## Top Questions

<Accordion title="How do I get a Helius API key?">
  Sign up at [dashboard.helius.dev](https://dashboard.helius.dev) and create a
  project — your API key is shown in the dashboard and can be used as a query
  parameter (`?api-key=YOUR_API_KEY`). You can also create accounts and keys
  programmatically via the [Helius CLI](/agents/cli) or [MCP
  server](/agents/mcp).
</Accordion>

<Accordion title="What are credits and how do they work?">
  Helius bills API usage in credits — each method has a specific credit cost.
  Your plan includes a monthly credit allowance that resets each billing cycle
  (unused credits do not roll over). See the [credits page](/billing/credits)
  for the full cost table per method, and [autoscaling](/billing/additional-credits) if
  you need to exceed your plan limits.
</Accordion>

<Accordion title="What's the difference between standard RPC and the DAS API?">
  Standard RPC methods are raw Solana JSON-RPC calls (`getAccountInfo`,
  `getTransaction`, etc.). The [DAS API](/das-api) is a higher-level, unified
  interface for querying Solana digital assets — NFTs, compressed NFTs, and fungible
  tokens — with enriched metadata, ownership, and pricing data
  in a single structured response.
</Accordion>

<Accordion title="Which plan should I choose?">
  The Free plan is suitable for development and testing. For production
  workloads, paid plans offer higher credit allowances, higher rate limits on
  Enhanced APIs (DAS, Priority Fees, Enhanced Transactions), and staked
  connections for reliable transaction landing. See the [pricing
  page](https://www.helius.dev/pricing) and [plans overview](/billing/plans) for
  a detailed comparison.
</Accordion>

<Accordion title="What's the difference between Webhooks, LaserStream WebSocket, and LaserStream gRPC?">
  **[Webhooks](/webhooks)** push events to a public HTTPS endpoint you operate —
  ideal when you want events delivered to your server without holding a
  connection open. **[LaserStream WebSocket](/rpc/websocket)** streams events
  over a persistent WebSocket connection — ideal for apps using the standard
  Solana WebSocket interface or Helius extensions like `transactionSubscribe`.
  **[LaserStream gRPC](/laserstream)** is the gRPC variant with historical
  replay and multi-region failover — ideal for large-scale pipelines that need
  the richest feature set. LaserStream WebSocket and LaserStream gRPC share the same
  backend; Webhooks run on a separate delivery pipeline.
</Accordion>

<Accordion title="Do you support Devnet?">
  Yes. Use `https://devnet.helius-rpc.com/?api-key=YOUR_API_KEY` for Devnet RPC
  calls. A Devnet SOL faucet is available in your
  [dashboard](https://dashboard.helius.dev/faucet) on paid plans — see the
  [Devnet SOL guide](/rpc/devnet-sol) for more options.
</Accordion>

<Accordion title="What happens if I run out of credits?">
  Requests return a `429 max usage reached` error once your credits are
  exhausted. To avoid interruptions, enable [autoscaling](/billing/additional-credits)
  on fiat plans, or [purchase prepaid
  credits](/billing/additional-credits#crypto-plans) on crypto plans.
</Accordion>

<Accordion title="Where can I check service status?">
  Real-time status and incident history are published at
  [helius.statuspage.io](https://helius.statuspage.io). See the [status page
  guide](/support/status-page) for details on subscribing to incident
  notifications.
