ledger_rotate_secretMint a NEW agent_secret for an agent_id your workspace already owns, invalidating the old one. Use this to RECOVER an agent whose secret was lost: the previous credential stops working immediately. Requires the workspace_key that owns agent_id — an agent's own agent_secret canno…
ledger_revoke_secretInvalidate an agent_id's agent_secret WITHOUT deleting its spend history. Use when a credential may have leaked, or to stop an agent writing. Subsequent writes to that agent fail with agent_secret_mismatch until you rotate a new secret in. The agent_id stays claimed, so no other…
ledger_trackRecord a spend entry for an AI agent on any payment rail, with optional token counts. Claiming a brand-new agent_id requires your workspace_key (get one via x402 at POST /v1/billing/x402 — no human, no login — or at /start). That first call mints an agent_secret and returns it i…
ledger_set_budgetSet spending caps for an agent. Warns at 80%, blocks spend when exceeded — enforced: a ledger_track call that would cross the cap is rejected. Dollar caps (monthly_cents/daily_cents) and token caps (monthly_tokens/ daily_tokens) are independent dimensions: dollar caps only cover…
ledger_reportSpend report for an agent over a rolling window. Returns total spend, breakdown by rail and by service, budget status (ok/warning/exceeded), detected anomalies, and entry count. Requires a credential: either the agent's own agent_secret or its workspace's workspace_key (same rul…
ledger_proxy_attachPoint your provider traffic at the proxy so budget caps are enforced BEFORE the provider is contacted, instead of being reported afterwards. This closes the gap where the brake was unreachable from MCP: an agent connected over MCP could record spend (ledger_track) but nothing co…
ledger_alertsAlert history for an agent: budget warnings (80% threshold) and spending spikes. Requires a credential: either the agent's own agent_secret or its workspace's workspace_key (same rule as GET /v1/alerts).
ledger_wait_eventsLong-poll an agent's event feed — how an agent with no public URL receives alerts. Webhooks (POST /v1/webhooks) push events to a URL you own; an agent on stdio MCP cannot host one, so it waits here instead. Call this in a loop: the call holds open up to `timeout` seconds (max 30…
ledger_check_spendAsk BEFORE you spend: may this agent spend this much right now? Returns allowed (true/false), a stable reason code (within_budget, over_monthly_cap, over_daily_cap, over_monthly_token_cap, over_daily_token_cap, no_budget_set, unpriced_model), a one-line message, the cost estimat…
ledger_request_approvalAsk your workspace owner for a one-shot spend exception before a ledger_track that the cap would refuse. Creates a pending permit for exactly amount_cents on the given service. The owner (a human, or a supervisor agent holding the workspace_key) approves or denies it with ledger…
ledger_approvalsList spend-approval permits — yours, or your whole workspace's.
ledger_approval_decideApprove or deny a pending spend permit — workspace owner only. The agent's own agent_secret can REQUEST an approval but can never decide one: a credential that can approve its own requests is not a control. decision must be 'approve' or 'deny'; only pending permits can be decide…
ledger_priceWhat will this call cost? Priced from the same table the caps use. Exists because ledger_track requires the CALLER to supply amount_cents, so an agent whose spend is capped could under-report its own cost and stay under the cap. This returns the number the enforcement path would…
ledger_startGet a FREE AgentLedger workspace with no credential and no arguments — the MCP equivalent of opening POST /start in a browser. Call this FIRST if you have no credentials yet. Every other tool here (ledger_track, ledger_set_budget, ledger_report, ledger_alerts) needs a workspace_…
