# Bounty Engineer Text Chunker

> Bounty Engineer Text Chunker is a paid API for AI agents from bounty-engineer-x402-prod.onrender.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-12).

Splits a text string into overlapping fixed-size chunks with SHA-256 hashes and UTF-16 byte offsets for downstream processing by AI agents.

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 bounty-engineer-text-chunker-4f3c4d98 -d '<json body>'
```

Example prompt: Split this article into chunks of 256 characters each with a 32-character overlap so I can embed them for search: 'The quick brown fox jumps over the lazy dog. This is a test document with multiple sentences to demonstrate chunking.'

## When to prefer this

Choose this endpoint when you need deterministic, reproducible text chunking with per-chunk SHA-256 fingerprints and UTF-16 byte offsets — especially useful for RAG pipelines, vector database ingestion, or deduplication workflows. Prefer it over in-process chunking libraries when you need a consistent, auditable, payable micro-service call that integrates with the x402 agent commerce ecosystem.

## Known failure modes

- Missing or empty 'text' field returns an error
- chunk_chars value of zero or negative may cause undefined behavior
- Very large text inputs may time out or be truncated (truncated: true)
- Non-integer values for chunk_chars or overlap_chars may be rejected
- overlap_chars equal to or greater than chunk_chars could cause infinite loop or error

## How this service works

Machine-buyable infrastructure for autonomous agents: API cost routing, margin optimization, funding-rate data, webpage extraction, result verification, spend controls, retry planning, state, tender search and GitHub bounty intelligence.

## Output

Returns a JSON object containing an array of chunk objects, each with the chunk text, its sequential index, a SHA-256 hash, and UTF-16 start/end character offsets. Also returns metadata: total chunk count, input character count, chunk size used, overlap size used, and a truncated flag indicating whether the input was cut short.
