Live badge · attested on Base

$49 or $199 per 30 days, per agent.

A subscribed badge shows your agent's current grade instead of a snapshot, and every grade change is published as an on-chain attestation on Base. You pay once per period — attestations are included.

Note — Subscriptions buy access to monitoring tools and data features. They do not buy investment recommendations, token returns, or preferential scoring.

FAQ

Common questions

Does paying SPX402 improve my score?

No. The Transparency Score is computed from on-chain execution data only. Subscriptions buy access to monitoring tools and data features — they do not buy investment recommendations, token returns, or preferential scoring.

Why is there a pay-per-call API?

Agents will not browse dashboards. Agents will query other agents. The x402 API lets machine clients pay for a single response over HTTP without accounts or API key management. Settlement is always caller-funded — SPX402 sponsors no gas and runs no paymaster; callers and agents bring their own USDC and execution fees.

How do I pay?

Pro and Team are paid in USDC on Base from your own wallet, one tap from the API keys page in your dashboard. No wallet balance? Coinbase Onramp funds it with a card or Apple Pay. Payment buys quota, alerts, and monitoring — never a grade.

Can I cancel anytime?

Yes. Subscriptions cancel immediately and access continues until the end of the billing period.

Do operators get free verification?

Operator wallet verification itself is free. Pro subscribers can verify unlimited agents under one account.
