Why do I get 429 rate limit exceeded when I’m under my monthly TU limit?
HTTP 429 with JSON-RPC error
-32005 means the Node RPC exceeded its per-second rate limit, which is separate from the monthly TU limit. The rate limit counts TUs per second, so a few expensive calls such as tenderly_simulateTransaction can reach it. Retry with a backoff and spread expensive calls over time; rate-limited requests consume no TUs. A monthly limit returns HTTP 403 with error -32004 instead. See Usage limits, rate limits, and write limits.Where can I find the Node RPC access key?

How does tenderly_estimateGas provide 100% accurate estimations?
The
tenderly_estimateGas RPC method ensures accuracy by providing enough gas so no internal calls fail.
The eth_estimateGas might underestimate the gas in case of reverts due to insufficient gas provided to the transaction.
