Questions, answered.
Do I need an account?
Not for the API: the wallet pays per request. For alerts, just the Telegram bot.
How do I verify a call?
Hit /verify?id=…, or recompute offline: sha256 the signed bytes, check it matches the content hash, verify the signature against our published key.
What chains and currency?
USDC over x402 on Base, Solana, Arc, Monad and Algorand.
Is this financial advice?
No. Predge is verifiable market intelligence, not advice. You decide what to do with it.
Can an AI agent use this without a human?
Yes, that's the whole point. x402 payments plus an MCP server mean an agent discovers, pays, and verifies on its own.
How is this different from other "whale trackers"?
The signature. Anyone can claim a call after the fact; we sign it before the outcome and let you check it.
How verification works
Published key
Our signing key is public at /.well-known/predge-keys.json. Every signature checks against it, offline.
Tamper-proof history
Calls are hash-chained; the chain head can be anchored to a public ledger, so even we can't rewrite the past.
