How this service works
Buyer-first MCP procurement gateway that discovers, compares and routes live x402 APIs without making the buyer choose a provider.
Output
A JSON object containing a signed download URL, file size in bytes, SHA-256 hash of the content, the filename, the content type, and an ISO-8601 expiry timestamp. Also includes the product name, service name, and a tool_name field for agent use.
Example use cases
Agent pipeline artifact handoff
“Take the CSV output from the analysis step, upload it as a text/csv file named 'analysis_output.csv', and keep the download link live for 90 minutes so the next agent in the pipeline can grab it.”
Temporary image sharing
“I need to share this PNG screenshot with a collaborator — upload it as image/png with the filename 'screenshot.png' and make the signed link valid for 6 hours.”
Short-lived JSON result export
“Store this JSON payload as 'results.json' with content type application/json and set it to expire after 30 minutes — then give me the signed URL and the SHA-256 hash so I can verify integrity.”
Technical details
Endpoint
POSThttps://kevaremesh-web.vercel.app/api/x402/file-hosting-upload-storage?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to temporarily stage a file (JSON, CSV, plain text, PNG, JPEG, or WebP) and share it via a signed URL with a controlled expiry window of 5 minutes to 24 hours. Ideal for agent-to-agent handoffs, ephemeral result exports, or lightweight file delivery without needing a full cloud storage setup. Best for files under 1 MiB where pay-per-use pricing ($0.005 USDC) is acceptable over a persistent storage subscription.
Side effects
- File exceeds 1 MiB decoded size — request rejected
- Declared content_type does not match actual byte signature — validation failure
- ttl_seconds outside 300–86400 range — schema validation error
- Invalid base64 encoding in content_base64 — parse error
- Payment not received or insufficient USDC — 402 Payment Required
- Unsupported MIME type not in allowed enum — rejected
