Output

Returns an array of chunk objects each containing the chunk text, a zero-based index, SHA-256 hash, unique chunk_id, and start/end character offsets, plus a total chunk_count and source_sha256 hash of the original input.

Example use cases

Example prompt

“Chunk this document into segments for my embedding pipeline and give me SHA-256 hashes for each piece so I can verify integrity later: 'Our refund policy allows returns within 30 days. Please email support@company.com or call 1-800-555-0100. For bulk orders visit enterprise.company.com.'”

When to prefer

Choose this endpoint when you need text chunking with built-in cryptographic provenance (SHA-256 per chunk and for the source), especially inside an agent pipeline that requires verifiable, tamper-evident chunk receipts. Prefer over generic chunking libraries when you want a paid, trust-gated microservice with Boundary Receipt semantics and interoperability with other Boundary Guard infrastructure (risk scan, PII redaction, schema normalization).

Side effects

Empty or missing 'text' field returns validation error
Extremely large payloads may time out on the Render free tier
x402 payment failure results in 402 response before processing
Malformed JSON body returns 400 error
Network latency spikes on cold-start if Render instance has spun down
