fix(credits): remove off-session credit auto-recharge - #835
Conversation
The credit gate charged a saved card off-session unless the customer had opted out of a Stripe metadata key they were never told existed (recoupable/chat#1960). Over the 30 days to 2026-08-17 it collected $0. Consent for a charge now has to be an action the account took: buying credits through POST /api/credits/sessions. - lib/credits/autoRechargeOrFail.ts -> checkCreditsAvailable.ts. The charge branch, the opt-out gate and the credit increment are gone; what remains reads the balance and reports. Renamed because a function called "autoRechargeOrFail" that never auto-recharges is the drift this issue is about. - Deleted lib/stripe/{get,set}AutoRechargeOptOut.ts, lib/billing/{get,update} AutoRechargeHandler.ts, validateAutoRechargeParams.ts, validateUpdateAutoRechargeBody.ts and app/api/accounts/[id]/auto-recharge/route.ts (GET, PATCH, OPTIONS). - Deleted lib/stripe/notifyCreditsTopupPaymentIntent.ts and its stripeWebhookHandler call. It only ever fired for PIs stamped purpose === "credits_auto_recharge", so no such PI can exist any more. Manual top-ups still notify from their checkout session and subscription charges from invoice.paid, so no surviving path loses a notification. - CREDIT_AUTO_RECHARGE_PURPOSE deleted. CREDIT_AUTO_RECHARGE_CREDITS and CREDIT_AUTO_RECHARGE_FALLBACK_SUCCESS_URL renamed to CREDIT_SHORTFALL_TOPUP_CREDITS / CREDIT_SHORTFALL_SUCCESS_URL; they still size the Checkout Session offered on a 402 and are deleted by the follow-on PR that stops minting it. - declineReason removed from the 402 envelope. It could only be produced by an off-session charge, so it is now unreachable rather than optional. It stays on POST /api/credits/sessions, where a decline still happens. chargeCustomerOffSession is deliberately kept: createCreditsSessionHandler is its second caller and that is the consented path.

📝 WalkthroughWalkthroughThe change removes automatic recharge and its API support. Credit gates now create hosted top-up sessions when balances are insufficient. Credit shortfall callers use a new success URL, and Stripe payment-intent notifications are no longer sent. ChangesCredit shortfall flow
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to The PR stops automatic off-session charges and keeps explicit top-ups, but concurrent requests can still pass the credit check without reserving balance, potentially consuming more paid service than the account can cover. Shortfall checkout completion also points to the sandbox profile URL. These bounded correctness and production-configuration issues should be fixed or explicitly accepted before merge. Poem

- In
lib/credits/ensureCreditsOrShortCircuit.ts, the first credit-gated request after a refill/subscription event can read a stale balance and incorrectly return 402 with a paid Checkout Session, risking false paywalls and failed first-run access for paying users — force a balance refresh/recompute before short-circuiting to 402. - In
lib/credits/checkCreditsAvailable.ts, the checkout sizing underestimates needed credits for artists with >4 linked profiles at 100 posts (selling 500 while cost can exceed that), so users can pay and still remain blocked — size the session to at least the computed request cost for the current profile/post count.

Valid observation, wrong PR. The gate has never been reset-aware: main's autoRechargeOrFail reads selectCreditsUsage directly too (L45-46), so a first credit-gated request after a refill boundary hits the same stale balance today. This PR changes what happens after the read, not the read. Pre-existing, not a regression — logged as a follow-up candidate on chat#1960 rather than folded into a removal PR. Worth noting the blast radius shrinks with this stack: under main the stale read could trigger an off-session charge; here it costs at most one spurious 402 until anything reads the balance.

True but pre-existing (CREDIT_AUTO_RECHARGE_CREDITS was already a flat 500 on main for the same fallback session) and deliberately not fixed here: the stacked #836 deletes the session minting from the gate entirely, so there is no session left to size. Sizing logic added now would be deleted one PR later.

Why are we redirecting to the sandbox domain? this should go to app.recoupable.dev
There was a problem hiding this comment.
Fixed in eeae2f6: CREDIT_SHORTFALL_SUCCESS_URL = "https://app.recoupable.dev". Worse than the wrong domain — sandbox.recoupable.com no longer resolves at all (connection fails), so every session's success redirect was a dead end.
Verified live on the rebuilt preview (8754d5fb → api-gd4whvaui-recoup.vercel.app): drove a 402 and fetched the minted session from Stripe directly — success_url: https://app.recoupable.dev.
Propagated to the stacked #836 as well: CREDIT_BILLING_URL is now "https://app.recoupable.dev" (a literal, no longer aliased to CHAT_APP_URL). One knock-on: the docs merged in docs#299/docs#300 show billingUrl: "https://chat.recoupable.dev" in the 402 examples — that needs a one-line docs follow-up when #836 merges.

Now https://app.recoupable.dev (Sweets). - Stale gate docstrings still described the removed auto-recharge path (validateChatRequest, ensureSocialScrapeCredits, ensureResearchCredits, validatePostResearchDeepRequest). Rewritten for the actual behaviour: a short balance 402s with a checkoutUrl and the gate never charges a card. - checkCreditsAvailable's JSDoc claimed the gate "never moves money" full stop; on a shortfall it still resolves the Stripe customer and mints the Checkout Session behind checkoutUrl. The JSDoc now says so, and notes the follow-up PR removes those writes too. - Dropped the dead incrementRemainingCredits mock and its trivially-passing assertions from checkCreditsAvailable.test.ts.

Fixed in 8754d5f, and swept for the pattern rather than just this line. Removed from this branch: the sandbox aside here, the "charge this replaces is gone" / follow-up-PR narration on checkCreditsAvailable, the "used to be described as interchangeable" history on buildInsufficientCreditsResponse, and a test comment referencing the removed opt-in path. git diff origin/main grepped for used to|no longer|previously|was removed|is gone|this replaces over added lines now returns nothing.
Applied the same sweep to the other three open branches: #836 (the "2,779 sessions" and sandbox narration on CREDIT_BILLING_URL, the "unbounded writer" history on the envelope, two test comments), #837 (the "it used to SET the plan total" paragraph on checkAndResetCredits and its test preamble), #838 (the "it used to report an expires_at" paragraph on postAdminCreditsHandler and its test comment). All four pushed, suites green.

Review findings disposition: both of Sweets' comments fixed (eeae2f60, 8754d5fb) and the deleted-code sweep applied to all four open branches. Cubic: stale comments (3×) and the dead test mock — fixed in the same commits; side-effects JSDoc — fixed (checkCreditsAvailable now states it mints the 402's session); refill-boundary stale read — pre-existing on main, logged as a follow-up on chat#1960; session sizing — mooted by #836, which deletes the session minting.
One open item for the maintainer: the merged docs show billingUrl: "https://chat.recoupable.dev" in the 402 examples; with CREDIT_BILLING_URL now app.recoupable.dev in #836, a one-line docs follow-up is needed when #836 lands.
Ready to merge.
The api returns billingUrl: https://app.recoupable.dev (CREDIT_BILLING_URL, set per review on recoupable/api#835). The 402 examples in credits.mdx and the three OpenAPI specs said chat.recoupable.dev. One-line value fix in each.
Implements the first defect in recoupable/chat#1960. Row 3 of that issue's PR matrix.
The credit gate charged a saved card off-session unless the customer had opted out via a Stripe customer metadata key (
auto_recharge_opt_out) they had to know existed to set. Over the 30 days to 2026-08-17 it collected $0. Per the decision recorded on the issue it is removed rather than inverted to opt-in: an opt-in top-up would be a feature with a known-zero conversion rate and a live card-charging blast radius.A charge now requires an action the account took:
POST /api/credits/sessions.What changes
The gate —
lib/credits/autoRechargeOrFail.ts→lib/credits/checkCreditsAvailable.tsThe charge branch (old L78-86), the opt-out consent gate (old L56) and the in-thread credit increment are gone. What remains reads
remaining_creditsand reports. 120 lines → 61.Renamed deliberately: a function called

ThebuildInsufficientCreditsResponsedocstring claiming the two shapes are interchangeable is corrected, since that claim is what invited the field onto the 402 in the first place.Verification

Flagging rather than implying it.

Summary by cubic
Removes off-session credit auto-recharge so the credit gate never charges saved cards. Previously it charged unless a hidden Stripe opt-out existed; now the gate checks balance and returns 402 with a Checkout URL, and charges only happen via
