Providers

RedPill routes this private model across verified providers with automatic fallbacks. Pricing is unified, so you pay the same price no matter which provider serves your request, while live metrics show latency and uptime.

import { readFile } from "node:fs/promises";
import OpenAI, { toFile } from "openai";

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

const audio = await readFile("audio.wav");
const response = await client.audio.transcriptions.create({
  model: "mistralai/voxtral-small-24b-2507",
  file: await toFile(audio, "audio.wav"),
});
const transcript = response.text;

Check privacy evidence

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

  1. 1
    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, ... }, ... },
  ...
}
  2. 2
    Send a private request

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

    curl -fsS -i "https://tee.redpill.ai/v1/audio/transcriptions" \
  -H "Authorization: Bearer $REDPILL_API_KEY" \
  -H 'X-ACI-Provider: {"aci_verified":true}' \
  -F 'model=mistralai/voxtral-small-24b-2507' -F '[email protected]'

    Output

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

{
  "text": "Hello.",
  "usage": { "type": "duration", "seconds": 2 },
  ...
}
  3. 3
    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:..." }
  ],
  ...
}
  4. 4
    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", ... }, ... },
  ...
}
