Create key Documentation

Working with agentsConnect RedPill to agent frameworks and runtimes.

import OpenAI from "openai";

const client = new OpenAI({
  baseURL: "https://tee.redpill.ai/v1",
  apiKey: process.env.REDPILL_API_KEY,
});

const response = await client.chat.completions.create({
  model: "moonshotai/kimi-k3",
  messages: [{ role: "user", content: "Say hello." }],
});

Check privacy evidence

Follow the receipt from the gateway response to its verified session using four curl requests.

Check the gateway

Fetch the current TEE evidence and check that the keyset has not expired.

curl -fsS "https://tee.redpill.ai/v1/aci/attestation" \
  -H "Authorization: Bearer $REDPILL_API_KEY"

Output

{
  "api_version": "aci/1",
  "workload_keyset_digest": "sha256:4f3dc45e...",
  "attestation": { "workload_keyset": { "not_after": 1790498751, ... }, ... },
  ...
}

Send a private request

The response header contains the receipt ID, not the receipt itself.

curl -fsS -i "https://tee.redpill.ai/v1/chat/completions" \
  -H "Authorization: Bearer $REDPILL_API_KEY" --json '{"model":"moonshotai/kimi-k3","messages":[{"role":"user","content":"Hello"}],"provider":{"aci_verified":true}}'

Output

HTTP/2 200
x-receipt-id: rcpt-e0eefe63b3673e2a5984951f
...

{
  "model": "moonshotai/kimi-k3",
  ...
}

Inspect the receipt

Paste the x-receipt-id above and compare its keyset digest with step 1.

curl -fsS "https://tee.redpill.ai/v1/aci/receipts/REPLACE_WITH_RECEIPT_ID" \
  -H "Authorization: Bearer $REDPILL_API_KEY"

Output

{
  "api_version": "aci/1",
  "receipt_id": "rcpt-e0eefe63b3673e2a5984951f",
  "workload_keyset_digest": "sha256:4f3dc45e...",
  "event_log": [
    ...,
    { "type": "upstream.verified", "session_id": "63c5a08de14e5c5253e6fb29271151f40621beb83b552ccca65772772856053f", "result": "verified", "required": true },
    { "type": "response.returned", "body_hash": "sha256:..." }
  ],
  ...
}

Inspect the session

Copy session_id from the upstream.verified event above, then fetch that session.

curl -fsS "https://tee.redpill.ai/v1/aci/sessions/PASTE_SESSION_ID_FROM_RECEIPT" \
  -H "Authorization: Bearer $REDPILL_API_KEY"

Output

{
  "api_version": "aci/1",
  "upstream_name": "...",
  "verifier_id": "...",
  "claims": { "tee_attested": { "status": "asserted", ... }, ... },
  ...
}
