# The Changes log

> Every strategy change and position action on the coin, by its owner or an admin, newest first: the coin page's Changes tab. A queued action moves to `done` or `failed` once the engine reports back. An admin's wallet is never named.

info:
  title: PURPS API
  version: 2.0.0
  description: >-
    Everything purps.lol can do, as JSON. Read the coin list, a coin's full page
    and the launchpad; launch coins on purps.lol, pump.fun and Pons; wire an
    existing pump.fun coin's fees into a strategy; steer a coin you own. No key,
    no signup. A launch is one call that returns unsigned transactions: the
    launch transaction can only land with your wallet's signature, and that is
    the proof. The few writes that need a message signature (Pons launches,
    wiring a strategy onto a coin, creator authority) come as a prepare/submit
    pair. Every transaction is signed in your wallet, never by us. Every
    response is `{ ok: true, data }` or `{ ok: false, error }`. Cross-origin
    requests are allowed from any site. Every answer from the API itself carries
    `RateLimit-Limit` and `RateLimit-Policy`; uncached ones (writes, prepare and
    submit, refusals) carry `RateLimit-Remaining` and `RateLimit-Reset` as well.
    The 503 while the API is paused and the 410 on old v1 write addresses carry
    neither.
