Harmonic Number Sequence Generator

Use this endpoint when you need a pre-computed list of harmonic number values (partial sums of the harmonic series) up to some limit n, without implementing the computation yourself. Prefer it over general-purpose code execution when you want a simple, paid API call that returns the sequence directly. It complements the sibling prime-sequence endpoint on the same platform for mathematical sequence generation tasks.

• Missing or invalid limit n in request body — returns 400 error
• Non-integer or negative value for n — likely rejected or returns error
• Extremely large n may cause slow response or timeout
• Malformed JSON body — returns 400 or 422 error
• Payment not completed — returns 402 Payment Required
