How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
Returns a JSON object with a single boolean field 'equal' indicating whether the two provided values are considered equal (e.g. {"equal": true} or {"equal": false}).
Example use cases
Verify data pipeline output consistency
“I need to confirm that the output value from step one of my pipeline exactly matches the expected reference value — can you check if 42 equals 42?”
Agent decision branching on value match
“Before I proceed, check if the user's submitted answer 'Paris' is equal to the correct answer 'Paris' so I know whether to reward them.”
Config drift detection between environments
“Can you compare these two config values — 'production' and 'staging' — and tell me if they're equal so I know if there's a mismatch?”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v1/json/equal?utm_source=zero.xyzWhen to prefer
Use this endpoint when an autonomous agent needs a cheap, stateless, pay-per-call equality check with a guaranteed JSON boolean response — especially in x402-enabled workflows on Base where you want to avoid writing inline comparison logic or when auditing equality checks via on-chain micropayments.
Side effects
- Missing one or both input fields 'a' or 'b' may return an error or unexpected result
- Comparing values of incompatible types (e.g. number vs string '1') may return false rather than coercing types
- Payment failure via x402 will prevent the call from completing
- Network timeout on the Cloudflare Worker edge node
