NAME
content-simhash — simhash / 64-bit content fingerprint / near-duplicate detection / dedup hashing / locality-sensitive hash
SYNOPSIS

Content-Type: application/json
X-PAYMENT: <signed-transferWithAuthorization>

402 Payment Required. Sign USDCtransferWithAuthorization, retry with theX-PAYMENT header.DESCRIPTION
SimHash / 64-bit content fingerprint / near-duplicate detection / dedup hashing / locality-sensitive hash. Pure-local 64-bit SimHash over token-level k-shingles (default k=3) using FNV-1a. Two SimHashes are 'close' (small Hamming distance) iff the underlying texts share many shingles. Returns hex + decimal forms plus token + shingle counts. Useful for content dedup pipelines, plagiarism detection, and bot-content clustering.
INPUT — request schema
| property | type | description | req? |
|---|---|---|---|
| text | string | Text to hash. Up to 500,000 chars. | required |
| shingle_size | number | k-gram size for shingles. Range [1, 8]. Default 3. | optional |
OUTPUT — response shape
| field | type | description |
|---|---|---|
| hash_hex | string | 64-bit SimHash fingerprint as a 16-character lowercase hex string. |
| hash_int | string | Same 64-bit SimHash rendered as a decimal integer string (safe for languages without u64). |
| bit_count | string | Number of set bits (popcount) in the SimHash, useful as a quick sanity check. |
| token_count | string | Number of tokens extracted from the input text before shingling. |
| shingle_count | string | Number of distinct k-shingles hashed into the SimHash. |
| shingle_size | string | Shingle width k used (tokens per shingle), default 3. |
| text_chars | string | Character length of the input text that was hashed. |
| source | string | Echoes how the text was supplied (e.g. inline text vs fetched URL). |
EXAMPLES — two ways to call
EXAMPLE 1 · curl
curl -X POST https://x402.agentutility.ai/content-simhash \
-H 'Content-Type: application/json' \
-d '{ }'first response =

# MCP packages on npm under # @agentutility/mcp-* (one per cluster) # # Catalog + install: # https://mcp.agentutility.ai # # Or call content-simhash directly over HTTP — see above.
MCP server handles payment automatically — your coding agent just calls the tool by name.
