Terms of Service
Effective date: June 26, 2026
These terms govern your use of the block0 website and API (the “Service”). By using the Service, you agree to them. If you don’t, please don’t use it.
1. The Service
block0 returns read-only intelligence derived from public onchain data, over HTTP and MCP. There are no accounts or API keys — each request is paid for on its own. We may change, add, or remove endpoints and apply rate limits at any time.
2. Payments
Paid endpoints are settled per request in USDC over x402. The price is shown in the 402 response and in our catalog. You pay network fees and control the wallet that signs. Onchain payments are final and non-refundable except where the law requires otherwise. We never hold your keys or your funds.
3. Acceptable Use
Don’t use the Service to break the law, to get around payment or rate limits, to attack or overload our systems, or to enable fraud or market manipulation.
4. No Financial Advice
Scores and signals are informational only and may be incomplete or delayed. They are not financial, investment, legal, or tax advice. Decisions you make using them are your own.
5. Disclaimer & Liability
The Service is provided “as is,” without warranties of any kind. We don’t guarantee it will be uninterrupted, accurate, or error-free. To the fullest extent allowed by law, block0 is not liable for any indirect or consequential damages, or for lost profits, data, or trading losses.
6. Changes & Contact
We may update these terms; changes take effect when the date above changes, and continued use means you accept them. Questions? [email protected].
