Agentshelf Byte Trigram Counter
x402
Agentshelf Byte Trigram Counter is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-02).
Counts byte 3-grams (all distinct 3-byte sequences and their frequencies) in a given text string, with no network calls or LLM involvement.

How this service works
Call when an agent needs counts of byte 3-grams. No network and no LLM. Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/ngram-byte-3 first.
Output
A map or list of all distinct 3-byte sequences found in the input text along with their occurrence counts, covering the full byte-level trigram frequency distribution of the input string.
Example use cases
Byte trigram fingerprinting for language detection
“Compute the byte 3-gram counts for this sample text so I can build a language fingerprint: 'Bonjour tout le monde, comment allez-vous aujourd'hui?'”
Anomaly detection in log strings
“Give me the byte trigram frequency distribution for this log entry so I can check if it matches known patterns: 'ERROR 2024-01-15 kernel: segfault at 00007fff5fbff8a0'”
Text similarity preprocessing
“I need the byte-level 3-gram counts for the string 'machine learning enables computers to learn from data' so I can compute similarity scores against other documents.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/ngram-byte-3?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need exact, deterministic byte-level 3-gram counts without relying on any external network calls or LLM inference. Prefer this over character n-gram or word n-gram services when byte-level analysis is required (e.g., language identification, compression analysis, binary fingerprinting). Always try the free sandbox variant /v1/sandbox/ngram-byte-3 first to validate your input before paying.
Side effects
- Empty or missing text field returns validation error
- Text exceeding 100,000 characters is rejected
- Non-UTF-8 or binary-unsafe input may produce unexpected byte sequences
- Payment of exactly $0.005 USDC required; incorrect payment amount results in 402 error
- Sandbox endpoint /v1/sandbox/ngram-byte-3 should be tried first to avoid unnecessary charges
