Third-party certifying proxy — get an independent cryptographic proof for any HTTP call.
Works with **AI agents, webhooks, microservices, or any HTTP client**.
The proof is signed by ArkForge (independent third party) — **not by the caller**.

Why this matters
When a system makes an HTTP call, there is no independent record of what was sent, what was received, or when it happened. Either party could deny or alter the transaction.
ArkForge fixes this by acting as a **certifying proxy**: the caller routes its request through ArkForge, which signs the full request+response bundle with an Ed25519 key, timestamps it via RFC 3161, and anchors it in Sigstore Rekor — an immutable, publicly auditable log.
The resulting proof is permanently verifiable at a public URL, by anyone, without contacting ArkForge.
**This is the difference between a self-signed certificate and a CA-issued one.** Other tools produce proofs signed by the caller itself. ArkForge produces proofs signed by an independent third party.

Use cases
- **AI agents** — audit trail for every external API call (Claude, GPT, Mistral, LangChain, AutoGen)
- **Webhooks** — prove a Stripe or GitHub event was received with this exact payload
- **Microservices** — tamper-evident log between internal services (compliance, fintech)
- **Data providers** — prove an external API returned this value at this timestamp
- **Automations** — certify an action in an n8n or Zapier workflow

Tools
certify_call
Route an HTTP call through ArkForge and get a cryptographic proof of the transaction.
Returns proof_id, verification_url, upstream_response, chain_hash, timestamp, and Ed25519 signature.
**Use this instead of calling the API directly** when you need an auditable record.
Example response:
get_proof
Retrieve the full proof bundle for a given proof_id.
verify_proof
Get a human-readable summary of what a proof certifies — useful for explaining to a user or auditor what was independently verified.
get_usage
Check your remaining credits for the current month.
