Balanced

Balanced was a payments API for online marketplaces and crowdfunding platforms, founded out of Y Combinator (W2011) and backed by Andreessen Horowitz (a16z), SV Angel, Collaborative Fund, and angels including Brian Chesky and Ashton Kutcher. It offered a developer-first API for processing cards and bank (ACH) payments, paying out to sellers, and handling seller identity/underwriting for marketplaces. Balanced announced on 2015-03-13 that it was shutting down its payments platform and gave customers 90 days notice, striking a transition deal that migrated card, bank account, and seller identity data to Stripe by 2015-06-11. The company and its API are defunct; the balancedpayments.com domain is now a parked/lander page and the api/docs hosts no longer resolve.

Balanced is profiled on the APIs.io network. Tagged areas include Company, Payments, Fintech, Marketplace Payments, and ACH.

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.

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/.
