# PayWeave Replicate — Stable Diffusion 3.5 Large Image Generation

> PayWeave Replicate — Stable Diffusion 3.5 Large Image Generation is a paid API for AI agents from replicate.payweave.services, paid per call via x402, $0.13/call, status unknown (last checked 2026-09-15).

Generates high-quality images from text prompts using Stability AI's Stable Diffusion 3.5 Large model via a pay-per-call API

## Facts

- Endpoint: POST https://replicate.payweave.services/models/stability-ai/stable-diffusion-3.5-large/predictions
- Price: $0.13/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/payweave-replicate-stable-diffusion-3-5-large-image-generation-299507df
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_UAh7AmeytxtZ0yG1XKwP2

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 payweave-replicate-stable-diffusion-3-5-large-image-generation-299507df -d '<json body>'
```

Example prompt: Generate an image of a serene Japanese garden at sunrise with cherry blossoms and a koi pond — I want photorealistic quality with warm golden lighting.

## When to prefer this

Use this endpoint when you need to generate images using Stability AI's Stable Diffusion 3.5 Large model specifically, and want pay-per-call pricing via USDC with no subscription required. Prefer this over managed API subscriptions when building agents that need on-demand image generation billed per inference. The x402 payment protocol makes it suitable for autonomous agents that can pay per call without pre-arranged credentials.

## Known failure modes

- Invalid or missing input object returns an error status with error message
- Model inference failure returns status='failed' with error description
- Image CDN URL expires after ~24 hours making the output inaccessible
- Payment failure (insufficient USDC balance) prevents the call from executing
- Request timeout if model is cold-starting or overloaded, returning status='starting' or 'processing' indefinitely
- Malformed prompt or unsupported parameters may return a failed prediction

## How this service works

Run open-source AI models — image, video, audio.

## Output

Returns a prediction object containing a Replicate prediction ID, the model name, a status field (succeeded/failed/canceled/processing/starting), a CDN-hosted image URL valid for ~24 hours, timing metrics (total_time, predict_time), timestamps, and the USD amount charged for this call.
