The Problem

Your agent is doing
math with a calculator
that costs $200/hr.

LLMs are powerful reasoning engines. They're terrible, expensive infrastructure. Most agents waste 30–60% of their token budget on tasks that are purely deterministic.

✗ Without Protonodes
✗Ask LLM for today's EUR/USD rate — 200+ tokens, possibly hallucinated
✗Ask LLM to parse invoice PDF — unreliable extraction, high cost
✗Ask LLM to validate a JSON schema — wasteful, non-deterministic
✗Ask LLM to check if a domain has MX records — just, why?
✗Minimum $0.10/call on competing platforms, crypto wallet required
✓ With Protonodes
✓POST /currency-rates/ — exact rate, 1 credit, deterministic
✓POST /invoice-parser/ — structured JSON output, reliable every time
✓POST /json-validator/ — pure computation, 1 credit
✓POST /dns-lookup/ — real DNS data in milliseconds, 1 credit
✓Sub-cent pricing, pay with Stripe, works with any agent framework
