Rate Limits & Quotas
This page covers the plan differences that change how the API behaves. For prices, billing periods, and the full feature comparison, see hgraph.com/pricing.
All plans, including Free, have full access to the GraphQL, REST, and JSON-RPC APIs and the MCP server. Plans differ in throughput, in how many projects and keys you can hold, and in whether ERC and ecosystem data are reachable programmatically or only in the app.
Rate limits and quotas
Limits are enforced per API key — one requests-per-second budget shared across every network and every API, not a separate allowance per chain or endpoint.
| Free | Essential | Developer | Team | Premium | |
|---|---|---|---|---|---|
| Requests/sec | 1 | 5 | 10 | 60 | 250 |
| Monthly requests | 45k | 1M | 3M | 25M | 125M |
Paid plans have soft caps, so short spikes are tolerated; sustained overage may be metered. Exceeding your rate limit returns 429 — retry with exponential backoff. All API calls also carry a 10-second timeout.

"API" means the data is reachable programmatically with your API keys. "Playground" means it is queryable in the Hgraph App but not through your keys.
The schema reference states the access level for every table, derived from the same Hasura roles the API enforces.
