Alterya

Alterya is an AI-powered fraud-prevention company founded in 2022 (Y Combinator; seed round led by Battery Ventures, ~$9.8M) that detects authorized-fraud scams — authorized push-payment (APP) scams, pig-butchering and romance scams, money-mule and synthetic accounts, and social-engineering-driven withdrawals — before victims send funds. It connects fraud signals across crypto rails and traditional fiat/bank rails, and prior to acquisition monitored more than $8B in transactions per month for exchanges and fintechs including Binance, Coinbase, and Block, protecting roughly 100M end users. Chainalysis acquired Alterya in January 2025 for a reported ~$150M; it now ships as the "Alterya by Chainalysis" fraud-prevention product. The standalone alterya.com domain is parked and the company operates entirely inside Chainalysis, with no independent public developer portal, API, or OpenAPI surface.

Alterya is profiled on the APIs.io network. Tagged areas include Company, Fraud Prevention, Fraud Detection, Cryptocurrency, and Blockchain.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/alterya: open an issue to ask a question, or submit a pull request to add artifacts.
