SealVera keeps a tamper-proof, append-only record of every decision your agent makes so when an auditor, lawyer, or customer asks "why did your agent do that?" you can answer with evidence, in order, without gaps, and without anyone editing the record after the fact.
Every one of these has happened to a real team. None of them had a log.
No architecture changes. No new infrastructure. SealVera intercepts at the HTTP client level — it sees every LLM call your agent makes.
One command. Works with Node.js, Python, and any runtime that calls OpenAI, Anthropic, or OpenRouter.
npm install sealvera
Add two lines to your agent. That's it — every LLM call is now logged, signed, and visible in your dashboard.
const { SealVera } = require('sealvera'); SealVera.init({ apiKey: 'your-key', agent: 'my-agent' }); // Every LLM call is now logged and signed.
Open your dashboard. See every decision your agent made, the reasoning behind it, its token cost, and a cryptographic hash proving the record was not altered.
Built specifically for AI agents — not generic APM tools retrofitted for LLMs.
When your agent suddenly uses 3x more tokens than its baseline, you get a Slack ping. Catches runaway loops and prompt injection before the bill does.
Every decision is signed with RSA-2048. Each record references the hash of the previous one. If anyone modifies a record, the chain breaks. Exportable as CSV, JSON, or PDF.
SealVera tracks your agent's decision patterns over time. Approval rate shifted? Confidence drifted? Semantic patterns changed? You find out when it starts, not when someone complains.
Get your first agent monitored in under 5 minutes. Upgrade when you need more.

Your agents are making decisions right now. Know what they decided, why they decided it, and when something changes.
