FAQ — Audifact

What is Audifact?

What is Audifact?: Audifact is an append-only event ledger for AI agents. Wrap your LangChain, LangGraph, LlamaIndex, or custom agent with .wrap() and every decision and outcome is recorded in a hash-chained, tamper-evident chain. Anyone can verify integrity independently via the Explorer, API, or exported snapshots.
Who is it for?: Weekend builders learning agent patterns, startups shipping product features, and enterprise teams that need audit-ready provenance for compliance and high-stakes decisions.
How do I get started?: Sign up free, grab an API key, and follow the Python quickstart or browse use-case guides.

Is there a free trial?: Yes. Every new account gets 100,000 events and 30 days to explore the platform. No credit card required to sign up.
What are monthly subscriptions?: Starter — $49/mo, 500k events per billing period.
Pro — $299/mo, 5M events per billing period.
Subscriptions renew monthly. The first month is billed when you subscribe — there is no separate paid-plan trial period.
What are Event Credits?: One-time packs that add to your extra credits balance for the current period. They stack on top of your monthly plan limit (or trial limit). Event Credits are one-time purchases and do not renew monthly. Available packs:
· 100k Event Credits — $29
· 500k Event Credits — $119
· 1M Event Credits — $219
What is the grace buffer?: If you exceed your monthly limit (or trial limit) and have no extra credits left, Audifact provides a short grace window: up to 100 additional events within the first 14 days of your billing period. This gives you time to buy credits or upgrade without an abrupt cutoff. Grace applies to the buffer only — purchased Event Credits are separate.
Where do I manage billing?: Visit Credits & Usage in your dashboard to see usage, subscribe, buy Event Credits, or open the Stripe Customer Portal.

How do I cancel?: Use Manage Subscription on the Credits page (Stripe Customer Portal) to cancel at period end.
What happens when I cancel?: Audifact uses a soft cancel: your subscription is marked canceled. Your paid Starter limits continue until the end of the billing period. You are not charged again after that date.
Can I reactivate before my period ends?: Yes. If you resubscribe to the same plan during the remaining paid period, Audifact reactivates your existing Stripe subscription — no new checkout and no immediate charge. Your billing cycle and renewal date stay the same.
What happens after my paid period ends?: Your account returns to trial limits (100,000 events). You can subscribe again or buy Event Credits anytime.

How is usage tracked?: Each billable API event submission counts toward your period usage. Your effective limit = monthly (or trial) limit + purchased Event Credits + grace buffer (when eligible). Check live numbers on Credits & Usage.
What are the warning states?: Warning — you're within 20% of your base limit, or you're drawing down extra credits.
Grace — you've exceeded your base limit and extra credits; the grace buffer is in use.
Exhausted — effective limit reached; new API submissions may be rejected.
Will my events still be accepted when exhausted?: When trial and credits are fully exhausted, the API returns 402 TRIAL_AND_CREDITS_EXHAUSTED. Subscribe, buy Event Credits, or wait for your next billing period to continue. Events already in the ledger are never deleted — the chain stays append-only.

Can events be edited or deleted?: No. The ledger is append-only. Once written, events cannot be updated or removed. Tampering with any event breaks the hash chain and is detectable on verification.
What data is stored?: You control what goes in each event — typically agent decisions, outcomes, and optional context. Public summaries can be shared via proof links; sensitive payloads stay under your API key and org.
How is integrity verified?: Each event is SHA-256 hash-linked to the previous. Independent verification is available via the Explorer, verify API, SQL replay, and periodic ledger snapshots. Proof URLs (/e/{hash}) let anyone audit a single event.
Is billing auditable too?: Yes. Credit purchases, subscription changes, and manual top-ups are recorded in an append-only billing ledger visible on your Credits page.

Which frameworks are supported?: Drop-in tracers via .wrap() for LangChain, LangGraph, LlamaIndex, CrewAI, and AutoGen. Raw SDK and REST API work for any stack.
Where are the integration guides?: Use Cases has runnable examples by audience — personal, SME, and enterprise framework pages (LangGraph, LlamaIndex, CrewAI, AutoGen).
Is there an MCP server?: Yes. Audifact exposes MCP tools for agent workflows — see the quickstart MCP section for setup.

Can I upgrade mid-cycle?: Yes. Upgrading Starter → Pro prorates the difference and keeps your billing anniversary. Manage plans from the Credits page.
