Frequently Asked Questions

Got Questions? We Have Answers.

How quickly can I get production API access?
Instantly! Upon registering your account, your production API Key is immediately generated in your dashboard. You can start sending live requests with x-api-key headers right away.
What authentication mechanism does NextStepApi use?
All API requests must supply your private API key inside the x-api-key HTTP request header. We do not use Bearer tokens or complicated OAuth signature dances, keeping integration fast and painless.
How does billing and wallet deduction work?
NextStepApi operates on a transparent prepaid wallet balance with dynamic hit deductions per successful call. You only pay for what you use — there are no monthly maintenance fees or surprise invoices.
Do you offer custom TPS rate limits for high-volume enterprises?
Yes! For enterprise fintechs, NBFCs, and platforms running more than 100,000 monthly calls, our infrastructure team provisions dedicated throughput channels with custom TPS allowances and 99.9% uptime SLA commitments.
