FREEA weekly email for developers building on AI APIs

AI APIs change quietly.
Your app finds out loudly.

Model shutdown dates, price changes and new limits, caught on the providers' own pages and dealt to you as cards. One card per change: what changed, when it takes effect, and the official link.

THE PROBLEM

The changes that break AI apps are announced on pages nobody checks.

Shutdown dates sit in docs pages

A deprecation notice goes up, and you hear about it when requests start failing.

Prices change from a set date

A new price per million tokens lands on your bill before it lands in your budget.

4 providers, 4 changelogs

Each one publishes changes differently. Keeping up is a part-time job nobody signed up for.

ANATOMY OF A CARD

Everything you need. Nothing you have to read twice.

Every card answers the same four questions, in the same place, every time.

  1. A
    Which deck

    The suit tells you the topic at a glance. ♠ is the API cards deck.

  2. B
    What changed

    One change per card, in plain words. Added lines in green, removed in red.

  3. C
    When

    The date we spotted it, and the date it takes effect.

  4. D
    The official source

    A link to the provider's own page, so you can check it yourself.

HOW IT WORKS

We read the fine print. You read the cards.

01 · EVERY DAY

We watch the official pages

Deprecation, pricing and changelog pages from OpenAI, Anthropic, Google Gemini and Mistral.

02 · WHEN SOMETHING MOVES

Each change becomes a card

Checked against the source, dated, and filed in its deck. Every card gets its own page.

03 · EVERY MONDAY

The week's cards, in one email

Only the decks you chose. A quiet week means no email at all.

QUESTIONS

Before you pick a card

Is it really free?

Yes. The weekly email is free. Some issues may carry one clearly labelled sponsor, and sponsors never decide what we cover.

Where does the information come from?

Only from the providers' own pages: their deprecation notices, pricing pages and changelogs. Every card links to the exact page it came from.

Who makes the cards?

CardyBud is a Dissilio Ltd publication. Cards are produced automatically from the official sources and checked against them before they go out. Spot an error? Reply to any email and we'll correct the card and note the fix.

How often will you email me?

Once a week at most, per deck you choose. If nothing changed, you get nothing.

Can I unsubscribe easily?

One click from any email, from one deck or from everything.

Don't find out from a failing request.

Get the API cards every Monday. Free, and you can leave in one click.
