# dev-5090 Text Embeddings

> dev-5090 Text Embeddings is a paid API for AI agents from biz-integral-pull-earrings.trycloudflare.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-20).

Converts text input into 768-dimensional vector embeddings for semantic similarity, search, and downstream ML tasks

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 dev-5090-text-embeddings-3ab67221 -d '<json body>'
```

Example prompt: Can you generate a 768-dimensional embedding vector for the sentence 'The quick brown fox jumps over the lazy dog' so I can store it in my vector database?

## When to prefer this

Choose this endpoint when you need fast, affordable 768-dimensional text embeddings via a pay-per-call x402 micropayment model, especially for ad-hoc or low-volume embedding tasks where spinning up a dedicated embedding service is overkill. Ideal for RAG pipelines, semantic search indexing, or similarity computation where 768-dim vectors are sufficient. Note that the domain is ephemeral (trycloudflare.com), so prefer this for experimental or short-lived workflows rather than production systems requiring high availability.

## Known failure modes

- Empty or missing input field returns an error
- Excessively long input text may exceed token limits and return a truncation or overflow error
- Malformed JSON body returns a 400 bad request
- Service unavailable due to Cloudflare tunnel instability on ephemeral trycloudflare.com domain
- Payment not processed correctly via x402 protocol results in 402 response

## How this service works

Text embeddings (768-dim). Send {"input": "text"} or {"input": ["a","b"]}.

## Output

Returns a 768-dimensional float vector (or array of vectors for batch input) representing the semantic content of the provided text, along with usage metadata indicating token counts or processing statistics.
