Switching Tiers
Upgrade or downgrade instantly via the API. No approval process, no waiting.
# Upgrade to Performance
curl -X POST https://rpc.nodius.xyz/account/tier \
-H "Content-Type: application/json" \
-H "Authorization: Bearer YOUR_API_KEY" \
-d '{"tier": "performance"}'
# Downgrade to Standard
curl -X POST https://rpc.nodius.xyz/account/tier \
-H "Content-Type: application/json" \
-H "Authorization: Bearer YOUR_API_KEY" \
-d '{"tier": "standard"}'// Upgrade to Performance
await rpc.call("POST", "/account/tier", { tier: "performance" });
// Downgrade to Standard
await rpc.call("POST", "/account/tier", { tier: "standard" });Changes take effect immediately — rate limits, method access, and credit costs all update on the next request. Your credit balance carries over unchanged since the deposit rate is the same for both tiers.
Rate Limit Behavior
When you hit your rate limit, the server returns 429 Too Many Requests with headers:
X-Ratelimit-Limit: 50
X-Ratelimit-Remaining: 0
X-Ratelimit-Reset: 1712000001
Retry-After: 1Rate limits are per account (per public key), not per IP or per connection. The SDK handles retries automatically with exponential backoff.
