Important differences between the deprecated legacy API and the new APIv2: - **Ticketing**: The verfication requests resolve into tickets/verification jobs. - Previously the verification happened during the HTTP request, which resulted in timeouts if compilation took longer - **Standard JSON as default**: In the current design we take the standard JSON format as our main verification endpoint. Other methods such as "multi-file" or "single-file" should be handled by frontends or tooling to format into std-json. We still support verification with metadata at `/v2/verify/metadata`. - **Lean API**: We keep the number of endpoints minimal compared to v1. We won't have a session API. - **Detailed contract response**: Prev. we only returned contract files of a contract. Now we can return details at `/contract/{chainId}/{address}`. By submitting source code for verification, you grant Sourcify (and the Argot Collective) a non-exclusive, worldwide, irrevocable, royalty-free licence to reproduce, store, and publicly display the submitted source code for the purposes of verification, archival, and public inspection. license: name: MIT url: https://github.com/argotorg/sourcify/blob/master/LICENSE contact: name: Sourcify url: https://sourcify.dev email: hello@sourcify.dev servers: - url: https://sourcify.dev/server description: Production server security: [] tags: - name: Contract Lookup description: API v2 - Tools and endpoints for looking up contract information - name: Verify Contracts description: API v2 - Submit a contract for verification - name: Verification Jobs description: API v2 - Check the status of a verification job - name: Other description: General server endpoints paths: /v2/verify/etherscan/{chainId}/{address}: post: tags: - Verify Contracts summary: Import from Etherscan description: >- Import a contract verified on an Etherscan instance or a service with Etherscan-alike API operationId: import-from-etherscan parameters: - name: chainId in: path description: The chainId number of the EVM chain required: true schema: type: string pattern: ^\d+$ minLength: 1 maxLength: 20 example: '11155111' - name: address in: path description: >- Contract's 20 byte address in hex string with the 0x prefix.
