Platform Features

Engineered for Speed, Reliability & Scale

DevLabs is Powered by Cloudflare, leveraging global edge technology to deliver ultra-low latency spatial intelligence, extreme speed, and modern developer infrastructure.

Sub-15ms Edge Execution

Powered by Cloudflare's global edge network, routing queries to nearby edge nodes and terminating TLS in milliseconds for peak speed and sub-15ms client responsiveness.

Multi-Stop TSP Route Optimization

2-Opt Traveling Salesperson Problem solver rearranges multiple delivery waypoints into the optimal shortest path order, cutting drive distance and dispatch costs.

Turn-by-Turn Dynamic Navigation Cues

Emits granular distance maneuver cues (100m, 50m, 10m, turn now) with heading degrees and street names, ready for integration into mobile navigation clients.

Live Telemetry & WebSocket Streaming

Real-time per-second API throughput, p95 latency tracking, status code monitoring, and live WebSocket telemetry feeds available directly inside the developer dashboard.

Budget Governance & 5-Day Grace Period

Set custom monthly USD spending limits with 80% email warnings, and automated PDF invoice generation with a 5-day grace period.

Enterprise Security & Scoped API Keys

Time-limited email 2FA verification codes secure authentication. Generate scoped live secret keys (lw_live_...) per project with instant revocation.

Developer Platform Architecture

Pure edge technology with zero idle overhead.

Powered by Cloudflare, all requests hit global edge PoPs, validating API keys and enforcing rate limits in memory before executing spatial queries. Responses return instantly with compressed JSON payloads and extreme edge speed.

Frequently Asked Questions

Common questions regarding quotas, invoices, and metered rates.

How does billing and the 20,000 monthly quota cap work?

All production API gateway requests are billed transparently on a metered pay-as-you-go basis per 1,000 calls. To protect accounts from runaway spend or unintended script loops, all new accounts start with a default safety quota cap of 20,000 requests/month (and 60 requests/hour), which can be upgraded anytime.

Are there any free requests included?

Yes! Every account includes 50 free requests per day per endpoint exclusively within the interactive map test bench. Standard API calls from your applications are billed at published rates per 1,000 calls.

Can I set a spending cap to avoid unexpected bills?

Yes! Inside Account Settings, you can configure a custom monthly USD budget limit. You will receive an automated email alert when reaching 80% of your budget.

What is the invoice grace period?

Monthly invoices are issued on the 1st of each month with an automated 5-day payment grace period before any services are suspended.

4. Turn-by-Turn Navigation Distance Cues

The multi-stop route endpoint returns a structured distanceCues object. As a client vehicle moves along an active road corridor, driver guidance can be delivered automatically at exact spatial alert thresholds:

in_100m

100m Ahead

Prepares driver: "In 100 meters, prepare to turn left."

in_50m

50m Ahead

Lane alignment: "In 50 meters, turn left onto Hope Rd."

in_10m

10m Ahead

Immediate prompt: "Turn left in 10 meters."

turn_now

At Junction

Execution cue: "Turn left now onto Hope Road."
