How this service works
Compare two strings lexicographically (-1, 0, 1). Call when you sort or branch on agent string keys. Returns cmp result 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 a single integer comparison result: -1 if string a is lexicographically less than string b, 0 if they are equal, and 1 if a is greater than b.
Example use cases
Sorting agent decision keys
“I need to sort a list of agent keys alphabetically — compare 'session_alpha' and 'session_beta' so I know which one should come first.”
Branching workflow on string order
“My pipeline needs to branch based on whether label 'gamma' comes before or after 'delta' lexicographically — can you compare them and give me the cmp result?”
Deduplication equality check
“Are the strings 'UserID_42' and 'userid_42' considered equal in lexicographic order? Compare them and return the result.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/cmp-str?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs a deterministic, stateless, single-call string comparison with no setup, no credentials, and no side effects — particularly useful in agentic pipelines where sorting or branching on string keys is needed and the cost of $0.001 USDC per call is acceptable. It is simpler than writing inline comparison logic and avoids environment-specific locale issues.
Side effects
- Missing required field 'a' or 'b' returns a 400 validation error
- Non-string inputs may cause type errors or unexpected results
- Payment failure or insufficient USDC balance returns a 402 error
- Network timeout returns a 5xx error with no comparison result
