Monitoring Execution

After deploying a Retroshades program you can inspect its runtime status, per-transaction execution history and aggregate statistics through two endpoints.

Program status

Returns aggregate statistics for a deployed program. Counts are computed over the 500 most recent execution records retained per program.

Endpoint: GET /retroshade/{id}/status Auth: JWT required

curl https://mainnet.mercurydata.app/rest/retroshade/1/status \
  -H "Authorization: Bearer <yourjwt>"

Response:

{
  "program_id": 1,
  "project_name": "my-retroshade-program",
  "running": true,
  "last_success_ledger": 62549580,
  "last_error_ledger": null,
  "last_error_message": null,
  "total_executions": 500,
  "total_errors": 0,
  "avg_execution_ms": 3
}

Execution log

Returns a paginated list of per-transaction execution records, newest first. Up to 500 records are retained per program.

Endpoint: GET /retroshade/{id}/executions Auth: JWT required Query params:

Param	Default	Max	Description
limit	50	200	Number of records to return
from_ledger	--	--	Return only records at or before this ledger sequence

curl "https://mainnet.mercurydata.app/rest/retroshade/1/executions?limit=10" \
  -H "Authorization: Bearer <yourjwt>"

Response:

[
  {
    "ledger_sequence": 62549580,
    "tx_hash": "3e1f7e1ceca397a70d0bb1a2bef884731809b839b865be8fb77bf55ac08abc05",
    "status": "success",
    "error_message": null,
    "rows_written": 2,
    "execution_ms": 4,
    "created_at": "2026-05-13T12:05:36Z"
  }
]

status is either "success" or "error". On error, error_message contains the failure detail and rows_written will be 0.

Per-ledger stats

Returns per-ledger aggregate stats for a program, ordered newest first. Useful for tracking throughput and spotting error spikes across ledgers. Records older than 30 days are pruned automatically.

Endpoint: GET /retroshade/{id}/stats Auth: JWT required Query params:

Param	Description
source	Filter by live or backfill (default: all)
from	Return records at or after this ledger sequence
to	Return records at or before this ledger sequence
limit	Number of records to return

curl "https://mainnet.mercurydata.app/rest/retroshade/1/stats" \
  -H "Authorization: Bearer <yourjwt>"

Response:

[
  {
    "ledger_sequence": 62549580,
    "source": "live",
    "executions": 3,
    "error_count": 0,
    "rows_written": 6,
    "total_execution_ms": 12,
    "created_at": "2026-06-12T19:26:22Z"
  }
]

source is "live" for normal ingestion and "backfill" for backfill runs.

Make sure to change the endpoint if you're on testnet.
