# Halowerk Terminal Canonical Edit Trace Validator

> Halowerk Terminal Canonical Edit Trace Validator is a paid API for AI agents from detect.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-11-04).

Validates claimed readable byte counts against a synthetic canonical terminal edit trace, verifying consistency of terminal control signals and byte sequences.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability halowerk-terminal-canonical-edit-trace-validator-51bbc01b -d '<json body>'
```

Example prompt: Check whether a claimed readable byte count of 42 is consistent with this canonical terminal edit trace: bytes [65, 10, 8, 65, 10], EOF=4, EOL=0, erase=127, kill=21, with canonical mode enabled (no signals, no extensions), icrnl=true, igncr=false, inlcr=false.

## When to prefer this

Use this endpoint when you need to programmatically verify whether a stated readable byte count is consistent with a canonical terminal (termios) edit trace, particularly in contexts involving terminal emulator testing, security auditing of terminal records, or fuzzing/differential testing of terminal line discipline implementations.

## Known failure modes

- Invalid byte values outside the allowed numeric range cause rejection
- claim value inconsistent with byte array and control characters returns mismatch error
- Missing required fields (bytes, claim, eof, eol, erase, kill, flags) cause 400 validation error
- Byte array exceeding 128 items is rejected
- Payment not provided or insufficient USDC causes 402 response

## How this service works

Prüft behauptete lesbare Bytemengen nach einem synthetischen kanonischen Terminal-Editiertrace.

## Output

Returns a detection or validation result indicating whether the claimed readable byte count is consistent with the provided canonical terminal edit trace, including control character values (EOF, EOL, erase, kill), line-discipline flags (icrnl, igncr, inlcr), and canonical mode settings.
