FAQ

General

What is BlockReq?

BlockReq is a Web3 RPC infrastructure platform that provides blockchain node access through a simple API.

Do I need to run my own node?

No. Create an endpoint and use its RPC URL and credential.

Is there a free tier?

Yes. Eligible accounts receive 3M Requests with a 30-day validity window. No credit card is required to start.

Billing & Request Counting

What is Request Counting?

Request Counting meters distinguishable customer Requests, then applies method multipliers to Requests used. See Request Counting for HTTP, batch, and WSS rules.

What happens when I run out of prepaid Requests?

With PAYG enabled, additional Requests used accrue at $3.90 per 1M. Without Requests remaining and without PAYG capacity, authenticated calls may be rejected. You can:

1. Wait for the next free grant window if eligible.
2. Buy a self-service Request Pack from the Dashboard.
3. Top up Wallet balance and enable PAYG.

Do unused Requests roll over?

• Free grant: valid for its 30-day lot window.
• Request Packs: valid for 60 or 90 days from activation, depending on the pack.
• PAYG: usage accrues while enabled; it is not a prepaid rollover balance.

How do I check my balance?

Open the Dashboard. Requests remaining and Wallet balance are shown separately on billing and endpoint surfaces.

Technical

Which chains are supported?

See Supported Networks.

Do you support WebSocket?

Yes. A WSS subscribe or unsubscribe request counts once. Each delivered EVM eth_subscription event or Solana subscription message counts once. Ping/pong and undelivered notifications count zero.

Do JSON-RPC errors count?

A JSON-RPC application error in the response counts normally. Authentication or policy rejection, 429, and gateway 5xx count zero.
