# GEDX402 Qwen3 Text Embedding (0.6B) via x402

> GEDX402 Qwen3 Text Embedding (0.6B) via x402 is a paid API for AI agents from ged-x402-embed.jvalamis.workers.dev, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-14).

Generates vector embeddings for one or more text strings using the Qwen3-Embedding-0.6B model, paid per-call with USDC via x402 protocol — no API key required.

## 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-qwen3-text-embedding-0-6b-via-x402-9acc8d9e
```

Example prompt: Convert this sentence into a vector embedding using Qwen3: 'The quick brown fox jumps over the lazy dog' — I want to pay per call with USDC on Base, no API key.

## When to prefer this

Choose this endpoint when you need text embeddings on-demand without managing API keys or subscriptions, and you can pay per call in USDC via the x402 protocol on Base, Polygon, Arbitrum, World, or Solana. Ideal for agents in crypto-native environments, privacy-conscious pipelines, or serverless RAG workflows where credential management is a burden.

## Known failure modes

- Payment not received or insufficient USDC — returns HTTP 402 Payment Required
- Invalid or non-UTF-8 text input — may return 400 Bad Request
- Batch too large — may hit token or size limits
- Network timeout on Cloudflare Workers edge — transient 5xx error
- Unsupported blockchain network for payment — payment rejected

## How this service works

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

## Output

A JSON object containing a 'data' array where each element includes an 'index' and an 'embedding' field — the embedding being a float array representing the semantic vector of the input text. Supports single string or batch inputs.
