Registration alone is not a production-quality guarantee. |\n| Browser execution | Use the visible action or interactive controls. |\n| Browser processing | Server required |\n| HTTP API | /api/v1/tools/ip-lookup/run |\n| Browser-agent interface | run_current_tool |\n\n### Implementation notes\n\nUses the local diagnostic server to contact the supplied public host or DNS/RDAP provider. Only public internet addresses are permitted; requests time out and redirects are bounded.\n\n### Inputs and settings\n\nText input: IP address.\n\nExample or placeholder shown in the interface (not a validated fixture):\n\n```text\n8.8.8.8\n```\n\nUp to 1,000,000 characters. Review the settings before running.\n\nNo additional settings are declared for this tool.\n\n### HTTP contract\n\nAPI calls process supplied data on the server. The website origin is `https://happytails.ai`. Server API hosting is not connected on the public website yet. Use your local server origin to test these requests.\n\n```http\nPOST https://happytails.ai/api/v1/tools/ip-lookup/run\nContent-Type: application/json\n```\n\n[Detailed operation reference](https://happytails.ai/en/api/tools/ip-lookup.md) · [Shared API guide](https://happytails.ai/en/api.md)\n\n#### Limits\n\n| Limit | Value |\n| --- | --- |\n| request_bytes | 8388608 |\n| input_characters | 1000000 |\n| files_bytes | 5242880 |\n| max_files | 0 |\n| timeout_seconds | Operation-specific network bounds |\n\n#### Complete input schema\n\n```json\n{\n  \"type\": \"object\",\n  \"additionalProperties\": false,\n  \"properties\": {\n    \"input\": {\n      \"type\": \"string\",\n      \"maxLength\": 1000000,\n      \"default\": \"\",\n      \"description\": \"Plain text input.

Correct invalid input before retrying; retry server-busy responses with bounded backoff. Returned files contain Base64 data, not persistent download URLs. Decode and inspect the output before treating conversion as successful. See the shared API guide for the complete status and timeout rules.\n\n### Browser-agent workflow\n\n1. Open the human page in a browser that supports WebMCP.\n2. Discover the interface exposed by that page; use its actual schema.\n3. Select files on the page first when the tool requires files.\n4. Call `run_current_tool` with valid input and settings.\n5. Inspect the returned result or error and the displayed output. Retrieve files from the displayed download links.\n\nCalls do not automatically copy or download results. Browser permissions still apply. Interface availability alone is not proof of successful execution.\n\n### Planning specification\n\nASN, approximate geography and data timestamp; no street-address precision claim.\n\nThis describes intended requirements. Use the implementation notes, interface schema and observed output to determine current support.\n\n### Complete machine-readable capability record\n\n```json\n{\n  \"id\": \"ip-lookup\",\n  \"category\": \"network-tools\",\n  \"built\": true,\n  \"requirements\": \"ASN, approximate geography and data timestamp; no street-address precision claim.\",\n  \"implementation\": {\n    \"fields\": [],\n    \"processing\": \"Server required\",\n    \"note\": \"Uses the local diagnostic server to contact the supplied public host or DNS/RDAP provider.
