Most early-stage and mid-market Indian apps don’t want the ceremony of an MSA, monthly minimum, or finance approval cycle just to start sending OTPs. Pay-as-you-go OTP APIs collapse the commitment to a wallet deposit — which is why the “no monthly fees” query is so popular.
What “No Monthly Fees” Really Means
- No minimum monthly spend.
- No platform / dashboard / API access fee.
- Charged only per OTP delivered (or attempted).
- Pre-funded wallet model.
Who This Model Suits
- Early-stage products with bursty or unknown volume.
- Side projects and indie SaaS.
- Hackathons and prototypes.
- Apps with seasonal volume (travel, ticketing, education).
Who It Doesn’t Suit
- Enterprise procurement that mandates committed contracts.
- Apps already at > 1M OTPs/month — volume contracts beat list price.
- Teams that prefer fixed monthly billing for accounting simplicity.
Pay-As-You-Go vs Subscription
| Pay-As-You-Go | Subscription | |

| Minimum spend | None | Rs 5,000–50,000+ |

Pitfalls to Watch
- Wallet expiry — read the refund policy.
- Hidden “dashboard fees” or per-API-key charges.
