Rate limits vs credits
Rate limits are based on requests per min and are fully independent of overall credits usage. Going over your credits will not automatically trigger rate limits.
Plan update (June 2026)
The Starter (9/mo), Growth (9/mo), and Growth (49/mo) API plans are no longer offered to new customers. Existing Starter and Growth subscribers are grandfathered — they keep their plans. New customers choose between:
- Free — 10M credits/month, 10 webhooks, 5 apps, and a 600 RPM per-API-endpoint rate limit. Includes Webhooks, Hub endpoint, Indexer-as-a-Service, and all Read & Write APIs.
- Scale — $249/mo, 60M credits/month.
- Enterprise — custom limits.
See the pricing page for the full, current plan comparison.
Rate limits are set per subscription plan
- Free plan rate limits are 600 RPM or 10 RPS per API endpoint
- Scale plan rate limits are 1200 RPM or 20 RPS per API endpoint
If you need higher limits, reach out and we can set up an enterprise plan for you. Grandfathered plans (no longer offered to new customers, but kept for existing subscribers): the Starter plan is 300 RPM / 5 RPS and the Growth plan is 600 RPM / 10 RPS per API endpoint. The Free tier matches the former Growth rate limits.
API-specific rate limits in RPM
This type of rate limit is triggered when you call the same API above its API-specific threshold on your plan. As an example - On the Free plan, you can call two different APIs at 400 RPM each for a total RPM of 800 without triggering your rate limits.
| API | Free (RPM) | Scale (RPM) | Enterprise | Starter¹ (RPM) | Growth¹ (RPM) |
|---|---|---|---|---|---|
| POST v2/farcaster/frame/validate | 10k | 20k | Custom | 5k | 10k |
| GET v2/farcaster/signer | 6k | 12k | Custom | 3k | 6k |
| GET v2/farcaster/signer/developer_managed | 6k | 12k | Custom | 3k | 6k |
| GET v2/farcaster/cast/search | 120 | 240 | Custom | 60 | 120 |
| All others | 600 | 1200 | Custom | 300 | 600 |
¹ Starter and Growth are legacy plans — no longer offered to new customers, but retained for existing subscribers. The new Free tier shares the same rate limits as the former Growth plan.
Global rate limits in RPM
This type of rate limit is triggered when you call any API above the global threshold on your plan. /validate, /signer and signer/developer_managed APIs don’t count towards global rate limits.
| API | Free (RPM) | Scale (RPM) | Enterprise | Starter¹ (RPM) | Growth¹ (RPM) |
|---|---|---|---|---|---|
| Across all APIs | 1000 | 2000 | Custom | 500 | 1000 |
Cast creation rate limits
This type of rate limit depends on number of casts the account has made in a 24 hour period and its available storage.
| Casts per 24h | Available Storage Required |
|---|---|
| < 1000 | No requirement |
| ≥ 1000 | 20% of past 24h cast volume |
