Solid (Solid.fi)

Solid (formerly Wise) was a venture-backed fintech-as-a-service / embedded finance platform offering banking, card, and payment APIs to fintech builders. Solid raised more than $80M, including a 2022 Series B led by FTV Capital.

As of this profile, the solidfi.com site is not responding to requests and no active API or onboarding pipeline appears to be operating. This is an honest historical record; treat any API references as unverified / inactive.

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/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/.
