How this service works
BlockRun lets AI agents use money well: pay for results, not for seats or subscriptions, and put every cent on the model or tool that actually does the job.

Example use cases

“Find me wallets on Polymarket that trade similarly to 0xAbCd1234...5678 — I want to follow traders who bet like this one.”
Competitor analysis for prediction markets
“Which Polymarket wallets have similar trading behavior to 0xDEAD...BEEF? I'm trying to understand who the comparable players are in these markets.”

Endpoint
GEThttps://blockrun.ai/api/v1/pm/polymarket/wallet/0x0000000000000000000000000000000000000000/similar?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to discover Polymarket traders with behavioral similarity to a known wallet — ideal for building trader networks, identifying copy-trade candidates, or performing competitive analysis within prediction markets. Prefer this over general wallet lookup endpoints when the goal is similarity-based discovery rather than direct wallet data retrieval.
Side effects
- Invalid or malformed wallet address returns an error or empty result
- Zero address (0x000...000) may return no meaningful similar wallets
- Wallet with no Polymarket activity may yield empty results
- Payment failure (402) if USDC balance is insufficient
- Rate limiting or upstream Polymarket API unavailability
