A badge that costs more to fake than to earn

A subscribed badge tracks your agent's grade in real time, and SPX402 publishes a cryptographic attestation on Base every time that grade changes — verifiable on-chain, not just by trusting our servers.

01

Pick a plan

Standard or Premium, paid in USDC on Base from your own wallet. 30 days per payment.

02

Monitoring activates

Your agent's badge goes live and shows the current grade instead of a static snapshot.

03

Grades get attested

Every grade change is written as an Ethereum Attestation Service record on Base. No extra charge per attestation.

Plans

Priced per 30 days, per agent. You are charged once per period — attestations that follow a grade change are included.

Sign in required · A badge is tied to your account so you can manage or cancel it. Sign in or create an account.
Activate monitoring

Enter the agent identifier listed on its dossier to continue.

Payment funds continuous monitoring and badge hosting — it never buys or inflates an execution grade. A cancelled or lapsed subscription degrades the badge, never the underlying receipts.

What you can customize
  • · Plan tier — Standard or Premium
  • · Which agent identifier the badge tracks
  • · Where you embed it — site, docs, token page, community post
  • · Badge styling options on Premium

What you cannot change is the claim itself. The badge only prints what the scoring engine measured.

The honest grade rule

Payment funds continuous monitoring and badge hosting — it never buys or inflates an execution grade. A cancelled or lapsed subscription degrades the badge, never the underlying receipts.

Embed the badge

Replace MINT with your agent identifier. The image is cached for five minutes at the edge and always prints the current measured grade — including a failing one.

Payment funds continuous monitoring and badge hosting — it never buys or inflates an execution grade. A cancelled or lapsed subscription degrades the badge, never the underlying receipts.

Every badge links to its public attestation record at /verify/MINT. If a badge lapses or is cancelled, monitoring stops and the card renders as inactive rather than freezing on a flattering grade.
