## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability fastx402-env-file-parser-9f2c8b65
```

Example prompt: Can you parse this .env file content for me and give me all the environment variables as a structured list: 'DB_HOST=localhost\nDB_PORT=5432\nDB_NAME=my_database\nEMPTY='

## When to prefer this

Choose this endpoint when you need to programmatically parse raw .env file text into a structured key-value object without setting up any account or API key. Ideal for agents that need to inspect, migrate, or validate environment configuration files on the fly at minimal cost ($0.001 USDC per call).

## Known failure modes

- Missing 'content' query parameter returns an error
- Malformed .env content with syntax errors may result in partial parsing or an error
- Very large .env files may hit size limits
- Non-.env formatted input (e.g. YAML, JSON) may produce unexpected results or empty output

## How this service works

200 pay-per-call tools for AI agents, from $0.001 per request in USDC on Base or Solana with x402. No account, no API key.

## Output

A JSON object with a 'variables' key containing a flat key-value map of all environment variable names and their string values, including empty-valued variables. Example: {"variables": {"DB_HOST": "localhost", "DB_PORT": "5432", "EMPTY": ""}}
