Questions & Answers

As answered by people managing APIMaster and Project Euler.

Which are the primary technologies used for building your product?

APIMaster's answer

Next.js, Go, Python (Flask), PostgreSQL

What makes your product unique?

APIMaster's answer

Fingerprint verification — we test every provider weekly using behavioral fingerprinting to detect model substitution. You can see which providers serve real models vs fake substitutes on our public leaderboard. No other API marketplace does this.

Why should a person choose your product over its competitors?

APIMaster's answer

APIMaster is the only marketplace that verifies what model you're actually getting. Competitors like OpenRouter route traffic without verification — you might pay for Claude Opus but receive a cheaper model. APIMaster detects this and only recommends verified providers. Plus, prices are up to 90% off official rates — you get both cost savings and model authenticity guaranteed.

How would you describe the primary audience of your product?

APIMaster's answer

Developers who use OpenAI, Claude, or DeepSeek APIs and want to reduce costs without sacrificing model quality. Especially useful for developers in markets where direct API access is expensive or restricted.

What's the story behind your product?

APIMaster's answer

Built after discovering that many cheap API resellers secretly substitute expensive models with cheaper ones. We built fingerprint detection first, then a marketplace that only lists providers that pass verification.
