Open launchpad data

Everything the MemeFees engine stores is available as JSON and CSV over plain HTTPS, no key, no rate card. The store holds 8,652 pad-days of daily series since 2024-03-01, 202,277 counted launches, 659 graduations with follow-ups, and 981 bonding-curve samples across 773 notable tokens. Fees, revenue and volume come from DefiLlama and are labelled by source in every row; everything else is counted by MemeFees. License: CC BY 4.0.

rules of use

Attribute MemeFees with a link to memefees.com wherever the numbers appear (CC BY 4.0).
Keep the source labels: fees, revenue and volume are DefiLlama series; launches, graduations and survival are MemeFees counts.
Respect completeness flags. A day marked incomplete is a floor, not an estimate.
Definitions live on the methodology page and change only with a dated changelog entry.
Bulk mirrors and embeds are welcome; a link back is all we ask.
