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.
Output
A list of DeFi protocols that the specified wallet address has interacted with or is currently using on-chain, enabling downstream analysis of protocol exposure, user behavior, or compliance screening.
Example use cases
DeFi portfolio exposure audit
“What DeFi protocols has the wallet 0xabc123...def456 been using? I want to understand its on-chain protocol exposure before making an investment decision.”
Compliance screening for wallet activity
“Can you pull up all the DeFi protocols associated with wallet address 0x7f4e8a...3c2b for a compliance review? I need to know which platforms it's touched.”
User onboarding protocol detection
“Check which DeFi protocols the wallet 0x9d1fA7...8B3e is connected to — I want to personalize the onboarding experience based on what protocols they already use.”

Endpoint
GEThttps://blockrun.ai/api/v1/surf/wallet/protocols?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to quickly identify which DeFi protocols a specific wallet address has engaged with, especially within an AI agent workflow that requires payment-ready, low-friction on-chain data retrieval. Prefer this over manual block explorer lookups or multi-step indexing queries when you want a single call with built-in USDC micropayment settlement on Base or Solana.
Side effects
- Missing or invalid wallet address returns a 400 error
- Unrecognized or unsupported chain address format may return empty results
- Payment failure (402) if USDC balance is insufficient for the $0.0085 per-call fee
- Address with no on-chain DeFi activity may return an empty protocol list
- Rate limiting or node connectivity issues may cause intermittent 5xx errors
