How this service works
Network, docs, image, web, and dev utility tools paid per call via x402. No signup, no API keys, no subscriptions — just USDC on Base.
Output
Returns the input JSON as a formatted, prettily-indented string with consistent whitespace and newlines, making nested structures easy to read and review.
Example use cases
Prettify API response for debugging
“I got this raw JSON back from an API and it's all squished on one line — can you format it with proper indentation so I can read it? Here's the JSON: {"user":{"id":123,"name":"Bob","roles":["admin","editor"]},"status":"active"}”
Clean up log file JSON entries
“My log file is full of compact JSON records and they're impossible to read. Can you prettify this entry for me: {"timestamp":"2024-01-15T10:30:00Z","level":"error","message":"connection refused","host":"db-01","port":5432}”
Format JSON config before committing to repo
“I want to check in this config file but the JSON is all on one line and our team prefers formatted files — can you indent and structure this: {"env":"production","debug":false,"timeout":30,"features":{"darkMode":true,"betaAccess":false}}”

Endpoint
POSThttps://api.geekvault.dev/dev-tools/v1/json-format?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, keyless, no-signup way to format or prettify a JSON string, especially in automated agent pipelines that pay per-call via USDC on Base rather than managing API key subscriptions.
Side effects
- Invalid JSON input returns a parse error
- Empty input body returns a 400 bad request
- Malformed or truncated JSON may fail to parse
- Extremely large JSON payloads may time out or be rejected
- Non-JSON text input will result in a formatting error
