How this service works
Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.
Output
Returns a JSON object with a boolean `found` field indicating whether the pointer resolved successfully, and a `value` field containing the extracted data at that path (e.g. {"found": true, "value": "Ana"}).
Example use cases
Extract nested config value
“I have a big config JSON blob and I need to pull out just the value at /database/host — can you run that pointer extraction on it for me?”
Verify API response field exists
“Here's the JSON response from our payment API — can you check whether /transaction/status exists in it and what its value is?”
Drill into array element
“I've got a JSON array of user records and I want to grab the email address of the third user — use the pointer /2/email to extract it.”
Technical details
Endpoint
POSThttps://x402-agent.kariguetoazul.workers.dev/api/json/select-pointer?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to extract a single field from a known JSON structure using a precise RFC 6901 pointer path, especially in agentic pipelines where you want a lightweight, paid micro-call rather than parsing JSON locally. Prefer this over general-purpose JSON tools when working within a Cloudflare Workers / x402 payment-gated ecosystem.
Side effects
- Pointer path not found in data — returns {"found": false} with no value
- Malformed RFC 6901 pointer syntax — may return a 400 error
- Input data too large or deeply nested beyond bounded structure limits
- Invalid JSON supplied as data — parse error response
- Payment not processed — 402 response blocking execution
