WhiteMagic continuity-receipt verification: POST a signed receipt bundle and receive a verdict (TRUSTED / PROVISIONAL / INSUFFICIENT_EVIDENCE / UNTRUSTED) with coded errors and an optional signed verification receipt. Verification is stateless, offline-verifiable, and fail-closed; keyless /health, /info, /revocations and GET /anchors remain free.
WhiteMagic hosted recall: read-only hybrid memory search (BM25 + vector + associative) over a curated public corpus for agent continuity. Call when an agent needs durable context from prior sessions or the public knowledge store. Keyless discovery (initialize/tools/list) is free; free evaluation keys and a daily no-key trial are available. One paid tool call per payment.
