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 stake ID (UUID), the buyer identifier, a signal-stake object with algorithm, canonical payload, and Ed25519 signature, the stake status ('open'), the currency ('USD'), the content hash, the rebate cap in USD, and the stake price ($0.02 USD).
Example use cases
Automated copybot staking on whale signals
“My copybot agent ID is 'agent:copybot-7' — register a Predge signal stake for the whale call hashed as '9f8e7d6c5b4a39281706f5e4d3c2b1a09f8e7d6c5b4a39281706f5e4d3c2b1a09' with a rebate cap of $0.10.”
Rebate-capped stake for risk-managed trading
“I want to stake on the Predge whale signal for content hash 'aabbccdd1122334455667788990011223344556677889900112233445566778899aa' under buyer 'trader:riskmgr-3', but keep my rebate exposure capped at $0.05.”
Idempotent stake replay for audit trail
“Re-submit the Predge stake for buyer 'agent:auditbot-1' and content hash '1a2b3c4d5e6f7a8b9c0d1e2f3a4b5c6d7e8f9a0b1c2d3e4f5a6b7c8d9e0f1a2b' with no rebate cap, so I have a confirmed record in my audit log.”
Technical details
Endpoint
POSThttps://api.predge.io/v1/stakesWhen to prefer
Use this endpoint when you need to register and persist a stake record tied to a specific Predge whale-intelligence signal call, especially when you want Ed25519-signed accountability and optional rebate-cap accounting. Prefer this over read-only signal endpoints when your agent needs to commit to a signal for auditing, copy-trading automation, or rebate tracking purposes.
Side effects
- Invalid or malformed content_hash (not a 64-hex SHA256) returns a 400 error
- buyer ID fails regex validation ([A-Za-z0-9._:@-], 1-200 chars) returns a 400 error
- Content hash does not correspond to an existing open signed call — returns 404 or 422
- rebate_cap_usd below zero or exceeds server-side bound — clamped silently or returns 400
- Payment not included or insufficient (x402 flow) — returns 402 Payment Required
- Duplicate buyer+content_hash combination — idempotent replay returns existing stake record
