API

RedPill provides a unified completion API to all models & providers that you can call directly, or using the OpenAI SDK. Additionally, some third-party SDKs are available.

fetch("https://api.redpill.ai/v1/chat/completions", {
  method: "POST",
  headers: {
    "Authorization": "Bearer <YOUR-REDPILL-API-KEY>",
    "Content-Type": "application/json"
  },
  body: JSON.stringify({
    "model": "z-ai/glm-5.2",
    "messages": [
      {
        "role": "user",
        "content": "What is the meaning of life?"
      }
    ]
  })
})
Verify Evidence

Confidential GPU-TEE responses carry two proof layers you can check yourself: a nonce-bound attestation report for the gateway, and a signed receipt that binds your request and response to an attested upstream session.

# 1. Attest the gateway (nonce-bound, proves which TEE workload serves you)
NONCE="$(openssl rand -hex 16)"
curl -s "https://api.redpill.ai/v1/aci/attestation?nonce=$NONCE" \
  -H "Authorization: Bearer $REDPILL_API_KEY" -o report.json

# 2. Call the model and capture the x-receipt-id response header
curl -s "https://api.redpill.ai/v1/chat/completions" -D headers.txt \
  -H "Authorization: Bearer $REDPILL_API_KEY" -H "Content-Type: application/json" \
  -d '{"model":"z-ai/glm-5.2","messages":[{"role":"user","content":"Hello"}]}' -o response.json
RECEIPT_ID="$(grep -i ^x-receipt-id headers.txt | tr -d '\r' | awk '{print $2}')"

# 3. Fetch the signed receipt, then follow it to the attested session
curl -s "https://api.redpill.ai/v1/aci/receipts/$RECEIPT_ID" \
  -H "Authorization: Bearer $REDPILL_API_KEY" -o receipt.json
SESSION_ID="$(jq -r '.event_log[]|select(.type=="upstream.verified").session_id' receipt.json)"
curl -s "https://api.redpill.ai/v1/aci/sessions/$SESSION_ID" \
  -H "Authorization: Bearer $REDPILL_API_KEY"
