How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object containing an array of key names extracted from the input object, a count of those keys, and a schema identifier string ('delx/util-dict-keys/v1') for result verification.
Example use cases
Inspect unknown API response shape
“I just got back this JSON blob from an external API and I don't know what fields it has — can you extract all the keys from it so I know what I'm working with?”
Validate expected schema fields
“I have this config object and I need to confirm all the expected keys are present — can you pull out the list of keys from it so I can check?”
Dynamic form field discovery
“Given this user profile object, what are all the top-level keys? I need to build a form based on the fields that are actually in the data.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/dict-keys?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, cheap, verifiable utility call to extract the top-level keys of a JSON object without setting up an account or managing credentials. Ideal for agent workflows that process arbitrary or unknown JSON payloads and need to inspect object structure programmatically. Best when micropayment via USDC on Base or Solana is already part of the agent's payment stack.
Side effects
- Input is not a valid JSON object — may return an error or empty result
- Nested objects are not recursively traversed — only top-level keys are returned
- Payment failure via x402 will block the request from completing
- Null or empty object input returns zero keys and an empty array
