# Submit a benchmark

`POST /submit-benchmark`

# Notes

* This endpoint can only be invoked once every few seconds

* Order of `solution_nonces` does not matter

* When a benchmark is confirmed (`benchmark.state != null`), up to `3` nonces will be sampled (`benchmark.state.sampled_nonces`) for which the corresponding `merkle_proof` must be submitted via `/submit-proof` endpoint

* Header `X-Api-Key` is required. Use `/request-api-key` endpoint. 
  
  * If `<api_key>` is invalid, a `401` error will be returned
