v0.0.1 Marketplace Agent

I have daily cron job with Hermes that uses browser tools to browes second hands deals in my area, super helpful and I have all my friends using it.

Not sure if it fits the tracks, but a fun thing i use hermes for!

Hermes finds me second-hand tech deals daily by using browser tools!

"yo hermes, can you start tracking RAM sticks for me"

So do you have a backend or something?

database?

[grizzled mason]

There is no backend!

its literally hermes-as-backend 😂

hermes will trigger on cronjob -> use brows tools to find deals from a set of vendor links -> curate a json of products, update sqlite on repo -> github pages renders the sqlite

However, i am thinking of also trying out this skill: https://github.com/browser-use/browser-harness

and potentially refactor the "create json update sqlite part"

I am also thinking of having hermes reach out to people for me and try to haggle price

[gentle delta]

any chance of you ever sharing the source-code for personal use?

[grizzled mason]

Ofcourse, i just need to go through the skill files and polish some corners. I also need a bit of deeper understanding on how its getting the data, since now its just "hermes doing it", thats why i wnated to look at the browser-harness skill

also locations and provider urls are kind of hardcoded in the skill, so i need some sort of onboarding or letting hermes figure it out instead of me telling it

[kindred glacier]

love ya!

[kindred glacier]

can u tag me if you share it plez? 🙂

[glass zodiac]

very nice - would this be able to scan facebook marketplace? or ebay kleinanzeigen?

[grizzled mason]

Hermes can adapt to any website, the only thing you need to think about is cookies since Facebook requires a login

[glass zodiac]

did you manage to solve for facebook marketplace? - can hermes use existing FB cookies?

[grizzled mason]

Hermes can use existing cookies to login with fb market I’m 99% sure, it’s just not setup in the skill right now. I don’t have a Facebook account but I can create one for to test with this!

[glass zodiac]

Yup go for it. I think it would be a real plus if FB marketplace worked.

[grizzled mason]

Good to know 👍🏽

[midnight estuary]

Can u tag me once u finish ?

[glad pawn]

this is something i'm planning to build too. I'm thinking about telling hermes my goals/projects/struggles, and at night it tries to plan/design those projects and also find some good deals accordingly, for example:

• I tell Hermes I want to use ZFS on my server, but I might need more RAM, so it goes at night into ebay, FB marketplace, etc. And the next day i get:
  "Hey I found this DDR4 ECC 16GB ram sticks for 120. With four of these sticks, you could run ZFS on your server"

[grizzled mason]

thats so cool, you wanna collaborate? ive been stuck on some issues here and there

[glad pawn]

cool, i would love to! even though i'm very new to all this stuff.
I've also heard about browser-harness and i think it might probably be the best option.

[grizzled mason]

Thats what im using right now, im just having trouple packaging the whole thing as a skill / plugin so it can becaome reusable

[violet fox]

Can this work on the sales side? If you have a ton of stuff you constantly get your hands on and want to have Hermes pull from a photo file when new stuff shows up in it and either prompts you to set a price or finds prices and sets and posts them for you?

[gentle delta]

u tried ever running a cdp browser on your pc and let hermes use it via tailscale?

[grizzled mason]

I was thinking of this also! I’m moving out from my apartment soon and I would love to just take a picture of a produkt, and have hemres post it on second hand sites for me

Possibly even talk with customers for me

[violet fox]

My bro runs a junk removal company and acquires a ton of nice stuff but it’s too much to manually sell. This would be great

[grizzled mason]

Not sure what that is, I used browser-harness and Hermes default browser skills

[fiery ginkgo]

What do you scan @grizzled mason ?
Blocket and tradera?

I am looking for GPUs as we speak so very interested.

[grizzled mason]

Yes blocker and traders, planning on adding fb marketplace I just been having a lot that needs wrapping up at work and school so haven’t been getting around to it

Im looking for gpus also!

I have a question guys.

What would be the optimal installation guide? I’m thinking a repo with a single prompt that can be given to Hermes. However each persons setup would be so different

Different vendors, different items, different cron job timing

So I’m thinking a Python setup.py that asks all these question, creates a personal_config.md or something that gets fed to Hermes + a setup.md?

[gentle delta]

damn, browser harness for me never was enough to fight anti bot detections like cloudflare...

[gentle delta]

repo with 1 short prompt that guides Hermes to read an .md file that includes the whole installation guide for him

[grizzled mason]

im trying my best to get a repo out with an OK boilerplate that can get us all here started so we can work together on solvign this issue

[grizzled mason]

thats exacly what im trying to get rightnow, have gpt 5.5 on it

[small sparrow]

browserbase + firecrawl via api key

trust

[grizzled mason]

👀

[glad pawn]

i've also heard of Obscura and Lightpanda. not sure how both of these compare

[mellow nacelle]

tag me too. bump

[gentle delta]

aint that paid?

[small sparrow]

they r generous w free credits upon first sign up

[small sparrow]

ive heard obscura is bad for more complex websites, lightpanda might be okay

[grizzled mason]

ok guys I wont have more time to work on this today, ive tried my best to package my local implemntation into a shareable github repo, the repo is still obviously not finished, if someone is looking to hack around and try it please do so, i really need the feedback. ill have time to look at issues tomrrow and even put some hours in to polish

heres the repo: https://github.com/Matars/marketplace-agent

open for contributors

IMPORTANT:

1. there is no frontend that parses the output json data of found marketplace products (easy fix)
2. I have only tested finding products and not sell / posting / listing (i dont think this workflow is finished)
3. might fall back to using hermes ntaive browser tools and not the scrapers (ex. amazon might block bots as stated in this thread), which might lead to high token usage so keep an eye on this when starting out. pretty sure hermes will prompt you to usee browser-harness to fix 0 results on scrapers
