# Password Strength Analyzer API
[](https://password-strength.api.klymax402.com/mcp)
[](https://x402.org)
[](LICENSE)
Password strength analyzer with entropy calculation and crack time estimation. Pay-per-call via [x402](https://x402.org) (USDC on Base L2) -- no API key, no signup, no rate-limit wall.
Part of the [klymax402](https://klymax402.com) marketplace -- 100 x402 micropayment APIs for AI agents, one wallet, USDC on Base.
## Quickstart -- MCP
Add to your MCP client config (Claude Desktop, Cursor, ElizaOS, etc.):
```json
{
"mcpServers": {
"password-strength": {
"url": "https://password-strength.api.klymax402.com/mcp"
}
}
}
```
## Quickstart -- HTTP (x402)
```bash
curl -X POST "https://password-strength.api.klymax402.com/api/check" \
-H "Content-Type: application/json" \
-d '{"password":"..."}'
# -> 402 Payment Required, with an x402 payment challenge in the response body
```
Any x402-aware client ([`@x402/fetch`](https://www.npmjs.com/package/@x402/fetch), [`x402-agent-tools`](https://www.npmjs.com/package/x402-agent-tools), ATXP) handles the 402 -> sign -> retry cycle automatically.
## Tools
| Tool | Method | Path | Price | Description |
|---|---|---|---|---|
| `security_check_password` | POST | `/api/check` | $0.003 | Check password strength with entropy and crack time |
### `security_check_password`
Use this when you need to evaluate password strength or security. Returns a score 0-100, strength rating (weak/fair/strong/excellent), estimated crack time, entropy bits, and improvement suggestions. Checks against top 1000 common passwords. Do NOT use for hash generation — use crypto_generate_hash. Do NOT use for input validation — use data_validate_json.
**Parameters**
| Name | Type | Required | Description |
|---|---|---|---|
| `password` | string | yes | The password to analyze |
