Api Endpoint

gblin.digital

Call after your agent completes an action it may later have to prove: seal the hashes of its input and output (only your action label and meta are published) into GBLIN's signed append-only transparency log and get a portable receipt: Ed25519 signature, RFC 6962 inclusion proof, C2SP signed checkpoint; root anchored daily on Base (EAS). Proves existence and time, not correctness. Free reads and demo: gblin-mcp.gblin-mcp-worker.workers.dev/log
