# GEDX402 PLaMo Embedding 1B

> GEDX402 PLaMo Embedding 1B is a paid API for AI agents from ged-x402-embed.jvalamis.workers.dev, paid per call via x402, $0.0035/call, status unknown (last checked 2026-09-14).

Generates vector embeddings for text using the PLaMo-Embedding-1B model, paid per-call with USDC via x402 protocol on multiple blockchains

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-plamo-embedding-1b-ba9ed9a1
```

Example prompt: Embed this sentence for me so I can do a similarity search: 'The quick brown fox jumps over the lazy dog' — use the PLaMo embedding model and pay with USDC.

## When to prefer this

Choose this endpoint when you need text embeddings without setting up API keys or accounts — ideal for AI agents that can pay USDC micropayments via x402 on Base, Polygon, Arbitrum, World, or Solana. Particularly useful for RAG pipelines, semantic search, or vector database ingestion where permissionless pay-per-use billing is preferred over subscription APIs.

## Known failure modes

- Payment not sent or insufficient USDC — returns HTTP 402 requiring payment
- Text input exceeds model's context window — returns error about input length
- Invalid JSON body or missing both 'text' and 'texts' fields — returns 400 bad request
- Blockchain network congestion causing payment verification delay — timeout or retry needed
- Unsupported chain used 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 with a 'data' array containing objects with 'index' and 'embedding' fields — the embedding is a float array representing the semantic vector of the input text. For batch inputs, multiple embedding objects are returned, each indexed by position.
