Marturia docs

Marturia is OpenTelemetry tracing with tamper-evident receipts. You ingest spans the standard OTLP way; we hash-chain and sign every receipt with your tenant's per-key Ed25519. Anyone you share a receipt URL with can verify it offline — no Marturia account required.

15 minutes to your first verifiable receipt. Sign up → install the OTLP exporter → emit a span → generate a receipt → verify it offline. Walk through the quickstart.

What you get

OpenTelemetry observability

Standard OTLP/HTTP ingest. Use any OTel SDK in any language. We display spans, traces, services, models, costs, and errors in a dashboard built to live open all day. No proprietary instrumentation.

Cryptographic receipts

Each agent decision can be recorded as a receipt: a canonical-JSON payload, hash-chained against the previous receipt, signed by your tenant's Ed25519 key. The chain is anchored daily with a Merkle root and witness cosigning across operator nodes.

Public verifier URLs

Every receipt has a shareable URL. Send it to an auditor, a customer, or a regulator. They pip install marturia-verify, point it at the URL, and the tool confirms — offline — that the signature is valid, the chain links correctly, and the data hasn't been tampered with.

Self-host or use ours

The hosted instance at marturia.dev is the fastest path. The whole stack (ingest, signing, verifier, dashboard) is also designed for on-prem deployment — no third-party dependencies for the cryptographic core. Talk to us if you need that.
