UTC; account for that when comparing local workdays. Repeat this review after each pilot batch. Official usage and cost guide, checked October 29.

Reported spend and cash charged after credits are applied are different measures. Credit grants shows grants and expiry; Usage analyzes activity. Calculate observed consumption per accepted result, including retries, tools and storage. A balance alone cannot tell you how many documents or conversations it will cover.

Controls before leaving a pilot running

1. Separate projects and API keys by workflow and environment. Keep keys on the server, out of browsers and repositories; restrict permissions and data. See the official authentication reference and our guide to secure agent permissions.
2. Configure alerts and an enforced spend limit. In organization or project limits, review Spend → Edit spend limit and Enforce a hard limit. Alerts notify while traffic continues; an enforced limit interrupts requests, though small overages can occur during propagation. Also cap calls, retries and concurrency in your application. Spend-limit documentation, checked October 29.
3. Review Auto Recharge before buying credits. Prepaid setup may enable automatic recharges by default. If you choose to use them, set a threshold, target balance and monthly automatic-purchase cap. That cap does not limit manual purchases or consumption of existing credits. For a pilot without automatic purchases, leave it disabled. Prepaid billing help, checked October 29.
4. Define a fallback when the balance runs out. Promotional credits are consumed first, then purchased credits. With no credits left, requests fail with HTTP 429 credit_balance_exhausted; a 429 can also have other causes. Check the code before retrying or buying more. Rate limits still apply. API errors and rate limits, checked October 29.
5. Assign an owner and closing date. Invite teammates to API projects separately and review the balance before expiry. Keep a manual fallback if the service fails. To budget beyond the credit, include integration, review and maintenance using our real cost of an AI agent guide.

How this fits with other credits and plans

If you are choosing a subscription, read our guide to AI plans and ChatGPT Pro limits. For other programs, see AI startup credits and OpenAI for Startups: credits versus resources. Each has its own terms: do not assume balances can be combined.

Microsoft, AWS and Cloudflare cloud credits cover infrastructure services according to each program. This grant funds API Platform in the linked organization; it is not a general infrastructure budget.

To choose a first workflow and decide what to review before granting access, you can request a Kiia diagnostic. Bring the process, connected systems and criteria for accepting a result; we do not need credentials.
