AmSC Data Movement API

Use this skill when you need to work with the AmSC movement API at https://api.american-science-cloud.org/api/current.

This skill is currently focused on the movement transfer surface. The confirmed API routes, working payloads, and tutorial collection examples are captured in the companion markdown files in this skill directory.

What the agent should do

1. Use scripts/amsc_service_client.py as the default client.
2. Treat references/endpoints.md as the source of truth for confirmed routes.
3. Use references/examples.md for the known-good tutorial collection IDs and transfer payloads.
4. Use examples/curl-examples.md when you need raw HTTP requests instead of the Python client.
5. If the client prompts for interactive Globus login, copy the login URL into login.tmp so the user can complete auth and return the authorization code.

Current configuration

Base URL: https://api.american-science-cloud.org/api/current
Resource server: 35bf38d3-4b30-42c8-ac9f-e39cec6516bf
Primary scope: https://auth.globus.org/scopes/35bf38d3-4b30-42c8-ac9f-e39cec6516bf/amsc
Client script: .claude/skills/amsc-data-movement-api/scripts/amsc_service_client.py
Token cache: .claude/skills/amsc-data-movement-api/scripts/tokens.json (written next to the client script — live credentials, never commit)

Confirmed commands

The client currently supports these five commands:

1. --transfers
2. --start-transfer '<TransferInputs JSON>'
3. --start-globus-transfer '<GlobusTransferInputs JSON>'
4. --get-globus-transfer TRANSFER_ID
5. --delete-globus-transfer TRANSFER_ID

Known working tutorial flow

The following tutorial collections are confirmed in this repo:

• Source: 6c54cade-bde5-45c1-bdea-f4bd71dba2cc
• Destination: 31ce9ba0-176d-45a5-add3-f37d233ba47d
• Source path: /home/share/godata/
• Destination path: ~/

Both of these transfer creation paths have succeeded in live testing:

• POST /movement/transfer
• POST /movement/transfer/globus

The direct Globus route may temporarily return 409 if an identical transfer is already in progress. Retrying after the earlier transfer completes is sufficient.
