  Step 2 of buying a training dataset: submit the job again with the signed X-Payment payload and the quote id.

  Create a new agent endpoint after you have obtained a valid X-Payment payload for the creation challenge. Requires a dashboard PAT with mcp:endpoints:write or mcp:*.

• request_dataset_paymentFree

  Step 1 of buying a training dataset: submit the job and get back an x402 payment challenge with the exact price. Nothing is charged and nothing is generated yet. Pass the SAME arguments to create_dataset_with_payment: the server binds the payment to this exact job and refuses a mismatch.

  Permanently delete one Agent Vault snapshot and free its storage. Irreversible — confirm with the user before calling.

  How to actually CREATE or RESTORE an encrypted backup. Encryption is zero-knowledge and must run on the machine where the agent lives — this returns the exact CLI/SDK steps.

• vault_list_agentsFree

  List the agents registered in Agent Vault for this wallet (OpenClaw, Hermes, pods, and custom --path lineages).

• vault_list_snapshotsFree

  List completed Agent Vault snapshots (encrypted backups) for this wallet, optionally filtered to one agent. Use this to check WHEN an agent was last backed up.

• vault_subscribe_proFree

  Change the wallet’s Agent Vault plan, charged from platform credits. pro = 10 GB + the last 10 snapshots of each agent ($3/month, $30/year); max = 50 GB + unlimited snapshots ($5/month, $50/year); free = cancel at period end. Yearly is two months free. Upgrades are charged immediately and prorated against the unused period; downgrades and cancellations take effect at period end. A plan change never deletes snapshots. ALWAYS confirm the plan and the charge with the user before calling.

• vault_usageFree

  Agent Vault storage usage and plan for the wallet behind a compute API key: bytes used/reserved, free vs pro plan, caps, and Vault Pro pricing.

• verify_agent_wallet_challengeFree
