Card checkout requires accepting the Terms of Use via a mandatory checkbox (Stripe native). Crypto purchases imply acceptance as noted in the Terms of Use.
The single-project unlock is purchased directly from each project page, where the premium content applies.
Payment methods
Card payments are processed by Stripe. Subscriptions renew automatically until cancelled.
Cryptocurrency payments are processed by NOWPayments as one-time passes: $29 for 30 days, $290 for 365 days, or $9 for a single project, plus applicable taxes. Crypto passes do not renew automatically; a reminder email is sent 7 days before expiry.
How access works
There is no password. You enter your email address and receive a magic login link that works on any device. Your Premium access is tied to that email address.
API access (Business)
The Business plan includes access to the CarbonMeld REST API (v1): full project data by registry code or slug (GET /api/v1/projects/<id>), filtered project lists (GET /api/v1/projects?registry=VCS&min_score=7), and market statistics (GET /api/v1/stats). Limit: 1,000 requests/day per key.
Your API key is emailed to you automatically when the Business subscription activates, and you can regenerate it at any time from your account area.
Cancellation
Subscriptions can be cancelled at any time via the Stripe customer portal. Access remains active until the end of the paid period. If a payment fails, Stripe retries automatically and access continues during the paid period.
Terms and privacy
Paid services are governed by the Terms of Use. How account and payment data is handled is described in the Privacy Policy. Scores and analyses remain informational outputs and do not constitute investment advice.
