# x402 Agent Economy Lab – Bulk Text Embedding API

> x402 Agent Economy Lab – Bulk Text Embedding API is a paid API for AI agents from rqjzcd-ip-209-115-177-214.tunnelmole.net, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-15).

Generates vector embeddings for multiple texts in a single call, paid per call in real USDC on Base mainnet via the x402 payment 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 x402-agent-economy-lab-bulk-text-embedding-api-3fa0ddad -d '<json body>'
```

Example prompt: Embed these 10 product descriptions in bulk so I can store them in my vector database for semantic search: [list of texts].

## When to prefer this

Choose this endpoint when you need to embed multiple texts in a single paid API call using the x402 micropayment protocol on Base mainnet, particularly in autonomous agent workflows that need machine-payable NLP services without traditional API key auth. Best for pipelines already integrated with x402 USDC payment rails.

## Known failure modes

- Payment failure if wallet has insufficient USDC on Base mainnet — returns 402 Payment Required
- Empty or missing text field returns 400 Bad Request
- Oversized batch may trigger timeout or rate limiting
- Tunnelmole tunnel may be offline, returning connection errors
- Malformed JSON input returns 422 Unprocessable Entity

## How this service works

Machine-payable NLP micro-services: sentiment, entity extraction, summarization, report, batch. Paid per call in REAL USDC on Base mainnet.

## Output

Returns an array of dense vector embeddings, one per input text, suitable for use in semantic search, similarity comparison, clustering, or storage in a vector database.
