Parallax

Parallax is a stablecoin-powered cross-border and B2B payments platform founded by Mika Reyes (CEO) and Alex Kuang (CTO) to remove the friction, delays, and opaque fees from international money movement across the roughly $21 trillion cross-border payments market. Serving freelancers, remote workers, and businesses in 150+ countries, Parallax let recipients get paid near-instantly in USDC, hold balances in a self-custodied wallet, and withdraw to local currency, while its first B2B product streamlined web3 companies' payables and receivables from vendor onboarding and approvals through payout and accounting. The company raised a $4.5M seed round backed by General Catalyst, Dragonfly, Circle, and gumi Cryptos Capital. Parallax was acquired by crypto wallet company Phantom, and the standalone Parallax app wound down on September 18, 2025.

Parallax is profiled on the APIs.io network. Tagged areas include Company, Payments, Cross-Border Payments, Stablecoins, and Crypto.

Regulatory Posture applies to this provider. Its tags matched the Payments regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
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.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
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/parallax: open an issue to ask a question, or submit a pull request to add artifacts.
