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 with a boolean 'result' field (true if the input is a JSON array, false otherwise) and a 'schema' field identifying the response format as 'delx/util-is-json-arr/v1'.
Example use cases
Pre-processing data type guard
“Before I send this payload to the aggregator, check whether this value ["apple","banana","cherry"] is actually a JSON array so I don't cause a downstream crash.”
API response format verification
“I just got back a response from an external API and I'm not sure if the 'items' field is an array — can you verify whether {"items":[1,2,3]} contains an array value?”
Agent pipeline type assertion
“My workflow expects an array at this step but I'm getting unpredictable inputs. Can you validate whether the value I'm about to process — null — is a JSON array before I continue?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/is-json-arr?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, cheap, pay-per-use type check on a JSON value with no signup or API key required, especially in agent pipelines that process dynamic or untrusted data and need to confirm array structure before continuing. Prefer over writing inline type-check logic when auditability and verifiable delivery matter.
Side effects
- Missing or malformed 'value' field in request body may result in an error or unexpected false result
- Payment failure via x402 protocol will prevent execution
- Non-JSON request bodies will be rejected
- Extremely large nested arrays may cause latency spikes
