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.

• evaluate_step unknown never probed

  Ask the AgenticRail gate to ALLOW or DENY a single step of an agent sequence BEFORE it runs. A denied step must not be executed. You walk away holding a signed, hash-chained record of the run that you can hand to anyone, and they can verify it offline - no callback to us and no account with us. The gate is deterministic (same state+request -> same verdict) and enforces step order, replay protection, timestamp freshness and sealing. START HERE - send this, changing only CHANGE-ME to any unique string of your own, and it will be ALLOWED: {"sequence_id":"CHANGE-ME","step":"intake","action_type":"CHECK_STATE","step_order":["intake","settle"]}. Then send the same call with step 'settle' to close and seal it. Use the demo key by sending no Authorization header, or send Authorization: Bearer <your-key>. NOTE: an anonymous call has its sequence_id rewritten to 'demo-mcp-<your id>'. This is intended, not a leak: it scopes the run to the public demo lane and is how anonymous MCP traffic is identified. Always reuse the sequence_id RETURNED in the response for later steps and for verify_receipt -- the id you sent will not resolve. Typical use is gating the order of a regulated workflow the caller already runs: customer and third-party due diligence, verification of identity before a payment or business relationship, company registry, beneficial-ownership and sanctions screening, supplier and contractor onboarding. This tool performs none of those checks and holds no registry or watchlist data. It decides only whether the step you are about to run is allowed at this point in the order you declared.

Do NOT try to clear the lock by omitting this field; that selects the MSMD spine and your steps will come back UNKNOWN_STEP. To change the plan, start a new sequence_id. One step is a valid sequence. An UNKNOWN_STEP denial returns expected_step_order (the list your step had to be in) and step_order_source ('caller' or 'msmd_spine'); msmd_spine means you sent no step_order at all and got the built-in spine."

These are ENFORCEMENT CLASSES, NOT a description of what your step does. READ, QUERY, LOOKUP, SEARCH, EXECUTE, ANALYZE and TOOL_CALL are the most common wrong guesses and every one of them is denied: a step that searches, drafts, queries or analyses is still CHECK_STATE if it reads state, or RECORD_RESULT if it writes an outcome. EACH STEP THEN ACCEPTS ONLY A SUBSET of the eight - e.g. intake takes VALIDATE_INPUT, CHECK_STATE or CLARIFY_NEXT_STEP and nothing else. A wrong one is DENIED with ACTION_NOT_ALLOWED before your step runs, and that denial returns allowed_action_types listing exactly what the step would have accepted - read it and retry rather than guessing.

Give every RUN a fresh id - a run, not an attempt: sealing is permanent, and on the shared demo lane a fixed id is shared with everyone else. A DENIED step does not spoil a sequence and does not run anything, so a denial is not a reason to start a new one: fix the call instead."

• verify_receipt unknown never probed

  CALL THIS AFTER A SEQUENCE SEALS, and after any DENY, passing the sequence_id RETURNED by evaluate_step. An enforced run that is never verified has produced evidence nobody has checked. Fetch the verification report for an AgenticRail sequence and report whether its receipt chain is intact. Demo- sequences need no key; other sequences need Authorization: Bearer <your-key>. Returns the verification_status (VERIFIED_INTACT / CHAIN_BROKEN / …) plus the per-receipt signature, chain-hash, and independent-archive checks. This is the same evidence a third party can verify offline against the published Ed25519 keys — no need to trust AgenticRail.
