How this service works
Real-time alerts on whale traders on Polymarket. Heuristic Insider Watch, wallet scoring 0–100, Bloomberg-style web terminal. Free plan included.
Output
Returns a JSON object containing a unique call ID (UUID), a sequence number, a signed call object with ed25519 algorithm and canonical payload, and two SHA hashes (prev_hash and content_hash) forming a tamper-evident chain of prediction records.
Example use cases
Auditable whale call on hot market
“Record a 'yes' position call on Polymarket condition 0xdef456 with a $500 stake and note 'whale wallet cluster accumulating' on Predge — I want a signed, chained proof of my call.”
No-side prediction with research note
“Log a 'no' call on Polymarket condition 0x7890ab with no stake but add the note 'heuristic insider score spiked bearish' so I can track my analysis on Predge.”
Tracking a small speculative call
“Submit a signed 'yes' call on Predge for Polymarket condition 0x112233 with a $25 stake — no note needed, just create the record so my call history is on-chain verifiable.”
Technical details
Endpoint
POSThttps://api.predge.io/v1/callsWhen to prefer
Choose this endpoint when you need a cryptographically signed, tamper-evident, sequentially chained log of a Polymarket prediction call — especially for whale-grade accountability, auditability, or building a verifiable track record of positions on open Polymarket markets. Prefer it over simple off-chain note-taking when provable timestamps and ed25519-signed integrity matter.
Side effects
- Invalid or closed Polymarket condition_id returns an error (market not open)
- Malformed side value (not 'yes' or 'no') causes validation failure
- Note exceeding 500 characters is rejected
- Invalid size_usd format (not fixed 2 decimal places) causes rejection
- Payment failure (insufficient USDC) blocks the call from being recorded
- Signature verification failure returns authentication error
