PURPOSE + BUSINESS CONTEXT

Return the configured funding rate for a perpetual market.

WHEN THIS CALL IS USEFUL

Call this when a market-data, trading, risk, or reconciliation client needs to discover funding rates and choose a canonical record for a later step so it can understand market, order, trade, position, or collateral state without confusing a read model with execution authority.

OUTCOME · Discover

What changes

Read-only projection; it grants no mutation, settlement, traffic, or authority change.

WHY IT MATTERS

Gives people and agents a contract-backed way to discover funding rates.
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.

BEFORE YOU CALL

Authenticate at the documented boundary: bearer+scope.
Supply the required market_id (path) exactly as defined by the live contract.
Resolve the current market status, owner-specific restrictions, risk posture, and applicable trading freeze before relying on this result.

WHAT TO DO NEXT

Select one canonical identifier from the response and open its detail operation when the live contract exposes one.
Re-read the relevant market and owner-specific state before any later order or position decision, and preserve the current trading freeze.

AGENT GUIDANCE

Use funding rates only for the purpose and lifecycle stage described by this operation; do not treat it as authority for an adjacent action.
Supply the required market_id (path) exactly as defined by the live contract.
Distinguish market data, owner-specific restrictions, order admission, matching, fills, positions, collateral, cancellation, settlement, and finality; no one state implies another.
Use response links and canonical identifiers instead of constructing internal service URLs or scraping the website.

MARKET-SCOPED AVAILABILITY

Production OpenAPI presence proves that the public route is deployed; it does not unsuspend a market, admit order traffic, or select a matching engine. Catalog and read access can remain available while order entry is disabled. Matching authority, collateral reservation, settlement, and market lifecycle are independently fail-closed behind this stable contract.

MACHINE CONTRACT

The exact deployed parameters, schemas, responses, security requirements, and Hybrid-Chain agent metadata are authoritative at this operation's production OpenAPI JSON Pointer. The readable tables below add integration guidance; the deployed OpenAPI controls if guidance and the machine contract ever differ.

INTEGRATION DECISION

CALLER ACTION: Accept the returned representation or receipt, then select one canonical identifier from the response and open its detail operation when the live contract exposes one.
RETRY SAFETY: Repeat only when the integration needs a fresher authoritative projection.
STATE RECONCILIATION: Use returned identifiers and versions as the comparison point for later reads. Refresh the funding method and transfer or deposit lifecycle; compare amount, asset, network, destination, provider reference, and terminal settlement evidence.

401Authorization: Bearer is required, or the supplied credential is invalid.Authentication required · JSON RESPONSE+

{
  "code": "missing_credentials",
  "message": "Authorization: Bearer is required, or the supplied credential is invalid."
}

INTEGRATION DECISIONmissing_credentials

CALLER ACTION: Discard the rejected credential, complete the documented authentication or reassertion flow, and rebuild any request signature with fresh timestamps and nonces.
RETRY SAFETY: Retry only with a newly valid credential and fresh replay-protection values. Do not replay an expired signature.
STATE RECONCILIATION: Authentication failed before an authoritative read was returned for owner-scoped funding methods, deposit instructions, transfer intents, settlement progress, and delivery receipts.
ESCALATE WHEN: Escalate when money movement is ambiguous, provider and ledger states disagree, or a destination or asset cannot be proven exact.

{
  "code": "insufficient_scope",
  "message": "The credential lacks trading:read authority."
}

INTEGRATION DECISIONinsufficient_scope

CALLER ACTION: Verify the exact scope, tenant or workspace membership, owner boundary, step-up purpose, feature policy, and resource eligibility. Never broaden authority automatically.
RETRY SAFETY: Do not retry until the missing authority or policy condition has been deliberately resolved with least privilege.
STATE RECONCILIATION: Confirm the caller and resource resolve to the same authority boundary for owner-scoped funding methods, deposit instructions, transfer intents, settlement progress, and delivery receipts.
ESCALATE WHEN: Escalate when money movement is ambiguous, provider and ledger states disagree, or a destination or asset cannot be proven exact.

{
  "code": "market_not_found",
  "message": "The requested canonical market does not exist on the selected venue."
}

INTEGRATION DECISIONmarket_not_found

CALLER ACTION: Verify the canonical identifier and authenticated owner boundary. A 404 may intentionally conceal a resource outside the caller's authority.
RETRY SAFETY: Do not retry the unchanged identifier repeatedly. Refresh the relevant collection or lookup before choosing another identifier.
STATE RECONCILIATION: Refresh the funding method and transfer or deposit lifecycle; compare amount, asset, network, destination, provider reference, and terminal settlement evidence.
ESCALATE WHEN: Escalate when money movement is ambiguous, provider and ledger states disagree, or a destination or asset cannot be proven exact.

INTEGRATION DECISIONinvalid_market_id

CALLER ACTION: Rebuild the request from the live OpenAPI operation and correct the rejected method, media type, header, parameter, or body field.
RETRY SAFETY: Do not retry the same invalid request. A corrected read may be sent as a new attempt.
STATE RECONCILIATION: Compare the submitted values with the documented constraints before another call. Refresh the funding method and transfer or deposit lifecycle; compare amount, asset, network, destination, provider reference, and terminal settlement evidence.
ESCALATE WHEN: Escalate when money movement is ambiguous, provider and ledger states disagree, or a destination or asset cannot be proven exact.

{
  "code": "market_data_unavailable",
  "message": "The authoritative venue catalog is unavailable or has not been configured."
}

INTEGRATION DECISIONmarket_data_unavailable

CALLER ACTION: Treat the failure as transient and preserve the last known good representation without presenting it as fresh.
RETRY SAFETY: Retry with bounded exponential backoff and jitter; stop after the integration's failure budget is exhausted.
STATE RECONCILIATION: Refresh the funding method and transfer or deposit lifecycle; compare amount, asset, network, destination, provider reference, and terminal settlement evidence.
ESCALATE WHEN: Escalate when money movement is ambiguous, provider and ledger states disagree, or a destination or asset cannot be proven exact.

OPERATIONAL NOTES

Security and lifecycle guarantees

The response is a configured market projection, not evidence that a funding transfer settled.
Rates are decimal strings. An unconfigured rate returns items: [] for a valid market.
