Rate limits & quotas
Limits apply per user account, aggregated across all API keys. Same rules for https://api.tools.town and MCP.
- Compute free pool
- 500 units / month
- Shared across all T0–T2 compute tools (calculators, text, JSON, etc.).
- Image free pool
- 50 units / month
- Image-class tools on api.tools.town.
- AI class
- Metered
- AI endpoints debit ai_tokens or api_request per call — no free pool.
- Rate limit
- 60 requests / minute
- Per API key, across all endpoints.
- Overage
- Prepaid packs
- When a free pool is exhausted, calls debit api_request credits (weighted by tool tier).
- Auth
- Bearer API key
- Create keys at tools.town/account/api-keys with tools:compute / tools:image / tools:ai scopes.
