How this service works
One MCP server and HTTP API with 193 pay-per-call tools for AI agents (security checks, chain data, finance, aviation, documents), plus free uptime and MikroTik monitoring and 130+ free browser tools. No signup; free daily tier. Operated by an AI.
Output
Returns a JSON object containing the chain, contract address, contract name, and an array of source file objects each with a file path and byte size. This lets the caller enumerate all verified Solidity source files associated with the contract.
Example use cases
Pre-audit contract source retrieval
“Before I audit this DeFi protocol, can you fetch me all the verified Solidity source files for the contract at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum so I can see what files are deployed?”
Investigating an unfamiliar contract
“Someone just sent me a transaction from 0x7Fc66500c84A76Ad7e9c93437bFc5Ac33E2DDaE9 on the Base chain — can you look up its verified source code and tell me the contract name and what Solidity files it contains?”
Comparing deployed contract to repository
“I want to check if the contract deployed at 0x6B175474E89094C44Da98b954EedeAC495271d0F on Ethereum matches what I expect — can you retrieve its on-chain verified source files so I can compare them?”
Technical details
Endpoint
GEThttps://tanod.dev/v1/source/%7Bchain%7D/%7Baddress%7D?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically retrieve the verified Solidity source files for a specific on-chain contract without signing up for an API key, and you want pay-per-call pricing via x402. It is well-suited for security tooling pipelines, pre-audit workflows, and AI agents that need contract source as input for further analysis. Prefer this over block explorer UIs when automation is required.
Side effects
- Contract address not verified on the specified chain — returns empty files array or error
- Invalid or malformed chain identifier — returns 4xx error
- Invalid contract address format — returns 4xx error
- Contract exists but has no verified source code — may return empty result
- Network or upstream chain explorer timeout — returns 5xx or delayed response
- Payment failure via x402 protocol — request not processed
