PLANNING CONTRACT · NOT CALLABLE

This page describes intended capability and integration boundaries so people and agents can prepare safely. Do not send this request or register it as an executable tool. Wait until the capability registry marks it implemented-contract, then re-fetch the deployed OpenAPI document and build the request from that machine contract.

PURPOSE + BUSINESS CONTEXT

Planned capability: apply the requested transition to all mtf orders through the authoritative market and trading service boundary.

WHEN THIS CALL IS USEFUL

Do not call or register this operation as an executable agent tool yet. Use this page to plan the future all mtf orders workflow; enable it only after the status becomes implemented-contract and the exact operation appears in deployed OpenAPI.

OUTCOME · Planned · Create or advance

What changes

None today: this route is not executable. Its intended behavior is: creates or advances only the all mtf orders resource described by this contract after authorization, validation, policy, and idempotency gates pass.

WHY IT MATTERS

  • Lets people and agents prepare for all mtf orders without falsely presenting roadmap scope as a live capability.
  • Gives people and agents a contract-backed way to advance all mtf orders.
  • Separates decision-support and reconciliation data from the controls that admit, match, publish, or settle an order.

ISOLATION + AUTHORITY

The authenticated owner, market, order, position, matching, risk, publisher, and settlement boundaries remain distinct. Documentation, contract visibility, and read access grant no execution authority; possession of a write scope still cannot bypass market status, risk, admission, allowlist, suspension, matching, publisher, or settlement gates. Current trading, matching, prediction, ingress, publisher, allowlist, suspension, market-status, and traffic controls remain frozen unless separately approved through their controlling process. This planning record grants no runtime authority, and only deployed OpenAPI can define an executable public contract.

BEFORE YOU CALL

  • First confirm that this operation is marked implemented-contract and exists in the currently deployed OpenAPI document; until then, no production request is valid.
  • Its request and response shapes are intentionally unspecified.
  • Authenticate at the documented boundary: bearer.
  • No request shape is authoritative yet. Do not invent parameters, payloads, or response fields; wait for the operation to appear in the deployed OpenAPI document.
  • Use one Idempotency-Key only for retries of the same byte-equivalent logical mutation.
  • Resolve the current market status, owner-specific restrictions, risk posture, and applicable trading freeze before relying on this result.

WHAT TO DO NEXT

  • Keep this operation disabled in clients, agents, SDKs, and workflow automation while it remains planned-contract.
  • Use the stated owner, lifecycle, authority boundary, and provisional all mtf orders profile to prepare requirements and conformance tests without sending a request.
  • Monitor the capability registry for implemented-contract, then re-fetch deployed OpenAPI and validate its exact security, parameters, schemas, responses, and agent metadata before enabling the integration.

AGENT GUIDANCE

  • Never call this planned contract, include it in an executable tool registry, or infer runtime availability from this readable page.
  • Its request and response shapes are intentionally unspecified.
  • Use all mtf orders only for the purpose and lifecycle stage described by this operation; do not treat it as authority for an adjacent action.
  • No request shape is authoritative yet. Do not invent parameters, payloads, or response fields; wait for the operation to appear in the deployed OpenAPI document.
  • Distinguish market data, owner-specific restrictions, order admission, matching, fills, positions, collateral, cancellation, settlement, and finality; no one state implies another.
  • After a timeout or conflict, read authoritative state before deciding whether an equivalent retry is safe.
  • When implementation lands, discard generated requests based on this planning record and rebuild them from the deployed OpenAPI operation.
MACHINE CONTRACT

This operation is a non-executable planning contract. Its capability-registry record defines the intended owner, parameters, responses, and integration boundary until an implemented Rust OpenAPI operation replaces it.

EXTENDED INTEGRATION GUIDANCE

Readable request and response reference

The request body is intentionally an outline; no client should generate or send it until an owner schema is published in OpenAPI.

OPERATIONAL NOTES

Security and lifecycle guarantees

  • The Rust gateway validates the public contract and routes only to the authoritative owner; clients never address internal services directly.
  • Mutations are retry-safe only when the same Idempotency-Key and canonical request body are reused.

UPGRADING FROM V1

Legacy calls replaced by this operation

If you maintain an older integration, use this map to find the V2 replacement. Do not translate the old request field-for-field: rebuild it from the V2 parameters and schemas above because identity, authorization, replay protection, and response semantics may have changed.

POST/api/v1/exchange/cancel_allMTF: Cancel all MTF Orders
DOCUMENTATION STATUS

This planned contract now defines its public parameters, authorization boundary, replay behavior, responses, and authoritative owner. It remains non-executable until its owner adapter and conformance tests are promoted into the Rust gateway.
