Questions & Answers

As answered by people managing Project Euler and JoJ API.

Who are some of the biggest customers of your product?

JoJ API's answer:

  • Independent developers and startups worldwide
  • SaaS product teams integrating data APIs at scale

Which are the primary technologies used for building your product?

JoJ API's answer:

Redis and Nginx, with a custom high-performance API gateway layer. ClickHouse powers usage analytics.

What makes your product unique?

JoJ API's answer:

JoJAPI combines an API marketplace with a full monetization stack. Providers publish APIs through our gateway and get multi-dimensional metering, flexible pricing (pay-as-you-go, subscriptions, per-object billing), and monthly payouts without integrating any payment infrastructure themselves. Consumers access every API on the platform with a single API key and a shared credit wallet — no separate subscriptions per provider. The platform processes over 300 million API requests per month.

Why should a person choose your product over its competitors?

JoJ API's answer:

Unlike larger API marketplaces, JoJAPI offers a shared wallet model: you top up once and consume any API on the platform, instead of managing separate subscriptions for each API. Pricing is transparent and usage-based, with free tiers on many APIs and no credit card required to start. For providers, JoJAPI takes care of billing, metering, quota enforcement, and payouts, so publishing a monetized API takes minutes rather than weeks of payment integration work.

How would you describe the primary audience of your product?

JoJ API's answer:

Software developers, indie hackers, and product teams who need ready-to-use APIs without building their own data infrastructure — plus API providers who want to monetize their APIs through a managed marketplace.

What's the story behind your product?

JoJ API's answer:

JoJAPI was built by a solo founder who spent years building and selling APIs on existing marketplaces and kept hitting the same walls: rigid pricing models, opaque billing, and slow payouts. JoJAPI started as a better home for those APIs and grew into a full marketplace, now serving hundreds of millions of requests per month.
