Export KitScreen any agent payment before it executes. One POST, one response. Three possible verdicts:
Verigate scores risk, checks sanctions, detects prompt injection, evaluates behavioral anomalies, and returns a signed receipt. On uncertain cases (STEP_UP), it autonomously purchases independent evidence before deciding.
Every decision produces an Ed25519-signed, hash-linked receipt anchored to BASE mainnet.

Authentication
Verigate is currently in open beta. No API key required. All endpoints accept unauthenticated requests.
Payment is per-call via USDC on Base. The screening fee ($0.05) is collected either upstream via x402 Gateway nanopayments or via direct wallet transfer.
# Step 1: Call endpoint — get 402 + payment requirements curl https://verigate.cloud/x402/security-check # Step 2: Pay via Circle Gateway (gas-free) circle services pay \ https://verigate.cloud/x402/security-check \ --address 0xYOUR_WALLET \ --chain BASE-SEPOLIA # Step 3: Endpoint returns security verdict
Screen Payment
Submit a payment intent for risk assessment. Returns a verdict, risk breakdown, enforcement state, and signed receipt.

Response Types
Six possible response shapes depending on the verdict and enforcement state.
| Type | What triggers it | Key fields | Cost |
|---|---|---|---|
| APPROVE | Low risk, no uncertainty | decision + risk + receipt | $0.05 |
| STEP_UP → APPROVE | Uncertain, evidence confirmed safe | + step_up.validator_verdict + gemini_reasoning | $0.07 |
| STEP_UP → DENY | Uncertain, evidence confirmed dangerous | + governance + settlement proof | $0.07 |
| DENY | High risk, unambiguous | + governance intel + receipt | $0.05 |
| REPLAY | Same denied intent re-submitted | replay: true + enforcement | $0.00 |
| BREAKER | 5 denials → throttle, 10 → suspend | enforcement.status: SUSPENDED | $0.00 |
Event-driven agent endpoint. Submit a payment event and Verigate evaluates economic rationality: is the evidence worth buying?
Returns economic rationality stats at GET /api/agent/stats
curl -X POST https://verigate.cloud/api/agent/handle \ -H "Content-Type: application/json" \ -d '{ "payee": "0x742d35Cc...", "amount": "0.50", "service": "price-feed" }'
Natural language to Circle wallet policy. Describe what you want in plain English, Gemini generates a structured Circle-compatible policy.
curl -X POST https://verigate.cloud/api/synthesize-policy \ -H "Content-Type: application/json" \ -d '{ "description": "Allow up to $10 per tx, max 5 tx per hour, only to known vendors on the allowlist" }'
Cross-agent scope negotiation. Two agents propose their policies, Gemini negotiates a mutually acceptable scope.
curl -X POST https://verigate.cloud/api/negotiate-scope \ -H "Content-Type: application/json" \ -d '{ "agent_a_policy": "Max $5/tx, data APIs only", "agent_b_policy": "Max $20/tx, any service" }'
x402-paid proof pull. Carrier agents pay $0.25 USDC for the full signed evidence bundle. Requires a valid consent grant and payment proof.
curl -X POST https://verigate.cloud/api/carrier/pull \ -H "Content-Type: application/json" \ -d '{ "carrier_id": "carrier-agent-1", "bundle_ref": "bundle_abc123", "tx_hash": "0xdfcd6729a28fe...", "purpose": "underwriting" }'

Python SDK
Drop-in screening for any Python agent. Works with LangChain, CrewAI, OpenAI function calling, or plain Python.
from verigate import screen result = screen({ "from": "procurement-agent", "to": "0x742d35Cc6634C053...", "amount": 500, "currency": "USDC", "purpose": "SaaS subscription renewal" }) if result["verdict"] == "APPROVE": execute_payment() elif result["verdict"] == "STEP_UP": # Verigate is buying evidence — wait wait_for_confirmation() else: log_blocked(result["reasoning"])
Framework Integrations
Plug Verigate into your existing agent framework with one import.
from verigate.integrations import VerigateToolkit toolkit = VerigateToolkit( base_url="https://verigate.cloud" ) agent = initialize_agent( tools=toolkit.get_tools(), llm=llm )
from verigate.integrations import VerigateCrewTool screen_tool = VerigateCrewTool( base_url="https://verigate.cloud" ) agent = Agent( role="Purchasing Agent", tools=[screen_tool] )
from verigate.integrations import verigate_openai_schema response = openai.chat.completions.create( model="gpt-4", tools=[verigate_openai_schema()], messages=messages )
from verigate import screen def x402_middleware(payment): v = screen(payment) if v["verdict"] != "APPROVE": raise BlockedPayment(v) return route(payment)
MCP Server
Connect Claude Desktop, Cursor, or any MCP-compatible client directly to Verigate. Tools available:
// claude_desktop_config.json { "mcpServers": { "verigate": { "command": "npx", "args": [ "mcp-remote", "https://verigate.cloud/mcp" ] } } }
# Run as standalone MCP server (stdio) python -m verigate.mcp_server
Three Products, Three Prices
Every piece of intelligence Verigate produces is a product someone pays for. Pay per use via USDC. No monthly minimums.
Decision + risk score + forensic summary + recommendation change types.
Everything in Screening, plus full forensic analysis and actionable recommendations with rationale.
Full signed proof bundle for carrier underwriting. Paid via x402 Gateway nanopayments.
How Payment Works
Call POST /api/check with tier: "screening" or tier: "governance". Fee is collected via x402 Gateway nanopayments (gas-free, sub-cent USDC) or direct wallet transfer.
Call POST /api/carrier/pull with a tx_hash proving $0.25 USDC payment. Requires a valid consent grant. Returns the full signed evidence bundle.
All payments settle in USDC on Base mainnet via Circle Agent Wallets. No gas fees. No monthly minimums. No signup. Pay per use.
Volume Pricing
| Tier | Screening | Governance | Evidence | Target |
|---|---|---|---|---|
| Standard | $0.05 | $0.15 | $0.25/pull | Individual agents, dev testing |
| Volume | $0.02 | $0.08 | $0.25/pull | >1,000 checks/day, API contract |
| Enterprise | Custom | Custom | Per-insured/period | Carrier-integrated, SLA-backed |
Verigate lets an agent pay a small, policy-limited USDC amount for evidence before deciding whether to release a larger, risky payment. Gemini helps interpret the evidence, deterministic controls make the decision, and Circle settles it.
