klanex is an async execution layer between an LLM's tool-use intents and real APIs. It rejects hallucinated payloads before they ship, absorbs rate limits and outages with retries and circuit breakers, keeps a full audit trail, and reports back over signed webhooks.
# Hand klanex a tool-use intent — it validates, queues, and executes it. curl https://api.klanex.dev/v1/executions -H "X-API-Key: klx_…" -d '{ "target": { "method": "POST", "url": "https://api.stripe.com/v1/refunds" }, "payload": { "charge": "ch_123", "amount": 500 }, "payload_schema": { "type": "object", "required": ["charge","amount"] }, "callback_url": "https://you.example.com/hooks/klanex", "max_attempts": 5 }' → 202 { "execution_id": "exe_9f3…", "status": "QUEUED" } then a signed webhook: execution.completed / execution.failed
Every plan ships the full reliability engine — the tiers only change volume and limits.
Hallucinated keys are rejected in milliseconds with an llm_hint your agent can use to self-correct — before anything touches a real API.
429s, timeouts, and 5xx are retried with exponential backoff. Per-host breakers stop hammering a failing dependency.
Terminal outcomes fire an HMAC-signed callback to your backend. State is always queryable via the API too.
Target auth headers are sealed with Cloud KMS at rest and exist in plaintext only in-memory during the call. Reads are always redacted.
Every intent is stored byte-exact. Re-run hundreds of failed calls after an outage without re-prompting the model.
Pass an idempotency_key and a retried submit can never double-execute. Duplicate deliveries are harmless.
You pay for executions, not attempts — retries and schema rejections are always free.
Every plan includes the JSON-Schema gate, automatic retries with backoff and
per-host circuit breakers, HMAC-signed webhooks, KMS-encrypted credentials,
a full audit trail, and idempotent submits.
