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
Returns a JSON object that structurally mirrors the input XML, with XML elements mapped to JSON keys, attributes preserved (prefixed with @_), and nested elements represented as nested objects. The response wraps the parsed data under a 'data' key.
Example use cases
Parse RSS feed XML response
“I got an RSS feed response as XML and need it as JSON so I can process the items — here's the XML: '<rss version="2.0"><channel><title>Tech News</title><item><title>AI Update</title><link>https://example.com/ai</link></item></channel></rss>'”
Convert SOAP API XML to JSON
“This legacy SOAP service returned XML and I need it in JSON format to pass to my next pipeline step — can you convert it? '<response><status>ok</status><data><id>42</id><name>Widget</name></data></response>'”
Transform config file format
“I have this XML config file and need it converted to JSON so I can use it in my Node.js app: '<config><database><host>localhost</host><port>5432</port></database><debug>true</debug></config>'”
Technical details
Endpoint
GEThttps://fastx402.tools/xml-to-json?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, no-setup, pay-per-call XML-to-JSON conversion without managing API keys or accounts. Ideal for one-off conversions in agent pipelines, processing RSS/Atom feeds, parsing SOAP responses, or transforming config files, especially when you want to pay per use in USDC on Base or Solana via x402 rather than maintaining a subscription.
Side effects
- Malformed or invalid XML input returns an error — the xml query parameter must be well-formed XML
- Missing xml query parameter results in a 400-level error
- Very large XML payloads may be truncated or rejected
- XML with namespaces or special characters may not parse as expected
