How this service works
Zach Riehn's lab: an about-me and portfolio, a news desk, The Atelier for AI experiments, Launch Lab for XRP research, and Fracture for games.
Output
A JSON object containing a numeric 'result' field (the percentage value, e.g. 10 meaning 10%) and an optional 'explain' string that spells out the computation in plain language (e.g. '10.0% of 100.0').
Example use cases
Discount percentage at checkout
“I paid $35 for something originally $140 — what percentage of the full price did I pay? Use 35 as a and 140 as b.”
Test score as a percentage
“My student got 73 questions right out of 95 total — what percentage did they score? Calculate using a=73 and b=95.”
Budget spend rate
“I've spent $4,200 of my $10,000 monthly budget so far — can you tell me what percentage of the budget that is? Use a=4200 and b=10000.”
Technical details
Endpoint
GEThttps://cocoeatsai.com/area4/agent/tools/percent?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, paid, on-demand percentage computation with a built-in human-readable explanation. Useful in agent workflows where arithmetic results need to be surfaced to end users with a clear textual explanation, or when you want to offload math to an external service rather than computing inline.
Side effects
- Missing required query params 'a' or 'b' returns an error or undefined result
- Division by zero if b=0 may return an error or null result
- Non-numeric strings passed as a or b may cause a parse error
- Invalid 'mode' value may fall back to default or return an error
