Service status

Check whether an operation is available and follow its progress

Service availability, launch progress and index freshness are different checks. A running API may still be unable to authorize a particular launch.

Operation	Where to check
Launch a Module Mode coin	The builder and Foundation discovery
Prepare a Custom Launch	Product discovery and its chain-specific capabilities
Follow an existing request	The status URL returned with that request
Check indexed launches	The checkpoint and data-quality fields in the selected source feed

Custom Launch availability

For Robinhood V4, publicWrites, publicAuthorization and releaseReady must be true for the version and chain entry. Use the client release advertised there. MultiRole publishes its own capabilities and request requirements.

The Custom Launch quickstart covers the workflow. The API reference explains states and error responses.

General Custom Launch Plans have a separate operation status at /v4/chains/4663/custom-launch-capabilities. Check availability.operations.create.state; preflight and reads may be active while creation reports disabled. PLAN_OPERATION_DISABLED requires a platform release change, not a different API key.

Delays and missing data

Follow a request's returned next action. A prepared package is not yet an authorized wallet transaction. Source verification follows finality and is checked separately from indexing.

Keep verified launch records when price or chart data is missing. Show missing or stale values as such. External terminals determine their own indexing schedule and trading support.
