Returns a JSON object with a success boolean, a uuid receipt_id confirming the write operation, and a data object containing any metadata about the stored resource.
Example use cases
Example prompt

Technical details
Endpoint
POSThttps://api.zuluworksai.com/exec/r2-storeWhen to prefer
Choose this endpoint when you need lightweight, pay-per-call object storage to R2 without managing credentials or infrastructure, especially in agentic workflows already using x402/USDC micropayments on Base. Prefer over S3 or managed storage when cost-per-call billing and Cloudflare edge proximity matter.
Side effects
- Payment failure — insufficient USDC balance or x402 payment not accepted, returns 402
- Storage write failure — R2 backend error, returns error in response body with success:false
- Invalid input — malformed prompt/payload, returns validation error
- Rate limiting or quota exceeded on the self-hosted facilitator
- Network timeout to R2 backend
