How this service works
Machine-buyable infrastructure for autonomous agents: API cost routing, margin optimization, funding-rate data, webpage extraction, result verification, spend controls, retry planning, state, tender search and GitHub bounty intelligence.
Output
Returns a JSON object with ok:true, mode 'json_pointer_extract', a results array where each element has the requested path, a boolean 'found' flag, and the resolved value (if found), plus a total found_count integer.
Example use cases
Extract user fields from API response
“I just got back a big JSON response from an API and I need you to pull out /user/name and /user/email from it — can you extract those two fields for me?”
Verify nested config key exists
“Check whether the path /config/database/host exists in this JSON config object I'm passing you, and if so, return its value.”
Batch-pull multiple values from payload
“Here's a JSON order payload — please extract /order/id, /order/total, and /order/status all at once so I can log them.”
Technical details
Endpoint
POSThttps://bounty-engineer-x402-prod.onrender.com/v1/json-pointer-extract?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to extract one or more specific fields from a JSON document using standard RFC 6901 JSON Pointer syntax, especially when multiple paths must be resolved in a single call. Prefer it over writing inline parsing code when operating inside an autonomous agent pipeline that needs reliable, structured extraction with explicit found/not-found signals per path.
Side effects
- Path not found returns found:false with no value for that path
- Malformed JSON Pointer syntax may cause path resolution errors
- Invalid or non-JSON input value causes extraction failure
- Empty paths array returns empty results with found_count 0
- Payment failure (HTTP 402) if USDC balance is insufficient
