POST /v1/chart

live

Data to chart in one call: a numeric series rendered as a deterministic 800x400 line or bar chart SVG with optional labels and title. No charting library, no browser — an agent composing a report gets a predictable picture of its numbers.

Verdict: live. The unpaid GET reached a valid 402. The live amount equals the catalog price.

The catalog declares POST. A 402 answer carries the payment requirements in the JSON body and, for x402 v2, base64 in the PAYMENT-REQUIRED header. This page never sends a payment.
