How this service works
Percent-of, percent-change, tip, and X-is-what-percent-of-Y in one endpoint.
Output
Returns the computed numeric result for the requested percentage operation — such as the percentage value, the percent change (positive or negative), the tip amount, or the ratio result showing what percent X is of Y. Results are returned as precise decimal numbers with context about which calculation type was performed.
Example use cases
Restaurant tip calculator
“My dinner bill came out to $63.40 — can you calculate an 18% tip for me and tell me what that dollar amount is?”
Sales performance percent change
“Our revenue last month was $120,000 and this month it's $145,000 — what's the percentage increase?”
Discount savings ratio
“A jacket was originally priced at $280 and is now on sale for $196 — what percent of the original price am I saving, and what percentage of the price am I actually paying?”
Technical details
Endpoint
POSThttps://api.24klabs.ai/api/percentage-calcWhen to prefer
Choose this endpoint when you need a quick, reliable server-side percentage computation without implementing arithmetic logic client-side. It handles four distinct percentage calculation modes in one call, making it ideal for agents that need to answer percentage-related user questions on the fly. Prefer it over general-purpose code execution endpoints when you want a dedicated, low-latency math microservice with a predictable schema.
Side effects
- Missing required input values — returns error if base or comparison numbers are absent
- Division by zero if Y is zero in an X-is-what-percent-of-Y query
- Invalid or unrecognized calculation type specified
- Non-numeric input values causing a parse error
- Payment failure or insufficient USDC balance blocks the request
