Forge Verify SDK — Verify AI agent decisions with cryptographic attestation

forge-verify

Forge Verify SDK for Python. Verify AI agent decisions with cryptographic attestation.

Install

pip install forge-verify

Quick Start

from forge_verify import ForgeVerify

forge = ForgeVerify(api_key="vt_live_...")

result = await forge.verify_decision(
    agent_id="agent-1",
    action="payment.create",
    params={"amount": 100, "currency": "USD"},
    policy="finance-controls",
)

if result.verified:
    # Action approved
    pass
else:
    print("Blocked:", result.reason)

Synchronous Usage

from forge_verify import ForgeVerify

forge = ForgeVerify(api_key="vt_live_...")
result = forge.verify_sync("send_email", params={"to": "[e-mail]"}, policy="email-controls")

verify_sync() works in plain scripts, running asyncio event loops, FastAPI contexts, and Jupyter notebooks.

API

ForgeVerify(api_key, **options)

Option	Type	Default	Description
api_key	str	required	API key (vt_live_..., vt_sandbox_...)
base_url	str	https://veritera.ai	API base URL
timeout	float	10.0	Request timeout (seconds)
max_retries	int	2	Retries on 5xx errors
fail_closed	bool	True	Return denied instead of raising on errors
debug	bool	False	Enable debug logging

Aliases: Forge, Veritera (backward compatibility)

Methods

• verify_decision(agent_id, action, ...) — Verify an agent action against policy
• get_proof(proof_id) — Retrieve a verification proof
• verify_proof_locally(attestation, payload, public_key) — Verify attestation offline (Ed25519)
• create_delegation(agent_id, allowed_actions, ...) — Create a scoped agent delegation
• get_usage(period=None) — Get billing usage stats
• health() — Check API health

Error Handling

from forge_verify import ForgeError, RateLimitError

try:
    result = await forge.verify_decision(...)
except RateLimitError as e:
    # Wait e.retry_after_ms before retrying
    pass
except ForgeError as e:
    print(e.code, e.status, str(e))

Fail-Closed (Default)

When fail_closed=True (default), network/server errors return a denied result instead of raising. The agent is blocked, not crashed.

Circuit Breaker

After 5 consecutive failures, the SDK opens a circuit breaker for 30 seconds. After 30s, one request is allowed through (half-open). On success, the circuit closes.

Idempotency

Pass idempotency_key to verify_decision() to prevent duplicate processing:

result = await forge.verify_decision(
    agent_id="agent-1",
    action="payment.create",
    idempotency_key="unique-request-id",
)

Migrating from veritera

pip uninstall veritera
pip install forge-verify

Update imports:

# Before
from veritera import Veritera
# After (Veritera still works as alias)
from forge_verify import ForgeVerify

Requirements

• Python >= 3.9
• Dependencies: httpx, cryptography
