Row 2 of the chat#2000 matrix.

The gap

credits.mdx explained what is billed, how to check a balance, and how to upgrade — but never said what a credit is worth. A consumer reading "remaining_credits": 9244 had no way to know whether that is $92.44 or $9,244 without asking.

That matters more than usual right now, because the unit is about to change.

What this adds

The unit: 1 credit = $0.01, and credit amounts are integers.

A <Note> announcing the move to micro-dollars, framed for someone integrating against us rather than for us:

  • what changes — every credit figure the API returns is multiplied by 10,000; a $92.44 balance reads 9244 today and 92,440,000 afterwards;
  • what does not — the dollar value of a balance, what anything costs, and every field name in every response;
  • what to do about it — format credit counts as currency rather than printing the integer, because a raw count is only readable while a credit happens to be worth a cent.

That last point is the one worth having in public. Anyone rendering our integers directly gets a seven-digit number the day the migration runs, and the fix is theirs to make.

Timing

Documents the unit as it is today and marks the change as planned, because it has not happened yet — database#62 is not merged and the app constants still read 100. When the cutover runs, the number in this section changes and the <Note> becomes a changelog entry rather than a warning.

Docs-first, per the house convention: this is the contract the database and app changes fulfil.

Summary by cubic

Clarifies what a credit is worth and announces a planned unit change so API balances are unambiguous and prices can match provider rates. Previously the docs did not state the unit; now they do, and we describe how figures will scale when the unit changes.

  • States the current unit: 1 credit = $0.01. API returns integer credit amounts (e.g., 9244 = $92.44).
  • Notes pricing is quoted in credits; pass-through endpoints reflect provider cost (no markup).
  • Announces planned move to micro-dollars: 1 credit = $0.000001. All returned credit figures will be multiplied by 10,000; the dollar value, prices, and field names do not change.
  • Required action: If you display credit counts, format them as currency; do not render the raw integer. Divide by the unit shown in the docs.
  • Scope: docs-only; this PR does not change API behavior. The cutover is planned and will be documented when it happens.

Written for commit e59505b. Summary will update on new commits.

Summary by CodeRabbit

  • Documentation
    • Added an explanation of credit value, including the current rate of $0.01 per credit.
    • Documented provider pass-through pricing and the planned transition to micro-dollar units.
    • Clarified that dollar balances and costs will remain unchanged, with guidance to display credits as currency.

…ange
The credits page explained what is billed and how to check a balance but
never said what a credit is worth, so an integer like 9244 had no
meaning without asking someone.
Adds that (1 credit = $0.01) and a note on the planned move to
micro-dollars: what changes for a consumer (every figure is multiplied
by 10,000), what does not (dollar value, prices, field names), and the
practical advice to format balances as currency rather than printing the
integer, since a raw count is only readable while a credit happens to be
worth a cent.

📝 Walkthrough

Walkthrough

The credit documentation defines the current value of one credit, explains provider cost pass-through, and documents a planned conversion to micro-dollar units. It also states the API multiplier, unchanged monetary values, unchanged field names, and currency display guidance.

Credit valuation

Layer / File(s)Summary

Adds the current credit value, provider pass-through pricing, planned conversion to $0.000001 units, 10,000× API counts, unchanged dollar semantics and field names, and currency display guidance.

Estimated code review effort: 1 (Trivial) | ~2 minutes

Merge Risk:🟡 Moderate · up to e5950

The documentation currently instructs integrators to convert credit balances incorrectly and leaves the request-side unit ambiguous during the planned migration, which could lead to incorrect displayed balances or mismatched API integrations. Merge should wait until these instructions are corrected.

Document the request-side credits unit.

The OpenAPI contract defines credits: 250 as $2.50 and states that creditsPurchased matches the request. Either scale both values by 10,000, or explicitly preserve the request-side cent unit and update the response contract.

**What does not change:** the dollar value of your balance, what anything costs, and every field name in every response.

If you display credit counts to your own users, format them as currency rather than printing the integer — a raw count is only readable while a credit happens to be worth a cent. Divide by the unit above.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Use multiplication for the currency conversion.

“Divide by the unit above” is incorrect. The unit is dollars per credit. Use credit_count × dollars_per_credit: 9244 × 0.01 = $92.44 today and 92,440,000 × 0.000001 = $92.44 after migration.
