Bright

Bright is Mexico's leading residential and commercial solar energy provider, founded in 2014 (Y Combinator W15) by Jonah Greenberger. Often described as "Sunrun for the developing world," Bright combines financing and software to let homeowners and businesses adopt rooftop solar and battery energy storage (BESS) at no upfront cost. The company operates a marketplace connecting a network of local installers, distributors, and retail promoters with customers, and offers financing models such as solar PPAs and leasing schemes. Bright's public web presence is a Wix-hosted marketing site (thinkbright.mx) covering its industrial, commercial, and home solutions, success cases, and 24/7 energy monitoring technology. It exposes an agent-facing surface via an llms.txt and a hosted Wix Site MCP endpoint, but publishes no first-party developer/REST API.

Bright is profiled on the APIs.io network. Tagged areas include Company, Solar Energy, Renewable Energy, Energy Storage, and Fintech.

Bright’s developer surface includes support and 9 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Energy & Utilities 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/bright: open an issue to ask a question, or submit a pull request to add artifacts.
