Get Attestation Report

Returns cryptographic proof of TEE execution with hardware-signed measurements. 
GET https://api.redpill.ai/v1/attestation/report?model={model_id}&nonce={nonce}&signing_address={address}
Try it now! Click the “Try it” button above to test the API in the playground. You’ll need:
  1. Your API key (add it when prompted)
  2. The model parameter is pre-filled with phala/qwen-2.5-7b-instruct
  3. Optionally add nonce for replay protection
Security Best Practice: Always include a fresh random nonce when fetching attestations to prevent replay attacks. Generate a 32-byte random value (64 hex characters) for each request.

​
Parameters

​
model
string
default:"phala/qwen-2.5-7b-instruct"
Model ID for TEE attestation (required for Phala confidential models)Examples: phala/qwen-2.5-7b-instruct, phala/deepseek-chat-v3-0324, phala/gpt-oss-120b
​
nonce
string
Random 32-byte value (64 hex characters) to prevent replay attacks. The nonce will be embedded in the TEE attestation report data.Example: a1b2c3d4e5f6... (64 hex characters)Security: Generate fresh nonce for each request using secrets.token_hex(32) in Python or openssl rand -hex 32 in bash.
​
signing_address
string
Ethereum address (ECDSA) or Ed25519 public key to filter attestations in multi-server deployments.Use case: When verifying signatures, provide the signing address recovered from the signature to get attestation for that specific TEE instance.Example: 0x1234567890abcdef... (ECDSA address)

​
Example

​
Basic Request (without nonce)

curl "https://api.redpill.ai/v1/attestation/report?model=phala/qwen-2.5-7b-instruct" \
  -H "Authorization: Bearer YOUR_API_KEY"

# Generate fresh nonce
NONCE=$(openssl rand -hex 32)

curl "https://api.redpill.ai/v1/attestation/report?model=phala/qwen-2.5-7b-instruct&nonce=$NONCE" \
  -H "Authorization: Bearer YOUR_API_KEY"

​
With Signing Address (for signature verification)

NONCE=$(openssl rand -hex 32)
SIGNING_ADDRESS="0x1234567890abcdef..."

curl "https://api.redpill.ai/v1/attestation/report?model=phala/qwen-2.5-7b-instruct&nonce=$NONCE&signing_address=$SIGNING_ADDRESS" \
  -H "Authorization: Bearer YOUR_API_KEY"
