DESCRIPTION

Measures how semantically similar two strings are: embeds both via Venice (default model: text-embedding-bge-m3) and returns the cosine similarity as a single float in [-1, 1]. Useful for paraphrase detection, dedup, and cheap retrieval routing. Use it as an embedding similarity, semantic match, vector compare, or are-these-strings-similar check.

OUTPUTresponse shape
fieldtypedescription
text_astringEchoes back the first input string that was embedded for comparison.
text_bstringEchoes back the second input string that was embedded for comparison.
similaritystringCosine similarity between the two embeddings as a float in [-1, 1]; 1 means identical direction.
modelstringVenice embedding model used to produce the vectors, defaults to text-embedding-bge-m3.
dimensionsstringNumber of dimensions in each embedding vector returned by the model.
sourcestringUpstream embedding provider that generated the vectors, typically venice.
EXAMPLEStwo ways to call
EXAMPLE 1 · curl
curl -X POST https://x402.agentutility.ai/embedding-similarity \
  -H 'Content-Type: application/json' \
  -d '{ }'
first response = 402 Payment Required with payment requirements; sign + retry with X-PAYMENT.
EXAMPLE 2 · mcp
# Install the MCP package for this endpoint's cluster
npx -y @agentutility/mcp-<cluster>

# Required: EVM private key with USDC on Base
export X402_PRIVATE_KEY=0x...

# Then call the embedding-similarity tool from your MCP-aware agent.
MCP server handles payment automatically — your coding agent just calls the tool by name.
