# Delx Webhook Event Normalize

> Delx Webhook Event Normalize is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-13).

Normalizes heterogeneous webhook event payloads and derives a stable fingerprint for deduplication, replay detection, and safe autonomous workflow gating.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability delx-webhook-event-normalize-bbcb274b -d '<json body>'
```

Example prompt: Normalize this incoming Stripe webhook event and give me a stable fingerprint so I can safely decide whether to act on it or treat it as a duplicate: { "type": "payment_intent.succeeded", "id": "evt_abc123", "data": { "object": { "amount": 5000 } } }.

## When to prefer this

Choose this endpoint when you need to safely normalize and fingerprint arbitrary, heterogeneous webhook payloads before an autonomous agent or workflow acts on them — especially for deduplication, replay detection, idempotency gating, or pre-mutation validation. It is ideal when you cannot trust the structure of incoming events and need a deterministic, stateless, first-party normalization step with no upstream provider calls and no billing on validation failures. Prefer it over custom normalization logic when you want a consistent fingerprint across event sources.

## Known failure modes

- Malformed or empty event object returns a structured validation failure response (not billed)
- Non-object event input returns a schema validation error
- Extremely large payloads may be rejected with a size-limit error
- Missing required 'event' field in request body returns a validation error
- Network timeout returns a connection error without charge

## How this service works

Normalize heterogeneous webhook events and derive a stable payload fingerprint. Use it before an autonomous workflow acts on untrusted input, changes an API, retries a request, or evaluates production reliability. Returns bounded machine-readable JSON for $0.002 USDC via x402 on Base. Execution is deterministic, first-party, local-only, stateless, and does not call an upstream provider; structured validation failures are not billed.

## Output

Returns a bounded, machine-readable JSON object containing the normalized event payload with standardized field names and types, a stable cryptographic or hash-based fingerprint of the payload for deduplication or idempotency checking, and structured validation metadata indicating whether the input was well-formed. Validation failures are returned as structured JSON and are not billed.
