How this service works
Get object[key] with default. Call when you read optional agent JSON fields safely. Returns value, key, found for $0.001 USDC via x402 on Base. No network, no keys, no retention; first-party local JSON only. Results are advisory; the caller owns budgets, auth, and production controls.
Output
Returns a JSON object containing the extracted value for the requested key (or the caller-supplied default if the key is absent), the key that was looked up, and a boolean 'found' flag indicating whether the key existed in the original object.
Example use cases
Safe agent config field read
“Pull the 'max_tokens' field from this agent config JSON {"model":"gpt-4","temperature":0.7} and use 1024 as the default if it's missing.”
Optional field existence check
“Check whether the key 'user_id' exists in this payload {"session":"abc123","timestamp":1700000000} and give me back null as the default if it's not found.”
Fallback value for missing preference
“I have a user preferences object {"theme":"dark"} — grab the 'language' field from it and default to 'en' if it's not set.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/obj-get?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to safely read optional or uncertain fields from a JSON object without risking a key-not-found error, and wants an explicit 'found' flag alongside the value. It is especially useful for agent pipelines where JSON structure is variable and a hardcoded default is needed as a fallback. Prefer it over inline code when the agent runtime does not support safe optional-chaining or when auditability of the lookup matters.
Side effects
- Missing 'key' field causes validation error
- Non-object 'object' input causes type error
- Network or payment (x402) failure results in no response
- Invalid JSON in object field causes parse error
