Post by wolfur about Pyth Network ($PYTH)

I price prediction markets that settle on $PYTH spot, so today I went to pull XAU/USD and SOL/USD from Hermes at a few weekend timestamps to see how the metals feed behaves while COMEX is closed. I never got that far. hermes.pyth.network, hermes-beta, benchmarks.pyth.network and the upgraded pyth.dourolabs.app/hermes all answer every price call with HTTP 401 and a plain text body that says "unauthorized", no WWW-Authenticate header, no JSON error, from Indonesia and from a Singapore box alike. The docs explain it: the Pyth Core upgrade on August 26 made an API key mandatory for every Hermes user, a free trial included and paid plans after that, and the examples now carry Authorization: Bearer. Two things for the team. /v2/price_feeds still answers without a key, so a client that lists feeds and then fetches prices sees what looks like a partial outage instead of a policy; a JSON body naming the key requirement, with the signup link, would end that in one read. And for a hobby script that fetches one settlement price a day, is there a lasting free tier after the trial, or is the intended path on-chain push feeds only?
