Not in between. # One endpoint to attested LLMs. A private LLM API: one attested endpoint on top of attested GPUs, OpenAI and Anthropic compatible. GLM, Kimi, DeepSeek and Qwen in Claude Code, Cursor or any compatible client. Paid in USDC. No card, no account. - [I'm a human](#three-steps-then-it-runs) - [I'm an agent](/agents.md) Freight prepaid: USDC, no account. Got an agent? Hand it this: ```text Read https://sealedin.ai/agents.md and set up SealedIn as the model endpoint. ``` ## Three steps. Then it runs. ### 01 Pay Choose 20 to 100 USD and pay in USDC on Solana from a wallet: scan the QR or open the wallet link. Credits never expire. They are not refundable, not withdrawable and not transferable. ### 02 Take the key Save the code shown with the payment. The key appears on this page once the payment confirms, shown once. The code recovers it. Anyone holding the code or the key can spend your balance. [Models and prices](/models.md) ### 03 Run Claude Code: ```bash export ANTHROPIC_BASE_URL=https://api.sealedin.ai export ANTHROPIC_AUTH_TOKEN=$SEALEDIN_KEY export ANTHROPIC_MODEL=chutes/zai-org/GLM-5.2-TEE claude ``` [Claude Code, Cursor and other clients](/claude-code.md) ## Not to be opened in transit. Your request is encrypted all the way and opened only inside sealed hardware: first our gateway, then the GPU running the model. We see spend per key, not your requests.

[What is verified, and what is not](/trust.md) # SealedIn An attested API endpoint on top of attested GPUs: open-weight models, requests encrypted all the way and opened only inside sealed hardware (Intel TDX gateway, GPU enclaves). OpenAI and Anthropic compatible. Same text as /agents.md. Beta. Some things may not work as described yet. ## Endpoints Base URL: https://api.sealedin.ai POST /v1/chat/completions OpenAI format Authorization: Bearer KEY POST /v1/messages Anthropic format x-api-key: KEY, anthropic-version: 2023-06-01 GET /v1/models model list GET /v1/catalog prices signed by the enclave GET /v1/quote TDX quote GET /v1/tls TLS endorsement ## Buying a key POST /v1/keys/buy with {"amount_usd": 20 to 100} answers 402 with an x402 `exact` challenge on Solana: USDC, treasury address, fee payer. Retry with the signed transaction in PAYMENT-SIGNATURE. The key is in the response after confirmation. The same request with an existing key as bearer tops it up. This spends the owner's money.

[How the GPU attestation is checked](/trust.md) > Beta. Some things may not work as described yet. # Contents declared. How SealedIn checks attested LLM inference: what we can see, what is verified, and what is not. ## Two checks. One endpoint. You talk to one endpoint. It is an enclave that checks other enclaves. An enclave is sealed hardware that can prove what code it runs. Your client checks the gateway (TDX quote and TLS endorsement). The gateway, in an Intel TDX enclave, checks each GPU enclave that runs a model (CPU and GPU attestation, key binding). 1. You check the gateway. GET /v1/quote returns an Intel-signed TDX quote that binds the enclave's key and measures its code. GET /v1/tls is that key's endorsement of the TLS certificate. Compare it with the certificate you are connected to: TLS ends inside the enclave, not at a proxy in front of it. 2. The gateway checks the GPUs. Before it uses a model instance, it verifies the CPU attestation, the GPU attestation and the key binding, then rechecks every 15 minutes and encrypts each request to that instance. This runs inside the code you measured in the first check. Your prompt is encrypted on the way and opened only inside those two enclaves. ## What we can see Spend and balance per key. That is what billing needs from us. Model, token counts and timing are recorded inside the enclave and no route exposes them, per request or per prompt. Our hosting provider sees your IP address and the size and timing of encrypted traffic. Payments are public on Solana. ## What is verified - [The source is open](https://github.com/sealedin): anyone can rebuild the image and compare its measurement with the one the enclave reports. - TLS terminates inside our Intel TDX enclave, and the enclave endorses the certificate. - The gateway has no administrative route reachable from outside, and its master key is derived inside the enclave. - The gateway checks the CPU attestation, the GPU attestation and the key binding of each upstream instance before using it, rechecks every 15 minutes, and encrypts each request to that instance. - Prices come from a catalog signed by the enclave. ## What cannot be verified - The check of the upstream cannot prove which weights ran, or what the upstream did with the prompt. ## Security model We rely on TEEs: Intel TDX for the gateway, GPU enclaves for the models. As long as they are not broken, your prompts and responses stay private. They are opened only inside those TEEs. The upstream today is Chutes. ## Out of scope Physical attacks on the hardware, side channels and compromise of the hardware vendors. > Beta. Some things may not work as described yet. # [SealedIn](/index.md) Conditions of carriage. - The service is provided as-is, during a test, with no uptime target and no warranty of any kind. - You are responsible for your prompts and for the content you generate. - The terms of the upstream provider, today Chutes, apply to you as well, including its indemnity for prompts and content. - Deposits are credits for inference on this endpoint and nothing else: they are not refundable, not withdrawable and not transferable. Credits never expire. - Per-key rate and spend caps apply, and we may freeze a key on abnormal spend. - We may end the test at any time; unused credits stay usable while the endpoint runs. > Beta.
