How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
Returns a JSON object containing the tier number (4) and a tier-dependent encoded result string derived from the input text.
Example use cases
Agent pipeline data encoding
“Take this raw text output from my agent — 'Order confirmed: item SKU-8821, qty 3, warehouse B' — and encode it using the tier-4 encoding pack so it can be passed to the next stage.”
Compact encoding for storage
“I have a string I need to pack down using tier-4 encoding before storing it: 'user_id=4821&session=abc123×tamp=1720000000'. Can you run it through the t4 encoding pack?”
Encoding test for format validation
“Run this sample text through tier-4 encoding to see what the output format looks like: 'The quick brown fox jumps over the lazy dog.'”
