Verify API
Programmatic verification for payment binding, replay safety, outcome evidence and CommerceProof.
AUTONOMOUS COMMERCE ASSURANCE
Your payment succeeded. Did the service?
SafeGate proves what happened after payment.
A rail-agnostic commerce verification and evidence layer for AI agents, paid APIs, digital services and platforms. SafeGate binds payment to request, prevents replay, observes the actual outcome and produces portable CommerceProof.
Bind
Observe
Prove
ONE CORE. MULTIPLE SURFACES.
Use SafeGate where your commerce happens.
Developers, agents and platforms can use the same assurance model through different integration surfaces. Availability can evolve without changing the SafeGate core.
Middleware / Proxy
Place SafeGate inline with paid APIs and services so the actual request and response can become verifiable evidence.
SDK
Embed SafeGate verification and proof workflows directly into applications and platforms.
Agent / MCP
Give autonomous agents a machine-readable way to verify paid-service outcomes without giving SafeGate wallet authority.
CommerceProof
Portable signed evidence describing what was paid for, what happened and how strong the assurance is.
THE ASSURANCE PIPELINE
Payment movement is not the end of the commerce event.
SafeGate focuses on the missing layer between payment and a trustworthy machine-readable outcome.
Payment
→ Request binding
→ Durable single-consume / replay safety
→ Actual outcome observation
→ Evidence
→ Assurance
→ Signed CommerceProof
→ Optional public anchor
CLAIMED
Provider assertion only.
OBSERVED
SafeGate observed the paid request and actual outcome or equivalent execution evidence.
VALIDATED
Independent validator, TEE, zk, re-execution or another stronger validation method.
THIRD_PARTY_ATTESTED
An external trusted party contributes an attestation.
COMMERCE_VERIFIED
is emitted only when the configured assurance policy is actually satisfied.
A merchant claim alone is not enough.
RAIL-AGNOSTIC BY DESIGN
Payment rails can change. The assurance model stays the same.
SafeGate does not compete to move money. It sits above payment and execution environments to verify what actually happened.
Base Mainnet
Real USDC commerce verification proven.
Hedera x402
Real Testnet paid API flow, replay protection and anchored evidence proven.
Celo Mainnet
Real x402 USDC agent-commerce flow proven.
Circle / Arc
Arc Testnet end-to-end nanopayment assurance proven. Mainnet verification is next.
Pi Network
Historical Testnet work retained. Pi Network Mainnet completion remains on the roadmap.
SilentSwap Integration V1
COMPLETE
SilentSwap protects the route. SafeGate proves the outcome.
SafeGate integrates the current SilentSwap SDK order flow with request binding, replay-safe consumption, route evidence normalization and observed downstream commerce evidence.
SilentSwap OrderReference + OrderState → SafeGate binding → replay-safe consume → observed execution → Commerce Evidence
Route assurance: CLAIMED · Observed outcome assurance: OBSERVED
BUILT FOR PROGRAMMABLE COMMERCE
One assurance layer for developers, agents, platforms and commerce applications.
Developers
Integrate verification and CommerceProof through API and SDK surfaces.
AI Agents
Read deterministic assurance before trusting a paid API, dataset, inference or digital service.
Platforms
Embed SafeGate as middleware or an inline verifying proxy without becoming dependent on one payment rail.
Commerce Applications
Attach portable evidence to payment, delivery and digital-service outcomes.
CLEAR BOUNDARIES
SafeGate verifies commerce. It does not become the payment rail.
What SafeGate does
- Binds payment evidence to the intended request.
- Enforces durable single-consume and replay safety.
- Observes or validates outcomes at an explicit assurance level.
- Produces signed, portable commerce evidence.
What SafeGate is not
- Not a wallet, bank, exchange or payment processor.
- No custody, escrow or control of private keys.
- No autonomous authority to spend user funds.
- No claim of an official partnership where none exists.
