200 pay-per-call tools for AI agents, from $0.001 per request in USDC on Base or Solana with x402. No account, no API key.
Output

Endpoint
GEThttps://fastx402.tools/workdays-between?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need accurate business day counts for a specific country, including public holiday awareness, without managing your own holiday database. Ideal for deadline calculations, scheduling, SLA monitoring, and financial workflows where country-specific non-working days matter. It requires no account or API key — only USDC payment via x402 on Base or Solana.
Side effects
- Invalid date format (not YYYY-MM-DD) returns an error
- Unsupported or unrecognized 2-letter country code returns an error
- End date before start date may return 0 or an error
- Payment not processed due to insufficient USDC balance causes a 402 response
- Network timeout on slow connections
