Billing, limits, privacy, integrations, and support — everything in one place.
What is Audifact?
- What is Audifact?
-
Audifact is an append-only event ledger for AI agents. Wrap your LangChain, LangGraph, LlamaIndex, CrewAI, AutoGen, 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 (email, or Continue with GitHub when shown), create an API key, and follow the Python quickstart or browse use-case guides.
- Can I sign in with GitHub?
- Yes. On login and signup, use Continue with GitHub when it appears. We request read-only access to your profile and verified email addresses. GitHub-verified emails count as verified on Audifact (no separate confirmation email). You can later set a password on Account settings if you also want email/password login. Google sign-in may appear when enabled for your environment.
- Do I need to verify my email?
- Email/password signups receive a verification link (check spam). API keys can only be created after the email is verified. Sign-in with GitHub (or Google, when enabled) uses the provider’s verified email, so you can create keys right away. Use Resend verification on the dashboard or Account page if you need another link.
How does billing work?
- 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 purchased Event 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 100,000 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.
Canceling & reactivating subscriptions
- How do I cancel?
- Use Manage Subscription on the Credits page (Stripe Customer Portal) to cancel at period end. For immediate termination or billing disputes, email support@audifact.io.
- What happens when I cancel?
- Audifact uses a soft cancel: your subscription is marked canceled. Your paid Starter or Pro 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?
- API event submission is blocked until you resubscribe or buy Event Credits (one-time packs add purchased balance that can still be used without an active subscription). Accounts do not automatically return to the free trial allowance. Your existing ledger history remains — the chain is append-only.
What happens if I go over my limit?
- 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 purchased Event Credits.
Grace — you've exceeded your base limit and purchased 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 purchased credits are fully exhausted, the API returns
402 TRIAL_AND_CREDITS_EXHAUSTED. When a paid subscription has ended, the API returns403 SUBSCRIPTION_EXPIREDuntil you resubscribe or buy Event Credits. 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.
Data privacy & audit guarantees
- 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 fields may include optional mirrors of decision/outcome type, value, and label (e.g.
public_decision_label/public_outcome_label) and structured JSON (public_context_json/public_output_json) shown on proof pages. Privatedecision_*/outcome_*/context_json/output_jsonstay under your API key and org (account explorer only). Large JSON is stored gzip-compressed; the event hash includes the content hash, not the full blob. - How is integrity verified?
-
Each event is SHA-256 hash-linked to the previous. Independent verification is available via the Explorer, the verify API, and exported ledger snapshots. Proof URLs (
/e/{hash}) let anyone audit a single event. Snapshotledger_hashvalues can be checked against OpenTimestamps / Bitcoin proofs — see Verify OTS anchors. - 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.
Integrations
- 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.
