The 30-day pass
| Product | Price | Access |
|---|---|---|
| 30-day pass | €9 + VAT by card · $9 in crypto | All premium content of every rated project, PDF reports and API access for 30 days. One-time payment, no auto-renewal. |
There is no subscription. Buying another pass while yours is still active adds 30 days on top of the current expiry, so renewing early loses nothing. We email you a reminder 3 days before your pass expires.
Fair use: a pass covers up to 30 different projects per day across the site, PDF reports and the API. Opening the same project again on the same day does not count twice; the counter resets at 00:00 UTC.
Portfolio and comparison
My portfolio keeps up to 20 projects you hold or follow. They are always available and do not count towards the 30 projects per day. We check them every hour and email you when a score, the red flags, the registry status or the CORSIA / CCP / Article 6 labels change. To keep the portfolio from becoming a way around the daily limit, you can make up to 10 changes (additions or removals) per week.
Check an offer: paste an offer you received and we screen it against the registry records CarbonMeld holds — is the project registered, was the vintage issued and how does the snapshot's issuance balance (issued − retired − cancelled) compare with the offered quantity, are the CORSIA, CCP and Article 6 claims backed by the registry's own labels. Up to 20 checks per day. This compares the offer's claims with held records: it does not verify exact serial numbers, the seller's title or actual tradability.
Compare projects puts up to 10 projects side by side and tells you when their scores come from different versions of our methodology; save it as PDF from your browser's print dialog. Anyone can compare the public data; the pass adds per-dimension scores, red-flag details and risk indicators.
Payment methods
Card payments are processed by Stripe. VAT is calculated at checkout based on your country. Companies can enter their VAT number at checkout and receive an invoice by email.
Cryptocurrency payments are processed by NOWPayments: $9 one-time for the same 30-day pass. An email address is required so we can deliver your login link.
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.
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
Your 30-day pass includes REST API v1 and the MCP server, using the same Bearer key. Generate your key on your account page. Limits and setup are in the guides.
Nothing to cancel
Passes never renew automatically, so there is nothing to cancel: access simply ends at the expiry date unless you buy another pass. Premium content is digital content delivered immediately; as stated in the Terms of Use, sales are final and not refundable.
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.
