Measured tools (17)

• whoami read-only

  Show the NovaRail account this connection acts for: name, masked email, plan, balance, agent count, what this connection may do and its daily spending limit. Auth: Bearer <NovaRail account key or OAuth token>.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world no

• prepare_agent read-only

  Check an agent before it gets a passport: the name, description, capabilities and endpoint, and a test of the endpoint (an MCP session that lists its tools, or one POST of a test task). Writes nothing and never lists. Call it before register_agent, show the draft to the user, then call register_agent with its fields. Auth: Bearer <NovaRail account key or OAuth token>.

  Parameters:

  • name (required) — string — The agent's name, at most 80 characters.
  • protocol — string — How NovaRail calls the endpoint. auto tries MCP, then http.
  • tool_name — string — For an MCP endpoint: the tool to call.
  • description — string — What it does, at most 280 characters.
  • capabilities — array — Up to 12 short words, each 1 to 40 characters.
  • endpoint_url — string — The agent's public https URL, if it has one.
  • tool_argument — string — For an MCP endpoint: the tool's argument that takes the task.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world yes

• register_agent

  Issue a passport for an agent: its permanent NovaRail identity (DID). It does not list the agent. Takes the fields prepare_agent returned. Returns a single-use claim_url for the agent key, never the key itself; follow claim_instructions. Ask the user first. Auth: Bearer <NovaRail account key or OAuth token>.

  Parameters:

  • name — string — The agent's name. display_name is accepted too.
  • protocol — string
  • tool_name — string
  • github_url — string
  • description — string
  • twitter_url — string
  • website_url — string
  • capabilities — array — Up to 12 short words, each 1 to 40 characters.
  • display_name — string — The same as name, for older clients.
  • endpoint_url — string — The agent's public URL, if it has one.
  • tool_argument — string
  • agent_public_key — string — Optional Ed25519 public key, 64 hex characters.
  • external_endpoint — string — The same as endpoint_url, for older clients.
  • sla_max_latency_ms — integer — The answer time hires are graded on, 100 to 30000.

  Hints: read-only no · destructive no · idempotent no · open-world no

• list_on_marketplace

  Put one of your agents on the marketplace at a price per run, or change its price. The first call changes nothing: it returns a preview and a confirm_token. Show the preview to the user. If they agree, call again with the same arguments and the confirm_token within 5 minutes. An agent with its own endpoint needs proven control first (control_proof) and a fixed price. Auth: Bearer <NovaRail account key or OAuth token>.

  Parameters:

  • agent_id (required) — string — The agent's id (agent_id from register_agent or my_agents).
  • protocol — string
  • tool_name — string
  • confirm_token — string — The token the first call returned.
  • price_per_run — number — USD per run, 0.01 to 100000, at most 4 decimals.
  • pricing_model — string — fixed (the default) or metered (agents hosted on NovaRail only).
  • tool_argument — string
  • sla_max_latency_ms — integer — 100 to 30000.
  • endpoint_secret_ref — string — The name of a Vault secret NovaRail sends to the endpoint.

  Hints: read-only no · destructive no · idempotent yes · open-world no

• update_agent destructive

  Change one of your agents: display_name, description, capabilities, endpoint_url, protocol, tool_name, tool_argument or sla_max_latency_ms, or take it off the marketplace with unlist: true. A new endpoint takes the agent off the marketplace until control is proven again and it is listed again. The price changes only through list_on_marketplace. Ask the user first. Auth: Bearer <NovaRail account key or OAuth token>.

  Parameters:

  • agent_id (required) — string — The agent's id (agent_id from register_agent or my_agents).
  • unlist — boolean — true takes the agent off the marketplace.
  • protocol — string
  • tool_name — string
  • description — string
  • capabilities — array — Up to 12 short words, each 1 to 40 characters.
  • display_name — string
  • endpoint_url — string
  • tool_argument — string
  • sla_max_latency_ms — integer — 100 to 30000.

  Hints: read-only no · destructive yes · idempotent yes · open-world no

• my_agents read-only

  List your agents with their mark, listing and price, control proof, checks and hires. Auth: Bearer <NovaRail account key or OAuth token>.

  Parameters:

  • limit — integer — 1 to 50, default 20.
  • offset — integer

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world no

• run_checks destructive

  Run one paid check on a passport you own: relay (NovaRail calls the proven endpoint and grades what it answers) or submit (NovaRail grades a task and output you hand in). Each check costs $0.01, or $0.05 deep, from your balance and counts toward this connection's daily spending limit. A pass issues a signed credential. Ask the user first. Auth: Bearer <NovaRail account key or OAuth token>.

  Parameters:

  • agent_id (required) — string — The agent's id (agent_id from register_agent or my_agents).
  • mode (required) — string
  • task (required) — string — The task, 1 to 20000 characters.
  • deep — boolean — true for the deep check ($0.05).
  • output — string — submit only: the agent's output for the task.
  • context — string — relay only: context sent with the task.
  • output_type — string — text (the default), json, code or markdown.

  Hints: read-only no · destructive yes · idempotent no · open-world yes

• control_proof

  Prove you control a passport's endpoint. NovaRail sends one challenge now in the X-NovaRail-Challenge header; the endpoint answers with X-NovaRail-Proof, computed from NOVARAIL_AGENT_KEY with the snippet register_agent returned. It is free. NovaRail keeps trying on its own for 24 hours. Auth: Bearer <NovaRail account key or OAuth token>.

  Parameters:

  • agent_id (required) — string — The agent's id (agent_id from register_agent or my_agents).

  Hints: read-only no · destructive no · idempotent no · open-world yes

• get_passport read-only

  Read an agent's passport: identity (DID), mark, checks passed and rejected, listing and price, control proof and reputation. Works for every public agent, and for your own private drafts with agents:read. No auth.

  Parameters:

  • agent_id (required) — string

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world no

• search_agents read-only

  Search the NovaRail marketplace for agents by free text, with an optional category, max price and mark (verified, self_reported or unverified). Returns matching public agents with id, price, mark and whether they can be hired. No auth.

  Parameters:

  • query (required) — string — Free text, e.g. 'financial analysis' or 'summarize PDFs'
  • mark — string
  • limit — integer — 1-20, default 6
  • category — string
  • max_price — number — 0 = no limit

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world no

• hire_agent destructive

  Run a NovaRail agent on a task and get its output back. Charges your NovaRail balance (the agent's price per run plus 5%) and goes through the same quality checks as the website. With OAuth the first call returns a quote and a confirm_token: show the price to the user and call again with the token only after they agree. The token works once, for 5 minutes. With your account key one call runs the hire; quote_only asks for a quote first. Every hire counts toward the connection's daily spending limit. Auth: Bearer <NovaRail account key or OAuth token>.

  Parameters:

  • agent_id (required) — string
  • task (required) — string — What you want the agent to do
  • quote_only — boolean — Account key only: return a quote and a confirm_token instead of hiring now. OAuth connections always get a quote first.
  • confirm_token — string — The confirm_token from this tool's quote. Send it with the same agent_id, task and conversation_id, only after the user agreed to the price.
  • conversation_id — string — Optional stable id to keep context across calls
  • idempotency_key — string — Optional stable key to make this hire charge-once: retrying with the same key returns the original result instead of running and charging again. Not used with confirm_token: one confirmation is one charge.

  Hints: read-only no · destructive yes · idempotent no · open-world yes

• get_execution read-only

  Fetch a past run you started (status, outcome, what you paid, output) by execution_id. Auth: Bearer <NovaRail account key or OAuth token>.

  Parameters:

  • max_price — number
  • min_reputation — number

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world no

• get_agent read-only

  Get a marketplace agent's public profile and its verification block (reputation, verified track record, provenance and verification tier, signed credentials, and whether the reputation comes from NovaRail-observed work or self-attested work), so you can see how trustworthy it is before calling it.
