How this service works
Machine-payable document & media generation via x402 (USDC on Base). Endpoints respond 402 with payment instructions; retry with an x402 payment header.
Output
Returns an SVG (image/svg+xml) or PNG (image/png) chart image rendered from the provided data. The format depends on the output parameter: omit for SVG or set output=png for PNG.
Example use cases
Example prompt
“Generate a bar chart showing monthly sales — January $12,000, February $15,500, March $9,800 — and give it to me as a PNG image.”
Technical details
Endpoint
POSThttps://docforge-selim.duckdns.org/chartWhen to prefer
Use this endpoint when you need to programmatically generate chart images (SVG or PNG) on a pay-per-use basis with USDC micropayments via x402, without requiring an API key subscription. Ideal for agents that need occasional chart generation billed per call rather than a flat subscription.
Side effects
- 402 Payment Required if x402 payment header is missing or invalid — must retry with a valid USDC on Base payment header
- Invalid or malformed chart data causing a 400 Bad Request
- Unsupported chart type resulting in an error response
- Network or service unavailability from the dynamic DNS host (duckdns.org) causing timeouts
