Working on a college project and really want to get my hands on the Claude 5.5 Opus API—it’s a beast. Anyone know a solid way to get access? Thanks in advance!

# THE NEWEST CLAUDE, ON THREE DOORS THAT ASK YOU NOTHING 💎 🟢 ✅

 ![three doors, one model, endpoints on the box](https://onehack.st/uploads/default/original/3X/6/c/6c4df2dba10a09957820e11f51012b2dcb46f802.png)

**🟢 CLOUDFLARE WORKERS AI** — 10 000 neurons a day, free

```auto
BASE_URL = https://api.cloudflare.com/client/v4/accounts/$CF_ACCOUNT_ID/ai/v1
MODEL = anthropic/claude-opus-5.5

curl $BASE_URL/messages \
  -H "Authorization: Bearer $CLOUDFLARE_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"model":"anthropic/claude-opus-5.5","max_tokens":1024,
       "messages":[{"role":"user","content":"hey"}]}'

```

**💎 AWS BEDROCK** — $100 at signup, up to $200

```auto
BASE_URL = https://bedrock-mantle.us-east-1.amazonaws.com/anthropic
MODEL = anthropic.claude-opus-5-5

curl $BASE_URL/v1/messages \
  -H "Authorization: Bearer $AWS_BEARER_TOKEN_BEDROCK" \
  -H "Content-Type: application/json" \
  -d '{"model":"anthropic.claude-opus-5-5","max_tokens":1024,
       "messages":[{"role":"user","content":"hey"}]}'

```

**✅ PUTER** — free tier, one script tag

```auto
MODEL = anthropic/claude-opus-5-5
puter.ai.chat("hey", { model: "anthropic/claude-opus-5-5" })

```

**why this is rare**
  
Anthropic shipped Opus 5.5 on **22 sep 2026** — **`$4 / $20`** a million, 1M context.  
**35 companies** now sell it. 🟢 is the one worth knowing: Cloudflare publishes the  
exact list of models that need a paid billing method. Seven names. Kimi, GLM, DeepSeek.  
**Claude is not one of those seven** — so the whole Anthropic catalogue rides free.
