Purpose and usage

What this endpoint does

Return the verification projection for testnet supply gate attestations from the public Explorer read model, with the identifiers and verification metadata defined by the live contract.

When to use it

Call this when an explorer, wallet, indexer, auditor, or research agent needs to verify testnet supply gate attestations from its commitments, evidence state, or integrity metadata so it can resolve public network state from a machine-readable projection.

OUTCOME · Verify

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 verify testnet supply gate attestations.
Keeps website presentation separate from the stable public contract that wallets, indexers, and agents can ingest.

ISOLATION + AUTHORITY

This is a public, read-only Explorer projection. It exposes only fields admitted by the live OpenAPI schema; it grants no owner, wallet, signing, settlement, publisher, matching, or trading authority. Indexed observation time is not the same as chain finality.

BEFORE YOU CALL

No bearer credential is required; apply bounded filters and canonical public identifiers where the contract provides them.
Use the live OpenAPI schema as the authority for the exact request shape and response model.
Account for projection freshness, indexing position, and chain or domain finality in the consuming decision.

WHAT TO DO NEXT

Compare the returned commitment, signer, policy, lifecycle, and freshness fields with the caller's acceptance rules.
Follow the returned canonical identifiers and proof or related-resource links when independent verification is required.

AGENT GUIDANCE

Use testnet supply gate attestations only for the purpose and lifecycle stage described by this operation; do not treat it as authority for an adjacent action.
Use the live OpenAPI schema as the authority for the exact request shape and response model.
Treat observation timestamps, indexing position, proof state, and finality as separate facts; do not infer final settlement or authority from presence in an Explorer result.
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 the returned commitment, signer, policy, lifecycle, and freshness fields with the caller's acceptance rules.
RETRY SAFETY: For another page, send the returned opaque cursor unchanged with the same filters. Restart without a cursor when a new snapshot is required.
STATE RECONCILIATION: Use returned identifiers and versions as the comparison point for later reads. Refresh the subject, claim or credential version, issuer and reviewer authority, evidence commitment, decision, expiry, and revocation status.

{
  "code": "invalid_credentials",
  "message": "the supplied Hybrid credential is invalid"
}

INTEGRATION DECISIONinvalid_credentials

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 subject, claim or credential version, issuer and reviewer authority, evidence commitment, decision, expiry, and revocation status.
ESCALATE WHEN: Escalate when subject binding, evidence minimization, issuer or reviewer authority, decision lineage, expiry, or revocation cannot be established.

INTEGRATION DECISIONinvalid_credentials

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 subject, claim or credential version, issuer and reviewer authority, evidence commitment, decision, expiry, and revocation status.
ESCALATE WHEN: Escalate when subject binding, evidence minimization, issuer or reviewer authority, decision lineage, expiry, or revocation cannot be established.

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 subject, claim or credential version, issuer and reviewer authority, evidence commitment, decision, expiry, and revocation status.
ESCALATE WHEN: Escalate when subject binding, evidence minimization, issuer or reviewer authority, decision lineage, expiry, or revocation cannot be established.

OPERATIONAL NOTES

Security and lifecycle guarantees

EXPLORER: Testnet supply gate attestations through the canonical Hybrid-Chain V2 interface. This is a public, read-only projection; no trading or settlement mutation is performed.
The Rust gateway validates the public contract and routes only to the authoritative owner; clients never address internal services directly.
The tables and examples are derived from the current gateway source OpenAPI. Re-fetch the deployed OpenAPI before execution; deployment status is shown separately on this page.
Only parameters present in the OpenAPI operation are accepted; undocumented query keys fail closed with HTTP 422.

Reference version and availability details

This route is implemented in canonical gateway source and appears in the production OpenAPI snapshot observed 2026-10-02T23:27:55.510Z. Authentication, tenant, feature, venue, and market policy still apply.
