Per-key rate limits for the v2 API

Set request ceilings on individual keys from the dashboard — defaults stay at 100 req/s, with per-key overrides on the Keys tab.

The legacy /v1/charges endpoint is retiring

v1 charges sunset on Apr 1, 2026. Migrate to /v2/payments — a migration note is on the full entry.

Rendered markdown · entry body

The typographic rhythm that is the product's whole pitch — headings, lists, code, images, the breaking callout.
⚠ Breaking change — action required

Replace calls to /v1/charges with /v2/payments before Apr 1, 2026. The response shape is unchanged; only the path moves.

You can now set request ceilings on individual API keys, directly from the dashboard. This is the most-requested control from teams running multi-tenant workloads on a shared account.

How it works

Each key inherits the account default of 100 req/s. Override any key on the Keys tab; changes take effect within a few seconds and are logged.

Setting a limit

  • Open Settings → API keys and pick a key.
  • Enter a per-second ceiling and save.
  • Watch live usage against the new ceiling on the same row.
bash
# set a 250 req/s ceiling on one key
curl -X PATCH https://api.acme.dev/v2/keys/key_8f4a2 \
  -d '{ "rate_limit": 250 }'

“Per-key limits let us give each customer their own ceiling without spinning up a second account.”
