How this service works

Obol sells verified blockchain data over x402, settled in USDC on Base.

Output

Returns a structured object indicating whether the queried blockchain address appears on any sanctions lists, along with relevant compliance flags or risk indicators derived from verified on-chain data.

Example use cases

Pre-transaction compliance check

“Before I send USDC to wallet 0xabc123...def456, can you run a sanctions check on it to make sure it's not blacklisted or OFAC-flagged?”

DeFi protocol counterparty screening

“I need to screen the address 0x9f8e7d6c5b4a3f2e1d0c9b8a7f6e5d4c3b2a1f0e for sanctions before we allow it to interact with our liquidity pool — can you check it?”

Crypto exchange onboarding KYC

“We're onboarding a new user whose deposit wallet is 0x3a4b5c6d7e8f9a0b1c2d3e4f5a6b7c8d9e0f1a2b — run a sanctions screening on that address and tell me if there are any red flags.”
