Changelog

Free tier removed

2026-09-18

• The free tier is gone. Every REST request and WebSocket join now needs an active Pro subscription (1 SOL/month).
• Without one, REST returns 402 payment_required with an upgrade_url, and WebSocket joins are rejected with reason payment_required. The trial_exhausted and trial_expired WebSocket notices no longer exist.

Tiers + pricing

2026-08-11

• Free tier: all REST endpoints at 5 req/min per account, plus a 20-minute WebSocket trial per hour.
• Pro (1 SOL/month): 600 req/min and the unlimited WebSocket stream. Upgrade on the API keys page.
• Rate limit is now per account — all of your keys share it — not per key.

Versioning

The /v1/ path prefix is the API contract. Additive changes (new endpoints, new fields on existing endpoints) do not bump the version. Breaking changes (renames, type changes, removed fields) get a new prefix (/v2/) and both stay live during a deprecation window.
