# GEDX402 Text Embedding API

> GEDX402 Text Embedding API is a paid API for AI agents from ged-x402-embed.jvalamis.workers.dev, paid per call via x402, $0.0073/call, status unknown (last checked 2026-09-15).

Generates vector embeddings for one or more text strings using Cloudflare Workers AI, payable with USDC on multiple blockchains via x402 protocol

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-text-embedding-api-ef42e9f9
```

Example prompt: Generate a vector embedding for this text: 'The quick brown fox jumps over the lazy dog' — I want to use it for semantic similarity search, and I'll pay with USDC on Base.

## When to prefer this

Choose this endpoint when you need text embeddings without registering for an API key and want to pay per-call with USDC on Base, Polygon, Arbitrum, World, or Solana. Ideal for agents operating in crypto-native environments or when avoiding traditional API key management is a priority. Useful for one-off embedding tasks or when integrating into x402-compatible payment workflows.

## Known failure modes

- Payment not received or insufficient USDC balance returns 402
- Unsupported blockchain network specified returns error
- Empty or missing 'text' and 'texts' fields returns validation error
- Text input exceeding model context length returns truncation or error
- Network timeout on Cloudflare Workers edge returns 503

## 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 has an 'index' and an 'embedding' field — a float array representing the vector embedding of the corresponding input text string.
