Global CLI Flags

Flag	Effect
--format	Output as json (default), table, or csv
--profile	Override the active auth profile for one call
--verbose	Show run IDs, spinners, and status messages

Important: Don't use --format table as an agent unless the user specifically requests it. Otherwise, you'll be dealing with truncated responses and need to rerun queries.

Errors

Status	Action
402	Payment required — CLI handles this automatically
422	Check request format — common with history endpoints
429	Wait 1 second, then retry
500	Retry with backoff
408	Query timed out — use allium explorer status to poll

---

Best Practices

1. Batch requests — use repeatable --chain/--token-address flags for multiple tokens in one call
2. Handle 429 — exponential backoff on rate limits
3. Track spend — allium mp cost shows total spend; allium mp cost list for itemized history
4. Use --format json — pipe into jq for structured post-processing
5. Switch profiles — allium auth use <name> to change active auth; --profile <name> for one-off overrides
