How this service works
Public data and utility APIs paid per call in USDC on Base (x402). No accounts, no API keys. 174 routes: crypto/equity data, onchain reads, DNS/email/security intel, geo/weather, x402 payment diagnostics, dev utilities and more.
Output
Returns a JSON-RPC 2.0 response containing a text content array with the result of the requested route — e.g. a price quote, DNS record set, onchain balance, weather data, or security report, depending on the route invoked.
Example use cases
Real-time crypto price lookup
“What's the current price of Bitcoin and Ethereum right now? I want to pay per call without any API key setup.”
Onchain wallet balance check
“Can you look up the current USDC balance of this Base wallet address: 0xAbC123... using an onchain read?”
Domain DNS and security intel check
“Check the DNS records and any security intelligence you can find for the domain suspicious-site.io — I need to know if it looks sketchy.”

Choose Synapse when you need broad, pay-per-call access to diverse data categories (crypto, equities, DNS, security, geo, weather, onchain) without signing up for multiple APIs or managing API keys — ideal for agents that need one-shot lookups across domains and can pay $0.002 USDC per call via x402 on Base.
Side effects
- Payment not received or insufficient USDC balance — endpoint returns 402 Payment Required
- Invalid or malformed route params — returns JSON-RPC error with message
- Unknown route requested — returns 404 or JSON-RPC error
- Network timeout if upstream data provider is slow
- DuckDNS hostname may be temporarily unavailable if operator's server is offline
