Most “agent economy” posts sell you a framework, a Discord, or a token.
I wanted the boring thing: a public catalog where an agent can find a tool, call it, and keep a receipt — without me standing in the loop.
That surface is live. It is called AIMarket Hub. The URL is modelmarket.dev. Crypto stays off this title on purpose. The shape here is discover → invoke → receipt.
Counted 2026-09-15 from /ai-market/v2/stats/live:
| Invokes | 710 (704 ok — 99.2%) |
| External / self | 700 / 10 |
| Federated hubs | 14 |
| Capabilities | 177 |
| p50 latency (24h) | 90 ms |
| Revenue / hour | $0.0010 |
That last number is the honesty tax. This is not Uniswap. It is a small live market that already meters calls. The screenshots below are the product, not a mock.
The terminal. EN UI. MCP remote in the same chrome: https://modelmarket.dev/mcp.
The thesis (one sentence)
If your agent stack only works inside a demo transcript, you don't have a market — you have a screenshot.
A market needs supply, demand, a place they meet, a price, and a way to fail out loud. The Hub is that place. Frameworks are how you talk to it.
We already wrote the 15-minute “list your own HTTP tool” walkthrough (publish-and-earn) and the two-tool MCP door (Hub MCP). This piece is narrower: open the live terminal and read what it is actually doing.
The grammar
-
Discover. Type a job in English. Federation returns capability ids, prices,
source_hub. - Invoke. One POST. Hub 402 / failed call → the UI shows the failure. No canned weather.
- Receipt. Metered, signed, re-checkable. You do not have to trust the narrator.
HTTP 402 is a product feature, not an error page: Channel → Invoke → Receipt → Settle. Settlement exists (USDC on Base, small demo funds). You do not need a wallet to watch the feed or run a free trial.
What the feed is actually calling
EXT = someone else paid. One weather row at 475 ms is free and red — fail loud, not a painted success.
When I loaded the page, the tape was not a synthetic demo reel. It was:
| capability | hub | price | latency |
|---|---|---|---|
gaia.weather.read@v1 |
iot.modelmarket.dev | $0.001 | ~80–97 ms |
sortes.draw@v1 |
oracles family | $0.006 | 18 ms |
murmuration.aggregate@v1 |
oracles family | $0.002 | 48 ms |
Weather dominates. That is honest demand, not a balanced pie chart. Sortes is the verifiable-draw capability other live surfaces actually spend. This article is not those products. One failed weather call sits in the same list as the successes. Pretty dashboards that hide the red row are cosplay.
The decoder strip above the table is the same grammar: capability_id → route [LOCAL/FED] → traffic [EXT/SELF] → $ → ms → ✓/✗.
Type a job. Don't browse a PDF.
Match, not autocomplete theatre. Prices and “click to try free” on the same card.
I typed fair randomness for a lottery. Back came, among others:
-
sortes.verify@v1— verify an ECVRF proof offline · $0.00101 · 10 ms -
platon.beacon@v1— hash-chained randomness beacon · $0.00404 · 10 ms -
platon.random@v1— signed chaos-VRF · $0.00404 · 13 ms
Search is a catalogue. It is not a lottery. Read the description before you spend a trial. The Hub already has a free-trial path (a handful of invokes per visitor per hour) so you can feel a receipt before any wallet.
Same box accepts other intents the landing already suggests: wildfire brief near a facility, protect a ship from navigation spoofing. Those are live SKUs with their own honesty footnotes. This article does not tour them.
How to talk to it (without the monorepo)
Three doors. Pick one. Do not install seventeen servers.
| Door | What it is |
|---|---|
| Terminal | modelmarket.dev — search, try, watch the feed |
| MCP |
https://modelmarket.dev/mcp — two tools: market_search, market_invoke
|
| CLI |
pip install aimarket-hub — publish your own capability |
If you want agents inside LangGraph/CrewAI to see the catalogue as native tools, that is a two-line bridge. If you want to list an endpoint you already have, that is the 15-minute article. This page is the room those posts assume is real.
What I am not claiming
- Not TVL. $0.001/hour is the live meter. Small funds, small market.
- Not 10,000 agents. 710 invokes, 14 peers, 177 federated capabilities. Counted from JSON, not a pitch deck.
- Not a token. No airdrop, no points market. 402 is HTTP.
- Not the factory. AICOM ships pages. The Hub is where tools get used. Mixing both in one post converts nobody — we already made that mistake in our heads, so this article does not.
Production listing still has gates (publish token, signed provider responses, supply-security). Start on the public terminal or a local hub. Don't paste a localhost invoke_url at prod and act surprised.
Open it
- modelmarket.dev — type a job, watch one row land in the feed.
- Stats (the numbers above): stats/live
- Code: github.com/alexar76/aimarket-hub (MIT)
If a market that fails loud and keeps receipts is your kind of boring, a ⭐ on the hub repo helps other people find the example. Concrete issues help more than a polite “cool stack.”
Built in the open. The screenshots are the product, not a mock. Numbers from 2026-09-15.
