A reference library for building Stripe integrations, where Stripe is a service for online payments, subscriptions, and billing. It covers API patterns, checkout, webhooks, usage-based billing, entitlements, testing, and payment-security guidance.

Use it when adding payments, customers, subscriptions, webhooks, tax, Connect, usage billing, Firebase links, pricing models, or Stripe tools for AI agents.

It keeps payment-related implementation decisions aligned with the relevant Stripe APIs and integration patterns instead of scattered or outdated advice.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00064	$0.01503
Opus 5.5	$0.00026	$0.00601
Sonnet 5.5	$0.00013	$0.00301
Haiku 4.5	$0.00006	$0.00150

Security

Grade A, and why

stripe scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

The scan reads SKILL.md. This mod also ships 6 executable files (scripts/setup_products.py, scripts/simulate_subscription.py, scripts/stripe_utils.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Stripe Knowledge Base

Unified reference for Stripe integrations. Content is split across references/ (topic-specific patterns) and scripts/ (ready-to-run helpers).

When to load which reference

Any Stripe API work -> start with references/api-cheatsheet.md and references/stripe.md
TypeScript / Next.js integration (Route Handlers, Server Actions) -> references/typescript-nextjs.md
Embedded Checkout (React mount instead of redirect) -> references/embedded-checkout.md
Webhooks in production (signature, idempotency, event catalog) -> references/webhooks-production.md
Usage-based billing / metered pricing -> references/billing-meters.md (legacy usage_type=metered was removed in 2025-03-31.basil)
Feature gating from Stripe products -> references/entitlements.md
LLM agents calling Stripe (OpenAI Agents SDK / Vercel AI / LangChain / CrewAI / MCP) -> references/stripe-agent-toolkit.md
Simulating subscription lifecycle in tests -> references/test-clocks.md
PCI DSS 4.0 / 4.0.1 compliance (SAQ-A, SAQ-A-EP) -> references/pci-dss-4-checklist.md
Subscription lifecycle -> references/subscription-patterns.md, references/usage-revenue-modeling.md
Checkout conversion optimization -> references/checkout-optimization.md
Pricing strategy and tier design -> references/pricing-patterns.md
Firebase + Stripe integration -> references/firebase-integration.md
Stripe-idiomatic patterns (reusable code) -> references/stripe-patterns.md
Cost analysis / unit economics -> references/cost-analysis.md

Reference style note: the newer references (billing-meters, entitlements, webhooks-production, typescript-nextjs, embedded-checkout, stripe-agent-toolkit, test-clocks, pci-dss-4-checklist) intentionally link to official Stripe docs for canonical code samples instead of mirroring them locally. Local content is limited to non-obvious gotchas and decision criteria.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

stripe is a skill published in the GitHub repository acaprino/daodan (9 stars, last pushed today), licensed MIT. It adds 64 tokens to every session and 1,503 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-05.
