Purpose and usage

What this endpoint does

Return one workspace-owned delivery contract with lifecycle timestamps, plan limits, entitled feeds, current-month usage, and commercial contract posture.

When to use it

Use after list discovery or after a lifecycle operation to reconcile the exact plan, entitled feeds, timestamps, metering, and commercial posture of one workspace-owned delivery contract.

OUTCOME · Inspect

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 inspect subscription.
Makes feed provenance, quality, delivery entitlement, replay limits, and workspace-owned composite policy explicit before price data enters valuation or decision workflows.

ISOLATION + AUTHORITY

Instrument, provider, observation, signature, hash-chain, aggregation, composite owner, subscription, delivery, billing, valuation, market, and trading boundaries remain distinct. A feed, snapshot, replay, plan, or subscription supplies data only and grants no oracle-finality, valuation approval, publisher, order, matching, settlement, or trading authority.

BEFORE YOU CALL

Authenticate at the documented boundary: bearer+scope.
Supply the required subscription_uuid (path) exactly as defined by the live contract.
Resolve the canonical instrument and feed, source and aggregation policy, required freshness and quality, and any subscription entitlement or replay window.

WHAT TO DO NEXT

Compare lifecycle state, entitled feeds, plan limits, replay window, usage, and billing posture before changing delivery behavior.
Open the exact feed contract for each entitlement and verify observation provenance independently of subscription status.

AGENT GUIDANCE

Use subscription only for the purpose and lifecycle stage described by this operation; do not treat it as authority for an adjacent action.
Supply the required subscription_uuid (path) exactly as defined by the live contract.
Preserve decimal values and observation timestamps exactly; distinguish source time, ingestion time, sequence, freshness, health, quality, aggregation, delivery entitlement, and business acceptance.
Use response links and canonical identifiers instead of constructing internal service URLs or scraping the website.

INTEGRATION DECISION

CALLER ACTION: Accept the returned representation or receipt, then compare lifecycle state, entitled feeds, plan limits, replay window, usage, and billing posture before changing delivery behavior.
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 feed, source mapping, observation timestamp, quality and staleness state, policy version, and delivery or command receipt.

404The subscription does not exist in the authenticated workspace.Resource not visible · JSON RESPONSE+

{
  "code": "price_feed_subscription_not_found",
  "message": "The subscription does not exist in the authenticated workspace."
}

INTEGRATION DECISIONprice_feed_subscription_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 feed, source mapping, observation timestamp, quality and staleness state, policy version, and delivery or command receipt.
ESCALATE WHEN: Escalate when source identity, observation time, confidence, staleness, entitlement, or delivery evidence cannot be reconciled.

401The bearer credential is missing, expired, or invalid.Authentication required · JSON RESPONSE+

{
  "code": "invalid_credentials",
  "message": "The bearer credential is missing, expired, or invalid."
}

INTEGRATION DECISIONinvalid_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 workspace price-feed definitions, source mappings, observations, quality status, subscriptions, and delivery receipts.
ESCALATE WHEN: Escalate when source identity, observation time, confidence, staleness, entitlement, or delivery evidence cannot be reconciled.

403The credential lacks pricing:read or the subscription does not entitle this replay.Authority or policy denied · JSON RESPONSE+

{
  "code": "insufficient_scope",
  "message": "The credential lacks pricing:read or the subscription does not entitle this replay."
}

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 workspace price-feed definitions, source mappings, observations, quality status, subscriptions, and delivery receipts.
ESCALATE WHEN: Escalate when source identity, observation time, confidence, staleness, entitlement, or delivery evidence cannot be reconciled.

503The authoritative Core pricing projection is unavailable.Dependency unavailable or outcome uncertain · JSON RESPONSE+

{
  "code": "price_feeds_unavailable",
  "message": "The authoritative Core pricing projection is unavailable."
}

INTEGRATION DECISIONprice_feeds_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 feed, source mapping, observation timestamp, quality and staleness state, policy version, and delivery or command receipt.
ESCALATE WHEN: Escalate when source identity, observation time, confidence, staleness, entitlement, or delivery evidence cannot be reconciled.

OPERATIONAL NOTES

Security and lifecycle guarantees

Fetch this detail after list discovery and again after any future lifecycle transition; use returned state and timestamps rather than predicting them client-side.
Do not infer delivery fitness from status alone. Confirm the requested feed is present and enabled and that plan cadence, replay, and retention limits meet the consuming policy.
Usage and billing fields describe metering and commercial posture, not invoice payment, external settlement, or authority to move value.
The bearer-derived workspace is enforced at the authoritative query. Another workspace's identifier is not disclosed; responses are no-store.

Reference version and availability details
