Powering automation across leading teams

OPENBOTDRIFTOPSSCRAPELYFIREDESKBYPASS.IONIMBUS
Built for automation

Everything you need. Nothing you don't.

High-throughput solver

Submit thousands of requests in parallel. The distributed worker cluster auto-scales so latency stays flat under load.

Drop-in API

Already on a competitor? Change one line. Compatible payload schema means existing scripts just keep working.

Auto-tuning fleet

Each worker self-optimizes throughput, retries and backup capacity per domain. No more babysitting configs.

Privacy by default

No solution payload retained, encrypted handshakes, isolated tenant pipelines for critical environments.

Always-warm pool

Solutions are pre-staged so the first call doesn't pay the cold-start tax. Instant pickup at peak hours.

Global redundancy

Multi-region failover with healthchecked nodes. If a region degrades, traffic seamlessly reroutes.

Pay-as-you-go

One simple price. Real-time billing.

No hidden fees, no subscriptions. You only pay for successful solutions, with deductions applied the moment the worker finishes.

FAQ

Questions, answered.

  • We bill per successful solution, deducted from your balance the moment the solver returns a token. Failed or expired requests are not billed.

  • No persistence beyond what's needed to dispatch a solution. Solution tokens are removed shortly after delivery, and we never share data with third parties.

  • Yes. Endpoints, payload schema and response shapes mirror the most common providers, so you can switch with a single base-URL change.

  • Our auto-tuner observes per-domain demand each hour and adjusts internal multipliers automatically — you don't need to tune anything manually.

  • Both. Cryptomus checkout supports USDT, BTC, ETH and more; VietQR transfers credit your account automatically once the bank confirms.
