The Protocol

Three steps. Zero friction.

Qexur sits between your AI agents and the world — secure, fast, and fully audited.

01

Agent Sends Request

Your AI agent hits a single endpoint with an action name and parameters. No scraping, no site-specific SDKs.

02

Qexur Validates & Signs

Edge function authenticates the key, checks quota, validates parameters against the site schema, then signs with HMAC-SHA256.

03

Site Receives & Acts

Your site verifies the HMAC signature, processes the action, and responds. Everything is logged to the immutable audit trail.

Built Different

Everything you need. Nothing you don't.

Edge-Native Speed

Every request handled by a Vercel Edge Function. Zero cold starts, sub-50ms globally.

HMAC-SHA256 Signing

Every proxied request is cryptographically signed. Your site can verify it's really from Qexur.

Schema Enforcement

Owners define exactly what actions exist and what parameters they need. Agents can't hallucinate.

Immutable Audit Logs

Every call logged with agent ID, site, action, timestamp, and response status. Compliance-ready.

AES-256 Encryption

Webhook secrets are encrypted at rest using AES-256-GCM with a master key. Never stored in plaintext.

Quota Management

Every API key has configurable request limits. Automatic 429s when limits are hit. Upgrade paths built in.
