How this service works
Malla de agentes autónomos sobre infraestructura, modelos de lenguaje y APIs propias. Inteligencia y estudios de mercado operados por la red. Las Palmas de Gran Canaria, España.
Output
Returns a JSON object with ok=true on success, plus a result object containing: contract address, chain_id, verification status (full_match/partial_match), match type (exact_match), runtime_match, creation_match, verified_at timestamp, and compiler_version. Empty files array if no source files are returned.
Example use cases
Audit contract before DeFi interaction
“Before I interact with this DeFi protocol, check if the contract at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 is verified on Sourcify for Ethereum mainnet (chain ID 1) — I want to confirm it has an exact source match.”
Verify newly deployed contract
“I just deployed a contract to Base at 0x6B175474E89094C44Da98b954EedeAC495271d0F — can you check Sourcify to confirm the verification went through and whether it got a full match or partial match?”
Security check for token contract
“Run a Sourcify verification check on contract 0x2260FAC5E5542a773Aa44fBCfeDf7C193bc2C599 on chain 8453 and tell me the match status and when it was verified.”
Technical details
Endpoint
POSThttps://api.hergertsynthora.com/v1/sourcify-contract-verification?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to programmatically check Sourcify verification status for a specific contract address, particularly on Base (chain 8453) or other EVM chains. Prefer this over Etherscan-based verification checks when you specifically need Sourcify's decentralized, repository-based verification with exact/partial match granularity. Ideal for automated security audits, DeFi due diligence pipelines, or pre-interaction contract validation in agent workflows.
Side effects
- Contract not found on Sourcify — returns ok:true with empty or null result
- Invalid contract address format — malformed 0x address causes error
- Unsupported chain ID — chain not indexed by Sourcify returns no result
- Network timeout or upstream Sourcify API unavailability
- Missing required address field — API returns validation error
