To celebrate Halloween, every model on the Swarms API is 50% off for 24 hours. On top of that, the code SPOOKYPRO gets you your first month of Pro free and SPOOKYPREMIUM takes 50% off your first month of Premium, both valid until November 7, 2026.
Happy Halloween from all of us at Swarms 👻🎃
Halloween is about sharing treats, so this year we're handing out a few to everyone who builds with Swarms. For the next 24 hours, all API usage is half price. And for the next week, two subscription codes get you a free first month of Pro or 50% off your first month of Premium.
Here's what's on offer and how to claim it.
| Offer | What you get | How to claim | Ends |
|---|---|---|---|
| API Flash Sale | 50% off model usage tokens on every model | Automatic, just use the API | 24 hours after the announcement |
| SPOOKYPRO | Your first month of Pro free (100% off) | Enter the code at checkout | November 7, 2026, 11:59 PM PST |
| SPOOKYPREMIUM | 50% off your first month of Premium | Enter the code at checkout | November 7, 2026, 11:59 PM PST |
For 24 hours starting today, October 31, every model usage token on the Swarms API costs half the usual price. The discount applies across every model available on the platform, so it doesn't matter whether you're running a single agent, a large multi-agent swarm, or a batch job.
There's no code to enter. Run your workloads as you normally would and the 50% discount is applied to your token usage automatically.
The sale ends 24 hours after our announcement, so this is a good window to:
Don't have an API key yet? Create one on the Swarms Cloud in under a minute and start building.
We're also running limited-time deals on Swarms subscriptions for anyone who wants to start on Pro or move up to Premium.
Use the code SPOOKYPRO at checkout to get your first month of Pro completely free (100% off).

Use the code SPOOKYPREMIUM at checkout to take 50% off your first month of Premium.
Premium normally costs $100 a month and is built for production workloads. It includes everything in Pro plus 2,000 requests per minute, 100,000 requests per day, 2M tokens per agent, 500 agents per batch, Premium models, SOC 2 compliance, priority region and zone routing, and 24/7 email and Discord support.
Both codes are valid until November 7, 2026, at 11:59 PM PST. You can compare everything included in each plan on our pricing page.
Do I need a code for the API discount? No. The 50% off API usage applies automatically to model usage tokens on every model for 24 hours.
When does the API sale end? 24 hours after the announcement on October 31, 2026.

At Swarms, we think the best treats are the ones you share, and this is our way of giving back to the community that builds with us every day.
From our team to yours, happy Halloween, and thank you for being part of the Swarms community. Here's to more building, creating and growing together.
Every free agent, prompt, tool and bundle on the Swarms Marketplace can now take tips. Users can thank a publisher by card, USDC or SOL without leaving the listing, and publishers get paid through Stripe or straight to their Solana wallet.
A one-hour walkthrough for new visitors to swarms.world: find an agent with Autonomous Filter Search, read its listing, try it in Swarms Chat, pull it into your code through the Marketplace MCP and the Swarms API, and buy a paid listing by card, SOL, or USDC.
A hands-on tutorial: wrap the keyless Open-Meteo weather API in a Python MCP server with FastMCP over Streamable HTTP, test it, add a bearer-token check, ship it in Docker, and publish it on the Swarms Marketplace MCP Portal so agents can find and call it.
