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