How this service works
Generate the Collatz sequence for a given number up to a specified limit.
Output
Returns the Collatz sequence as an ordered list of integers starting from the given number, following the rule: if even divide by 2, if odd multiply by 3 and add 1, continuing until reaching 1 or hitting the specified limit.
Example use cases
Visualizing Collatz stopping time
“Generate the Collatz sequence for the number 6171 and show me all the steps until it reaches 1, with a limit of 500 steps.”
Math education sequence demo
“I'm teaching number theory — can you generate the Collatz hailstone sequence for 12, limiting it to 50 steps, so I can walk students through each iteration?”
Checking convergence for large number
“Run the Collatz sequence for the number 837799 up to 1000 steps and tell me how many steps it takes to reach 1.”

Endpoint
POSThttps://sovereign-x402-zeta.vercel.app/api/v1/sequence/collatz_conjecture?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need the full enumerated Collatz sequence for a specific starting number, especially when you want step-by-step tracing or need to apply a limit on iterations. Prefer over manual computation for large starting values where the sequence can be hundreds of steps long.
Side effects
- Invalid or missing starting number returns an error
- Non-positive or non-integer input may be rejected
- Limit set too low may truncate sequence before reaching 1
- Payment failure (402) if USDC funds are insufficient
- Malformed request body returns 400 error
