Fastest path to a key
- npm i -g @stripe/cli
- stripe sandbox create --from-git --non-interactive (solves a proof-of-work challenge, no account, test keys saved to CLI profile)
- use the sandbox sk_test key / stripe CLI commands immediately
- optional: within 7 days a human runs `stripe sandbox claim` (browser) to turn it into a real account; then `stripe login` (pairing code) for permanent keys
- KYC / business checklive keys: activate account (business details, bank account, identity verification)
- Working API key
Biggest gap
Anonymous sandbox expires in 7 days and the MCP/CLI need an admin toggle on existing accounts; the 2026-10-31 key-policy change will break existing MCP configs using plain secret keys.
Worth copying
Anonymous, claimable sandbox (`stripe sandbox create`) gated by proof-of-work instead of signup/captcha - the agent builds first, the human claims later.
