Engineered for
trustless speed.
RelayBill is more than a proxy; it is a high-performance settlement layer. The protocol authenticates, bills, and secures every request in under 15ms.
The request lifecycle.
Every packet moving through the RelayBill network follows a strict cryptographic and financial audit. The gateway is optimized for negligible latency.
In-Memory Shielding
Before hitting the database, RelayBill uses an LRU cache for IP-based rate limiting at the edge, dropping abusive traffic immediately.
SSRF Protection
Target URLs are validated against private IP blacklists (localhost, 127.0.0.1, 192.168.x.x) to prevent the proxy from being used against internal systems.
Cryptographic Lookup
The x-api-key is verified against the project configuration. RelayBill checks key status, project ownership, and identity in a single optimized query.
Atomic Settlement
RelayBill wraps the balance decrement and transaction log in a strictly atomic ACID transaction. No double-spending, no data drift.
Header Scrubbing
RelayBill uses a strict whitelist approach. Only safe headers (Content-Type, etc.) are forwarded. Internal headers are stripped to prevent leakage.
Response Decoration
RelayBill returns the origin response and injects custom metadata headers like X-Relay-Duration and X-Relay-Credits-Remaining.
Built for precision.
Deployed across 250+ global points of presence. RelayBill auto-failover keeps monetized endpoints active during regional outages.
