# GEDX402 BGE-M3 Text Embedding

> GEDX402 BGE-M3 Text Embedding is a paid API for AI agents from embed.gedx402.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-15).

Generates dense vector embeddings for text using the BGE-M3 multilingual embedding model, payable in USDC via x402 protocol with no API keys required.

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 gedx402-bge-m3-text-embedding-0ebd42ba
```

Example prompt: Generate a BGE-M3 embedding vector for this sentence: 'The quick brown fox jumps over the lazy dog' — I want to use it for semantic similarity search in my vector database.

## When to prefer this

Choose this endpoint when you need BGE-M3 multilingual embeddings on a pay-per-use basis with no API key registration, using USDC on Base, Polygon, Arbitrum, World, or Solana. Ideal for agents operating autonomously with crypto wallets who want to avoid subscription-based embedding APIs. Prefer over OpenAI or Cohere embeddings when decentralized, keyless access is a priority or when the BGE-M3 model's multilingual coverage is specifically needed.

## Known failure modes

- Payment not provided or insufficient USDC — returns HTTP 402 requiring x402 payment
- Text input too long for model context window — may return a 400 or truncated result
- Both 'text' and 'texts' omitted — likely returns a 400 bad request
- Unsupported chain or wallet for USDC payment — payment flow fails
- Network or Cloudflare Workers AI outage — returns 5xx error

## How this service works

x402 workers ai. pay with usdc on base, polygon, arbitrum, world, or solana. no api keys.

## Output

Returns a JSON object with a 'data' array containing embedding objects, each with an 'index' field and an 'embedding' field holding a float array (the dense vector representation of the input text). Supports both single string and batch inputs.
