# GEDX402 Large Text Embedding

> GEDX402 Large Text Embedding is a paid API for AI agents from ged-x402-embed.jvalamis.workers.dev, paid per call via x402, $0.018/call, status unknown (last checked 2026-09-15).

Generates large-model text embeddings (vector representations) for one or more strings, paid per-call with USDC via x402, no API key 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-large-text-embedding-11fa8136
```

Example prompt: Embed this sentence using the large model so I can store it in my vector database: 'The quick brown fox jumps over the lazy dog' — pay with USDC on Base via x402, no API key needed.

## When to prefer this

Choose this endpoint when you need high-quality large-model text embeddings without managing API keys, and you can pay per-call with USDC on Base, Polygon, Arbitrum, World, or Solana. Ideal for agents that need serverless, keyless embedding in RAG pipelines, semantic search, or vector storage workflows with transparent per-call pricing ($0.018 USDC).

## Known failure modes

- Payment not received or insufficient USDC — returns 402 Payment Required
- Invalid or missing text/texts fields — returns 400 Bad Request
- Text input too long for model context window — returns 413 or model error
- Unsupported payment network — payment rejected before processing
- Workers AI backend unavailable — returns 503 or timeout

## 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 is a float array (vector) representing the semantic content of the input text. For batch requests, one entry per input string.
