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 | $0.00013 | $0.01346 |
| Opus 5.5 | $0.00005 | $0.00538 |
| Sonnet 5.5 | $0.00003 | $0.00269 |
| Haiku 4.5 | $0.00001 | $0.00135 |
Grade A, and why
upgrade-stripe scanned grade A with 1 finding 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.
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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts
The opening of the file, as written. The whole thing — 187 lines — stays where its author put it; the contents beside it link to each section on GitHub.
The latest Stripe API version is 2026-06-24.dahlia - use this version when upgrading unless the user specifies a different target version.
Upgrading Stripe Versions
This guide covers upgrading Stripe API versions, server-side SDKs, Stripe.js, and mobile SDKs.
Understanding Stripe API Versioning
Stripe uses date-based API versions (e.g., 2026-06-24.dahlia, 2025-08-27.basil, 2024-12-18.acacia). Your account’s API version determines request/response behavior.
Types of Changes
Backward-Compatible Changes (don’t require code updates):
- New API resources
- New optional request parameters
- New properties in existing responses
- Changes to opaque string lengths (e.g., object IDs)
- New webhook event types
Breaking Changes (require code updates):
- Field renames or removals
- Behavioral modifications
- Removed endpoints or parameters
Review the API Changelog for all changes between versions.
Server-Side SDK Versioning
See SDK Version Management for details.
Dynamically-Typed Languages (Ruby, Python, PHP, Node.js)
These SDKs offer flexible version control:
Global Configuration:
import stripe
stripe.api_version = '2026-06-24.dahlia'
Stripe.api_version = '2026-06-24.dahlia'
const stripe = require("stripe")("sk_test_xxx", {
apiVersion: "2026-06-24.dahlia",
});
Per-Request Override:
stripe.Customer.create(
email="[email protected]",
stripe_version='2026-06-24.dahlia'
)
Strongly-Typed Languages (Java, Go, .NET)
These use a fixed API version matching the SDK release date. Don’t set a different API version for strongly-typed languages because response objects might not match the strong types in the SDK. Instead, update the SDK to target a new API version.
Best Practice
Always specify the API version you’re integrating against in your code instead of relying on your account’s default API version:
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.

upgrade-stripe is a skill published in the GitHub repository bex-co/bex (574 stars, last pushed today), licensed Apache-2.0. It adds 13 tokens to every session and 1,346 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). It is 97% identical to upgrade-stripe, differing in 67 lines, and is treated as a copy.
