# PayWeave Replicate – Real-ESRGAN Image Upscaler

> PayWeave Replicate – Real-ESRGAN Image Upscaler is a paid API for AI agents from replicate.payweave.services, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14, last successful call 2026-07-25).

Upscales and enhances images using the Real-ESRGAN model via PayWeave's pay-per-call Replicate proxy

## Facts

- Endpoint: POST https://replicate.payweave.services/models/nightmareai/real-esrgan/predictions
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Last successful call: 2026-07-25
- Success rate: 100% of calls made through Zero
- Activations on Zero: 1
- Tags: x402
- Canonical page: https://www.zero.xyz/c/payweave-replicate-real-esrgan-image-upscaler-5a0583b8
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_WalWfmLqVMmH7ibklERSy

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-real-esrgan-image-upscaler-5a0583b8 -d '<json body>'
```

Example prompt: Upscale this blurry product photo to 4x its original size using Real-ESRGAN so it looks sharp and print-ready: https://example.com/product-thumb.jpg

## When to prefer this

Choose this endpoint when you need AI-powered image super-resolution or upscaling using the well-known Real-ESRGAN model, especially when you want pay-per-call pricing via crypto (USDC) without a Replicate subscription. Ideal for single-image enhancement tasks in automated pipelines where no recurring API key management is desired.

## Known failure modes

- Image URL is inaccessible or returns a non-image response — prediction fails with error message
- Input image format unsupported by Real-ESRGAN — returns status 'failed' with error description
- Payment failure (insufficient USDC balance) — 402 response before prediction starts
- Model times out on very large images — status 'failed' or 'canceled'
- Output CDN URL expires after ~24 hours — downstream use must cache promptly

## How this service works

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

## Output

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