x402 reliability infrastructure

Your x402 service can be
online and still be broken.

CORTX makes controlled paid test calls and verifies payment terms, settlement, delivery and response schema — so you catch failures before users do, on a schedule you control.

The problem

A successful HTTP response is not successful service delivery.

Your server can respond while the payment flow, returned JSON or expected schema is broken. Traditional monitoring does not check any of this.

How it works

CORTX tests the service like a real customer.

Using a safe payload, dedicated testing wallet and strict spending limit, CORTX runs the complete paid request and records evidence at every stage.

01
Configure
Add your endpoint, a safe test payload, expected price range, and the JSON Schema for a valid response.
02
Pay
CORTX performs a real EIP-3009 USDC authorization from a dedicated synthetic wallet on Base mainnet, within your defined price cap.
03
Verify
Every stage is checked independently — payment terms, price, settlement, delivery, JSON validity, and schema conformance.
04
Alert
On repeated failure, CORTX opens an incident and notifies you via Telegram before your users notice.
Evidence

Stop guessing where the request failed.

See the exact payment terms, response body, schema errors and stage timings behind every incident. Evidence stored for every check run.

Safety

Real payments, controlled exposure.

Set the maximum price, test frequency and monthly budget. CORTX blocks calls when quoted terms exceed your policy.

Builder-defined price cap
CORTX blocks any call where the quoted price exceeds your maximum.
Dedicated synthetic wallet
Tests run from an isolated wallet, separate from any production funds.
Configurable interval
Choose how frequently CORTX tests your service, balancing cost and coverage.
Monthly spend cap
Set an absolute USDC budget for the month. Checks pause when it's reached.
Auto-blocked on price change
If quoted price changes unexpectedly, the call is blocked and an alert fires.
Public status pages & badge

Turn reliability into proof partners can see.

Every service gets a public status page showing 90-day uptime, paid delivery success, schema validity, and median latency — updated live after every check. Embed the CORTX Monitored badge anywhere.
