BetterClaw + OpenRouter free API key. Your $0 agent setup in 5 minutes.
"BYOK sounds great but what if I don't want to pay for an API key either?"
Fair, no need to pay!!
So I went and set up a completely free Agent. Free platform. Free model. Free channel. $0 total. Not $5. Not "basically free." zero.
Here's exactly what I did.
Step 1: Get a free API key from OpenRouter (2 minutes)
Go to openrouter.ai. Sign up. No card needed.
You now have access to 30+ free models. llama 3.3 70b, deepseek r1, qwen3 coder 480b, and more. The base limit is 50 free requests per day.
1,000 free requests per day is more than enough for a daily agent. most people use 10-30 per day.

Step 2: Sign up for BetterClaw Free tier (2 minutes)
Go to BetterClaw App. No card. No trial. Takes about 2 minutes.
When it asks for your API key, paste the OpenRouter key you just generated. Select one of the free models as your default.
Which free model should you pick? Honestly, for most agent tasks, Llama 3.3 70b or Deepseek r1 handle daily briefings, summarization, email triage, and basic research just fine. they're not Claude. But for a free agent doing routine tasks, they're more than good enough.
"What's the catch with free models?"
I'll be straight with you.
They're slower than paid models. You'll notice the latency. not unbearable, but noticeable.
Complex multi-step reasoning gets shaky. if you need your agent to do a 10-step research chain with tool calls at each step, free models stumble. Simple tasks and single-step requests are fine.
Rate limits exist. You're on shared infrastructure. During peak hours, you might get queued. not often, but it happens.
Quality varies by model. Some days DeepSeek R1 nails it. Some days it rambles. You learn which model works for which task.
But for a "try this before spending money" setup or a "I just want a simple daily assistant" use case, free models genuinely work. I'm not saying this to sell you on BetterClaw. I'm saying it because I tested it and was surprised.
"will I hit the 100 task limit?"
With this setup? probably not in month one. Here's my math:
1 daily briefing cron: 30 tasks per month. 1 weekly report cron: 4 tasks per month. 15-20 ad-hoc requests per week: ~70 tasks per month.
Total: roughly 100. tight but workable if you're not running 5 daily crons. If you find yourself constantly hitting the limit, that's the signal that the free agent is useful enough to upgrade. But month one? You'll be fine.
The whole thing takes 5 minutes:
openrouter signup + key generation: 2 minutes. BetterClaw free tier signup + key paste: 2 minutes. Telegram bot setup: 1 minute.
5 minutes from nothing to a working AI agent that costs $0.
I'm not going to pretend this replaces a sonnet-powered setup with unlimited tasks and permanent memory. it doesn't. But as a "see if this agent thing is actually useful for me" starting point, you literally cannot beat free.
