One key for every Profullstack service

We run 54 properties. Until today, an agent that wanted to use more than one of them had to deal with each one on its own terms: a day pass here, a rate limit there, a 402 on the next. That is fine for a crawler reading one site. It is a chore for anyone building on the whole fleet.

So there is now one key. A Power Key is a single API key that opens every Profullstack service. Send it as Authorization: Bearer pfs_... or in an x-power-key header and the crawler paywall, the free-tier metering and the per-site passes are gone, on rssamplifier.com, nichedb.dev, coinpayportal.com, crawlproof.com, ugig.net, tipoffwatch.com and the other 48. It also covers anything we launch from now on.

How it works

The key is an Ed25519-signed token. Every site verifies it with the public key that ships in the @profullstack/keys package, offline, so there is no central server on the request path and nothing to be slow or down. There is no account and no dashboard. The key is the whole product.

The gateway that fronts our sites, @profullstack/x402-gateway, treats a valid key as a paid pass from version 0.7.0, and the throttle skips it for the same reason. A site honours the key the moment it updates the package. No configuration, because the public key is already in it.

If you run the gateway on a site that is not ours, pass powerKeys: false, or your own key list and mint keys of your own with the same package.

What it costs

A lifetime Power Key is $299, once. No subscription and no renewal. For the launch, the code 50OFF takes half off, so it is $149.50 while the code lasts.

Pay by card or crypto through CoinPay: USDC on Polygon, Ethereum or Solana, ETH, BTC or SOL, straight to our wallet. The key shows on the confirmation page and lands in your inbox.

Agents can read the shop as data at profullstack.com/shop.json, and every 402 across the fleet now says where to buy one.
