GCD for Agents
x402
GCD for Agents is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-13).
Computes the greatest common divisor (GCD) of two integers and returns the result as structured JSON

How this service works
Greatest common divisor. Handy for ratio simplification, scheduling grids, or math agents without local bigint helpers. Returns GCD of two integers as structured JSON. $0.001 USDC per successful call via x402 on Base—deterministic first-party JSON, no API key, no subscription, and nothing is billed on structured validation errors.
Output
Returns a structured JSON object containing the computed GCD of the two input integers. The response is deterministic — same inputs always produce the same output. No charge is incurred on structured validation errors.
Example use cases
Fraction simplification in data pipeline
“I need to simplify the fraction 360 over 252 — can you find the GCD of 360 and 252 so I can reduce it to lowest terms?”
Scheduling grid alignment
“I'm trying to align two repeating tasks — one runs every 48 minutes and the other every 36 minutes. What's their GCD so I know when they'll sync up?”
Aspect ratio reduction for image tool
“I have an image that's 1920 by 1080 pixels. Can you compute the GCD of 1920 and 1080 so I can express the aspect ratio in its simplest form?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/gcdWhen to prefer
Choose this endpoint when your agent needs a reliable, serverless, pay-per-call GCD computation without setting up local bigint math libraries or maintaining a math microservice. Ideal for agentic pipelines doing fraction simplification, ratio normalization, or scheduling grid calculations where a deterministic first-party JSON response is required and cost is minimal at $0.001 USDC per call.
Side effects
- Non-integer inputs result in a validation error with no charge
- Missing required fields (a or b) trigger a structured error response
- Both inputs being zero is mathematically undefined and may return an error
- Overflow or out-of-range integers may not be supported depending on backend limits
