Frequently Asked Questions
Common questions about Transfer Oracle, API pricing, model auditing, and compliance.
What is Transfer Oracle?
Transfer Oracle is an API that structurally audits ML model transformations — quantization, fine-tuning, pruning, distillation — and tells you whether your model still works before you deploy it. One API call, no model weights required.
How much does it cost?
Free tier: 1,000 credits/month (about 5 full audits). Pro: $49/month for 50,000 credits. Enterprise: $299/month for 500,000 credits. No credit card needed for the free tier.
How do I get an API key?
Go to the Account page, sign in, and click "Get My Free API Key". You'll get 1,000 credits immediately. Copy the key right away — it's shown only once.
How many credits does an audit cost?
A full structural audit (/v1/audit/transfer) costs about 200 credits. Real-time monitor checks (/v1/monitor/state) cost 1 credit each. You can check your balance anytime with GET /v1/account/credits.
What ML frameworks are supported?
Transfer Oracle is framework-agnostic — it works with any model that produces feature vectors. We have plugins for NVIDIA ModelOpt, NeMo, Triton, TensorRT, TAO, AMD Quark, AMD vLLM, and MLflow.
What does the audit certificate prove?
Each audit returns an HMAC-signed certificate containing the diagnosis, coverage score, timestamp, and input data hash. You can verify it via POST /v1/audit/verify-certificate. This proves the result is authentic and untampered — useful for compliance documentation.
Does Transfer Oracle help with EU AI Act compliance?
Yes. The audit output maps to EU AI Act Article 9 requirements for high-risk AI systems. The signed certificates provide documented evidence of model validation. Conformity assessments become mandatory August 2, 2026.
Do I need to share my model weights?
No. Transfer Oracle works on feature vectors (model activations), not model weights. You extract features locally and send only the numerical representations. Your model architecture and weights never leave your environment.
What's the difference between audit and monitor endpoints?
Audit (/v1/audit/transfer) does a full structural analysis comparing training and deployment data — use it before deploying. Monitor (/v1/monitor/state) checks individual inference vectors in real-time — use it in production to detect drift.
Can I cancel my subscription?
Yes, anytime. Your API key stays active until the end of your billing period. You can manage your subscription through the Stripe billing portal linked in your confirmation email.
Is there an SLA?
Pro tier includes email support (24-48 hours). Enterprise includes priority support. We're adding formal SLAs with the upcoming compliance-grade tier.
Are the plugins open source?
Yes. All 9 plugins are MPL-2.0 licensed on GitHub. You can use them commercially, modify them, and contribute back. The API itself is a commercial service.
