## When to prefer this

Choose this endpoint when you need a low-cost, pay-per-call T9 alphanumeric encoding of text strings, especially within autonomous agent pipelines that use x402 micropayments on Base. Ideal for legacy telephony, SMS routing, keypad-based input systems, or any workflow requiring T9 tokenization without a self-hosted solution.

## Known failure modes

- Text exceeds 50,000 character limit — request rejected
- Empty or missing 'text' field — validation error
- Payment failure via x402 on Base — 402 response, no result returned
- Malformed JSON body — 400 error
- Non-alphanumeric characters in input may be dropped or cause unexpected encoding results

## How this service works

Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
