Keyless, wrong key, wrong module, wrong chain — all **HTTP 200**, `Content-Type: application/json`, body `{\"status\":\"0\",\"message\":\"NOTOK\",\"result\":\"<reason string>\"}`. `status` is a **string** (`\"0\"`/`\"1\"`), and `result` — normally the data — carries the error text. Read `status`, not the HTTP code.\n\n## V1 (`/api`) answers only one thing now\n\n```\ncurl \"https://api.etherscan.io/api?module=proxy&action=eth_blockNumber\"\ncurl \"https://api.etherscan.io/api?module=proxy&action=eth_blockNumber&apikey=<placeholder>\"\ncurl \"https://api.etherscan.io/api?module=bogus&action=eth_blockNumber\"\ncurl \"https://api.etherscan.io/api\"\n```\n\nAll four → `{\"status\":\"0\",\"message\":\"NOTOK\",\"result\":\"You are using a deprecated V1 endpoint, switch to Etherscan API V2 using https://docs.etherscan.io/v2-migration\"}` (HTTP 200, 155 bytes). The key, module and action are not even looked at. A memorized V1 URL \"works\" (200) and returns no data.\n\n## V2 (`/v2/api`) validation order: chainid, then apikey, then everything else\n\n```\ncurl \"https://api.etherscan.io/v2/api?module=proxy&action=eth_blockNumber\"\n  -> result: \"Missing chainid parameter (required for v2 api), please see https://api.etherscan.io/v2/chainlist for the list of supported chainids\"\ncurl \"https://api.etherscan.io/v2/api?chainid=99999999&module=proxy&action=eth_blockNumber\"\n  -> result: \"Missing or unsupported chainid parameter (required for v2 api), please see …/v2/chainlist …\"\ncurl \"https://api.etherscan.io/v2/api?chainid=1&module=proxy&action=eth_blockNumber\"\n  -> result: \"Missing/Invalid API Key\"\ncurl \"https://api.etherscan.io/v2/api?chainid=1&module=proxy&action=eth_blockNumber&apikey=<placeholder>\"\n  -> result: \"Invalid API Key (#err2)\"\ncurl \"https://api.etherscan.io/v2/api?chainid=1&module=bogus&action=nope\"\n  -> result: \"Missing/Invalid API Key\"      (module/action not validated before the key)\ncurl \"https://api.etherscan.io/v2/api\"\n  -> result: \"Missing chainid parameter …\"\n```\n\nMissing key and invalid key are distinguishable (`Missing/Invalid API Key` vs `Invalid API Key (#err2)`).
