_ used through this hub 30 days

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • ledger_rotate_secret unknown never probed

    Mint 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 cannot rotate itself, because a leaked agent credential must not be able to lock its real owner out. Unlike ledger_track this never claims a new agent_id: an unknown id returns agent_not_claimed. The new secret is returned ONCE. Store it before you drop the response. Returns {"agent_id", "agent_secret", "_note"}, or {"error", "error_code"}.

  • ledger_revoke_secret unknown never probed

    Invalidate 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 workspace can claim it and inherit the ledger. Requires the workspace_key that owns agent_id. Returns {"agent_id", "revoked": True, "_note"}, or {"error", "error_code"}.

  • ledger_track unknown never probed

    Record 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 in the response — save it, every later call for that same agent_id must pass it back (no workspace_key needed again) or the write is rejected. Amounts are capped at $100,000/entry and must be >= 0. If a budget is set for this agent, an entry that would cross the monthly/daily cap is blocked, not just logged. Include tokens_in/tokens_out + model on every LLM call so token burn shows up in the /v1/tokens report.

  • ledger_set_budget unknown never probed

    Set 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 non-"tokens" rails, token caps only cover rail="tokens" bookkeeping rows (tokens_in/tokens_out). Set both if the agent uses both. Monthly cap is required; the rest are optional (0 = no limit). Overwrites any existing budget for the agent. Claiming a brand-new agent_id requires your workspace_key; that first call mints an agent_secret (returned once — save it); later calls for that agent_id must pass the agent_secret back (no workspace_key needed again).

  • ledger_report unknown never probed

    Spend 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 rule as GET /v1/report).

  • ledger_alerts unknown never probed

    Alert 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_list_agents unknown never probed

    Owner-only: full cross-tenant listing of every agent ever claimed on this instance, with totals. Requires the operator's admin_secret — this is a portfolio-wide view, not a per-agent report (use ledger_report for that — it requires that agent's agent_secret or its workspace_key).

    mcp-tool

    {
  "type": "object",
  "properties": {
    "admin_secret": {
      "type": "string",
      "default": "",

    arguments 11 lines
  • ledger_start unknown never probed

    Get 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_key or an agent_secret, so a caller arriving with neither must start here or it has nowhere to go. Takes NO arguments on purpose: the goal is zero friction. It returns a `workspace_key` (shown exactly once — it cannot be re-revealed, so store it before continuing) which you then send as `workspace_key` on your first ledger_track for a NEW agent_id. That first write returns the agent's own `agent_secret`, which authenticates every write after it. The free tier includes every rail, enforced budget caps, alerts, reports and the MCP server, capped at 3 agents per workspace. Minting is rate-limited per caller IP, the same limit the human door uses. Prefer to pay? POST /v1/billing/x402 with a wallet-signed payment needs no human and buys 24h of Pro (unlimited agents).

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
