Straightforward billing disclosure. Two suggestions:

LOW — Consider adding a changelog entry for this fee disclosure so customers are notified via RSS/Discord.

LOW — The PR body is empty. A brief summary (e.g., "Documents the 5% fee on Unified Billing credit purchases") helps reviewers and release notes.

LOW — line 4: Update the frontmatter description to include Unified Billing so the meta description stays accurate:

LOW — src/content/docs/ai-gateway/reference/pricing.mdx line 4: Update the frontmatter description to include Unified Billing so the meta description stays accurate:

description: Review AI Gateway pricing, including free core features, persistent log storage limits, premium add-ons, and Unified Billing fees.

Review posted on PR #30934.

• Summary: The PR cleanly documents a 5% fee on Unified Billing credit purchases in two places (unified-billing.mdx intro and pricing.mdx reference). No build-breaking issues or MDX errors found.
• Labels: Attempted to add ai-gateway, but the operation was not permitted in this environment.
• Issues flagged:
  • LOW — Missing changelog entry for a customer-impacting billing disclosure.
  • LOW — Empty PR body; suggested adding a brief summary.
  • LOW — Suggested updating the description frontmatter in pricing.mdx to mention Unified Billing so the meta description stays accurate. This was posted as an inline-style suggestion in a follow-up comment.
