Free AI API credits in 2026: every live route, honestly compared
Free AI API credits are the cheapest way to experiment with frontier models: no subscriptions, no cards, just credits to burn on real prompts. But not all credits are equal. Some are denominated at inflated internal rates, some only work inside one company's app, and some quietly expired last week. This comparison covers every live route we could verify on October 14, 2026: the three that are actually claimable today.
The short version: developers should start with AgentRouter's $50 signup credits, app users in the US or Canada should grab the Meta Muse 1B token referral within 48 hours of joining, and verified students should claim Manus Campus credits. Each one is checked below, with the real math on what the credits are worth and where the catches hide.
The short answer: which free credit route wins
Three live offers, three different shapes. Here is the honest comparison before the details:
| Route | Free offer | What it is really worth | The catch |
|---|---|---|---|
| AgentRouter | $50 in signup credits | Roughly $12.50 of standard API usage (credits spend at ~4x the standard rate) | Invite link required; developer-focused (API keys and IDEs, not a chat app) |
| Meta Muse referral | 1 billion tokens for you and the referrer | About $32 of in-app AI usage | US or Canada accounts only, 18+, code must be redeemed within 48 hours of joining |
| Manus Campus | 1,000 starter credits + 300 free credits daily + 1,000 per referral | Real general-agent runs for coursework and projects | Requires a .edu email from a qualifying academic institution |
AgentRouter: $50 in credits for developers
AgentRouter is a proxied LLM gateway: one API key and one base URL give you access to dozens of models, including Claude Opus 5, GPT 5.6 Sol, and GLM 5.2. New users who sign up through an invitation link get $50 in AI compute credits with no credit card and no student ID, using a GitHub or LinuxDO account. The same key works in Claude Code, Cursor, Trae, and the Cline VS Code extension.
The honest math: the $50 is denominated at AgentRouter's internal conversion rate, where about $1 of actual model usage consumes roughly $4 of credit. So it is closer to $12.50 of provider-rate usage on premium models, which is still a meaningful budget for testing. Run cheaper models like DeepSeek or GLM and the same credit stretches much further.
The stacking angle is where this offer gets serious. Share your own invite link and every friend who registers earns you $100 in credits while they get $50. One referral roughly triples your balance, so the program rewards builders who actually use it with other developers.
Meta Muse: 1 billion free tokens for app users
Meta Muse is Meta's personal AI agent, and new accounts in the United States and Canada can redeem a referral code within 48 hours of joining to receive 1 billion Muse tokens, with the referrer getting 1 billion too. The grant is worth roughly $32 of in-app usage, and there is no credit card involved.
The constraints are the tightest of the three routes. The 48-hour redemption window starts the moment you join, so you cannot sign up now and hunt for a code later. It is US and Canada only, 18 and up, and referral codes have a redemption cap (roughly 30 uses per code), so stale codes from old threads may already be tapped out. And these are in-app tokens for Meta's AI app, not raw API credits you can point at your own code.
Manus Campus: free agent credits for students
Manus runs a Campus Program for students, alumni, and staff of qualifying academic institutions. Sign in with a verified .edu email and you get 1,000 starter credits, 300 free credits refreshed daily, and 1,000 bonus credits for every successful student referral, plus a chance at physical Manus swag. Credits spend exactly like paid credits in the Manus agent, so this is real agent usage for coursework, research, coding, and side projects.
The gate is eligibility: your school has to be on Manus' participating-institution list, or the .edu email will not verify. If yours is missing, you can ask Manus to add your domain. Manus also reserves the right to adjust the credit amounts at its discretion, so treat the published numbers as current but not contractual.
Not a student? Manus separately runs a free-access campaign where free and paid users worldwide can use Manus 2.0 Lite and Manus 2.0 within a daily allowance at no charge, so there is a try-it route for everyone else.
The dead end: Claude Code credits (expired October 7)
Worth mentioning because it still shows up in search results: Anthropic's one-time Claude Code credit grant had a claim deadline of October 7, 2026, and unused balances expired on November 4. The page on this site is archived with an expired banner. If a thread or video from early October still points you at it, the offer is gone; no extension was announced.
How to pick your route
- You build with APIs, agents, or IDEs: take the AgentRouter $50 credit, then stack referrals to keep it going.
- You are in the US or Canada and just joined Meta's AI app: redeem a Muse referral code inside the 48-hour window, before anything else.
- You are a student with a .edu email: check Manus Campus eligibility first; the 300 daily credits compound fast.
- You just want to try frontier models free with zero setup: the Meta Muse route is the least technical, AgentRouter is the most flexible.
- Always confirm the offer on the provider's page before signing up: credit programs change amounts and terms without much warning.

AgentRouter: $50 free API creditsFrequently asked questions
Which free AI API credit offer is the best in 2026?
For developers, AgentRouter's $50 signup credit is the most flexible: one API key, dozens of models including Claude Opus 5 and GPT 5.6 Sol, no card required, and referrals stack $100 each. For non-developers in the US or Canada, Meta Muse's 1B token referral is simpler. For students, Manus Campus adds 300 free credits every day.
Is $50 in AgentRouter credits really $50 of API usage?
Not exactly. The credits use AgentRouter's internal conversion rate, roughly four times standard API pricing, so $1 of actual usage consumes about $4 of credit. It is a generous free trial of frontier models, and cheaper models stretch the credit further.
How long do I have to redeem the Meta Muse referral?
The 1B token referral code must be redeemed within 48 hours of joining, on a US or Canada account, and you must be 18 or older. Codes also have a redemption cap, so use a fresh one.
Can I get free Manus credits without being a student?
The Campus Program's 1,000 starter + 300 daily credits require a verified .edu email from a qualifying institution. Non-students can use Manus' separate free-access campaign, which gives free and paid users worldwide a daily allowance of Manus 2.0 Lite and 2.0 at no charge.
Are there free AI API credits with no signup at all?
Not from any program we could verify. Every live offer requires at least an account (GitHub or LinuxDO for AgentRouter, an in-app account for Meta Muse, a .edu email for Manus). None require a credit card, which is the part that matters.
