Your agents — Claude, GPT, Mistral, your internal APIs — execute thousands of API calls. When a provider denies delivery or a client disputes the charge: who has proof?
See a live proof →Provider says it wasn't delivered. You can't prove otherwise.
Your agent did the work, but the client denies it. Without a signed proof, it's your word against theirs.
Regulator wants records. You have logs, not proof.
Your agent orders 1 server. The vendor bills you for 19. Without a neutral proof, it’s your word against theirs. With ArkForge, it’s resolved in 5 seconds.
Lawyers. 6 weeks. Invoice paid.
Dispute resolved in 5 seconds. Invoice rejected, case closed.
The proof is created after the vendor responds — it seals both sides of the exchange. If the vendor bills 19 but responded “1 confirmed”, their own response contradicts them. Not your logs. Their response.
€0.01 per proof. One avoided dispute saves thousands.
One API call. Three things happen.
The request transits through Trust Layer. Included in your monthly quota — Free (500), Pro (5,000), Enterprise (50,000), Platform (500,000).
Request relayed to target API. Response fingerprinted (SHA-256).
Ed25519 signed. RFC 3161 timestamped.
Even if ArkForge disappears tomorrow, your proofs remain verifiable. Optionally add external payment verification for a 4th layer of trust.
Origin authentication. Every proof is signed with ArkForge's Ed25519 key. The public key is published and verifiable by anyone.
Certified timestamp from a pool of WebTrust-certified authorities (FreeTSA → DigiCert → Sectigo).
Immutable transparency log entry. Every proof is appended to Sigstore's public Rekor ledger — tamper-evident and independently auditable by anyone.
Attach a Stripe receipt URL to your request. ArkForge fetches it, hashes the content (SHA-256), and binds it to the proof chain hash. The receipt becomes a 4th independent witness — tamper-proof and verifiable by anyone.
ArkForge is in the request path. It is not in the verification path.
ArkForge is a transit point. It forwards the request and records the exchange. This is where latency is added — measurable, minimizable, and independent of the proof itself.
Verification calls DigiCert, FreeTSA, or Sigstore — not ArkForge. ArkForge is absent from the verification chain. It cannot alter, revoke, or fabricate a proof after the fact.
If ArkForge goes offline tomorrow, every proof issued today remains verifiable — against public TSA keys and the Sigstore Rekor ledger. Compare with LangSmith or Braintrust: if those services close, your traces disappear. ArkForge proofs are anchored outside ArkForge by design.
For deployments that cannot route traffic through a third-party proxy: ArkForge is available as a self-hosted installation inside your VPC. You operate the proxy. You choose your TSA. ArkForge becomes the software, not the dependency. Talk to us →
Your agent calls Claude, GPT, Mistral, internal APIs, third-party services — often in the same chain. No provider certifies that chain. ArkForge certifies every hop, regardless of model or infrastructure.
Zero SDK. Two lines. Works with LangChain, AutoGen, CrewAI, or a raw HTTP call.
Some “trust layers” handle payments between agents. ArkForge is different: it’s a certifying proxy that sits between your agent and any API — proving what was sent, what was received, and when. Model-agnostic, provider-agnostic, infrastructure-agnostic. The proof works across Claude, GPT, Mistral, open-source models, and any REST endpoint — in the same chain.
Which model was called? Exact prompt? Exact response? Real cost? Agent logs are mutable. ArkForge proofs are not.
DORA, NIS2, EU AI Act require verifiable proof — not logs. ArkForge certifies every execution with a certified timestamp and anchors it in a public immutability log.
Every certified proof is indexed. Query them by date range and generate an evidence-mapping report against the regulatory framework of your choice — directly from your proof history, without manual work.

Python, TypeScript, Rust, Go — it doesn’t matter. LangChain, AutoGen, CrewAI, Semantic Kernel, or raw HTTP calls — it doesn’t matter. If your agent makes HTTPS calls, Trust Layer integrates in two lines.
No dependency to install. One header, one URL. Works with any existing HTTP library.
The original response is returned in full inside service_response.body. The proof sits alongside it — your agent extracts what it needs.
The proof is returned in the response body. Your agent can forward it, store it, or ignore it — your choice.
Before your agent delegates to an MCP server, know exactly what it can do. Trust Layer analyses the manifest, flags dangerous capability patterns, and returns a risk score — no credits consumed.
Flags dangerous capability patterns across every tool: filesystem write, code execution, environment variable access, unrestricted network calls. Know before you connect.
Compares the current manifest against your last registered baseline. If a tool silently gained new permissions between deployments, you’ll know immediately.
Detects version regressions. A server that downgrades unexpectedly is a security signal — track it, flag it, act on it.
MCP security assessments are not billed against your proof quota. Included on all plans, Free to Platform.
