What it means

HTTP transport layer errors when talking to an RPC endpoint.

What to do

  • HTTP 429 means you are rate limited (very common on the public endpoint); use a dedicated provider.
  • HTTP 403 often means the public RPC rejected a browser or data-centre origin; add an API-keyed endpoint.
  • 5xx responses are provider outages: retry with backoff or fail over.

Decode it locally instead

npx @solana/errors decode -- 8100003 '<base64 context>'

In development, import from @solana/kit as usual and the full message is thrown. In production the message is stripped to keep bundles small; the error object still carries error.context with the same values this page decodes, and isSolanaError(err, SOLANA_ERROR__RPC__API_PLAN_MISSING_FOR_RPC_METHOD) lets you branch on it.
