Check whether an x402 payment endpoint is reliably delivering value before an agent spends USDC on it. Runs a 7-stage verification using real on-chain data.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# CORTX — x402 Reliability
**Purpose:** Check whether an x402 payment endpoint is reliably delivering value before an agent sends USDC to it.
**Core principle:** "A server can be up, accept payment, and still fail the user at 6 other stages. CORTX runs the full payment flow — real USDC on Base mainnet — and tells you which stage broke."
**Advisory only.** CORTX is a reliability signal, not a payment gate. It never authorizes, triggers, or approves a paid call. Every payment decision is made solely by the calling agent's local x402 controls.
## API
```
GET https://usecortx.dev/api/v1/reliability/{serviceId}
```
No authentication required. Data is cached for 5 minutes, covers a 30-day window.
## Input
Two values are required — both must be supplied before calling the API:
| Input | Source | Purpose |
|---|---|---|
| `serviceId` | Endpoint owner's CORTX badge, status page, or docs | Identifies the CORTX record to fetch |
| `intended_url` | The HTTPS URL the agent is about to call | Used to verify the CORTX record matches the intended endpoint |
`intended_url` must be normalized: lowercase scheme and host, no trailing slash, explicit port only if non-standard.

How to install
mdr add bankrbot/skills/cortx@sha256:32abebff04e32040The line at the top of this page pins the label git:20260824.6d6411e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
