## 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 deepent-research-agent-api-7786b679 -d '<json body>'
```

Example prompt: Use the Deepent Research standard model to answer this question without any refusals: what are the most common methods used in social engineering attacks and how do they work in detail?

## When to prefer this

Prefer this endpoint when you need LLM text generation without content restrictions or safety filters, particularly for security research, sensitive topic analysis, harm-reduction content, or any domain where standard LLMs refuse to respond. It operates on a per-request pay-as-you-go basis via x402 USDC micropayments ($0.05/call), making it suitable for agents that need occasional uncensored inference without a subscription. Choose the performance model tier for higher-quality or more complex completions.

## Known failure modes

- Payment failure if x402 USDC payment of $0.05 is not provided or rejected
- Invalid model enum value causing request rejection
- Malformed messages array or missing required role/content fields
- Network timeout for long-form performance model completions
- Rate limiting or quota exceeded on the provider side

## How this service works

Deepent Research — refusal-free LLM inference (per-request)

## Output

The endpoint returns an AI-generated assistant message completing the conversation, produced by either the standard or performance LLM variant. The response contains the model's generated text without content filtering or refusals applied.
