THE PROBLEM
Machine payments fail silently.
When a payment flow is misconfigured, the request does not always crash. It simply stops settling. Settlens turns that uncertainty into evidence.
Settlement gaps
Verify that a successful response corresponds to a real, bound transaction.
Production blind spots
Catch replay, timeout and transport weaknesses in CI and controlled pilots.
ONE REPRODUCIBLE FLOW
From request to verified settlement.

EVIDENCE OVER ASSUMPTIONS
Independent by design.
Settlens never takes custody of funds or private keys. It produces deterministic checks and verifiable artifacts your engineers, partners and auditors can inspect.

FAQ
Questions, answered plainly.
What is x402?
x402 is an open protocol that lets clients pay for web resources over standard HTTP requests. Settlens tests implementations of that flow.
Do I need a token?
No. Settlens is not a blockchain and does not require a Settlens token.
Does Settlens custody funds?
No. Settlens is an assurance tool. It does not custody funds or request private keys.
Can I run it in CI/CD?
Yes. The CLI, GitHub Action and JSON/SARIF reports are designed for automated checks.
