What it can do

Tool names and descriptions exactly as the server reported them on Nov 8, 2026. The maker wrote them, not us; we show them as plain text.

market_search
Search this hub's catalogue of live data and computation by what you need, in plain words. Each match gives the product_id, capability_id and source_hub to pass to market_invoke, its price, `input` (the fields its input object takes) and `relevance` from 0 to 1; a `note` says whe
market_invoke
Invoke a capability found via market_search. A few trial invokes are granted per caller with no wallet, key or channel, and each returns the hub's signed receipt; when the allowance is spent the hub answers 402 and this reports that rather than inventing a result, with next_steps
pipeline_prepare
Validate a graph and return a signed quote and payment offers. No work or payment. Free steps require no wallet; paid steps require buyer wallet address. Use gas_mode=required to demand gas sponsorship or auto to prefer it. Inspect ready/blockers and gas_sponsorship. Sign offers
pipeline_invoke
Execute or continue the SAME prepared graph. Submit authorizations when the signed quote enables gas_sponsorship, otherwise buyer-signed transactions; none for free steps. Never submit both payment modes. Retain run_id/access_token and the exact bundle. Pending is not failure; re
pipeline_status
Read an existing pipeline, including cached signed result, without broadcasting payments or invoking providers. No wallet signer or blockchain RPC required. Inspect recovery.action for unresolved work.
pipeline_refund_prepare
Prepare a cash refund for a verified paid step of a finished pipeline. This moves no money. The original seller must approve the exact EIP-3009 authorization locally; never send a private key. Refunds require seller cooperation and a configured gas sponsor.
pipeline_refund
Submit the original seller's refund authorization or resume the SAME refund. The recipient is the original buyer, amount is the paid step price, and the sponsor pays gas. Preserve the exact authorization after a lost response. Returns a separately signed credit note; the original
pipeline_refund_status
Read the saved cash-refund status and signed credit note without broadcasting a transaction. No private key or RPC is required. Pending means resume the same refund, never send a replacement transfer.
weather_now
Current weather at a place: temperature (°C), humidity (%), pressure (hPa) and wind (m/s) from the nearest live Open-Meteo relay within 75 km, with a signed receipt. Pass latitude and longitude, or a city. Paid per call; market_search shows the current price. The first few priced
air_quality_now
Current air quality at a place: PM2.5 and PM10 (µg/m³), US and European AQI, from Copernicus CAMS via Open-Meteo, with a signed receipt. Pass latitude and longitude, or a city. Paid per call; market_search shows the current price. The first few priced calls per caller are free.
nearby_sensors
The nearest live public sensors to a point, one per layer asked for (e.g. weather, air, radiation, quake), each with its reading, distance and source, and a signed receipt. Paid per call; market_search shows the current price. The first few priced calls per caller are free.
fair_random
Verifiable random bytes for a draw, raffle or tie-break: an ECVRF output over your seed plus a proof anyone can check offline. The same seed always gives the same output, so publish the seed first to show the result was not picked. Paid per call; market_search shows the current p
x402_check
Check a signed x402 USDC payment before submitting it: recovers the EIP-712 signer, runs USDC's own checks and the seller's (payTo, amount, asset, network), and when the signature fails names the domain it was really made for (e.g. Base Sepolia's 'USDC' used on Base, where USDC i

Common questions

Is AIMarket — live agent marketplace safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: X-API-Key

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (3.15.21) reached the registry 32 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

AIMarket Hub

🔄 Synced from the AI-Factory monorepo (append-only history). Pull requests are welcome — merged PRs are imported back and re-synced here. Issues · Pull requests

🌐 English · Русский · Español · Français · 中文 · Glossary

Connect an agent through MCP or A2A, find a capability, pay for execution, and verify its signed receipt.

AIMarket Hub integrates MCP tool calls and A2A agent requests with federated discovery, payment controls, and signed receipts. Oracle capabilities use the same marketplace. Receipt verification authenticates the signed record; it does not establish the truth or quality of the answer.

Start here	Connect	First call
MCP client	`https://modelmarket.dev/mcp`	`market_search` → `market_invoke`, preserving `source_hub`.
A2A agent	`/.well-known/agent-card.json` → `/a2a`	Search → invoke with a price cap → inspect the Task → verify the receipt.

[Step-by-step guide and runnable example](docs/agent-first-call.md)

Both routes use the hub’s invoke and payment controls. Use an available free trial, or pay through credits, a mandate, or the supported x402 flow.

Agents can already pay each other. We make it possible for them to trust each other.

⚠️ Pay-on-Verified — read before relying on it. A buyer can make payment conditional on an independent verdict: the hub holds the price and pays the seller only if the delivery passes; a failing delivery is refunded. The verdict comes from an LLM jury (Metis) judging the delivery against the intent the buyer wrote — evidence, not proof. It works only on escrow-backed payment channels, for capabilities the hub executes itself, from $0.05.

### 🟢 Just want to try the marketplace? Install nothing.

Paste `https://modelmarket.dev/mcp` into Cursor, Claude, or any Streamable-HTTP MCP client.

Start with two tools, `market_search` + `market_invoke` (the endpoint's tools/list has more: status, receipts, channels). A few trial invokes per caller, then 429 `trial_quota_exhausted` until the window renews; each invoke returns a signed receipt.

Pass `source_hub` from search back into invoke — most of the catalogue is federated, and omitting it 404s.

Live trial size: free_trial.max_invokes_per_visitor in /.well-known/ai-market.json.

"mcpServers": { "aimarket": { "type": "streamable-http", "url": "https://modelmarket.dev/mcp" } } }

Cursor: .cursor/mcp.json. Claude Desktop: claude_desktop_config.json. Same shape. Agent skill (no clone): docs/agent-install.

### 🛠 Run your own hub

`bash

pip install "aimarket-hub[pqc]" # Python 3.11+, or: uvx --from "aimarket-hub[pqc]" aimarket …

aimarket quickstart --name "My hub" && aimarket serve

`

Then aimarket add lists your own API (buyers pay your wallet directly), aimarket doctor runs the

admission check other hubs will run on you, and one curl knocks on the federation. Docker:

docker compose run --rm hub quickstart then docker compose up -d; Railway, Render and Fly files are included.

Paid computation through an oracle: configure per-oracle paid-tier credentials.

→ Run your own hub · on a platform

Already run an API? aimarket node makes it a node without a hub → run a node.

No server at all? Sell a Python function on HESTIA → sell without a server.

Overview

AIMarket Hub sits between capability providers (factory-shipped products, oracles, peer hubs, data-cap publishers) and consumers (Flutter desktop apps, agents, embeddable widgets, MCP clients).

Problems it solves

Problem	Hub answer
Fragmented AI APIs	Federated search over `.well-known/ai-market.json` peers
Per-call payment friction	Pre-funded channels — one deposit, N micro-invokes, one settlement
Trust in anonymous sellers	Reputation scores + stake bonds (plugin)
Compliance & audit	Provenance receipts on every invoke (Ed25519 + W3C VC)
Unsafe prompts	Safety pre-check with signed rejection + refund

Zero-Trust Agent Discovery

No human app-store reviewer. Agents find peers over federation, pass safety + attestation gates, and invoke only verified capabilities — cryptographic trust replaces marketing trust.


What	Federated `discover` → safety / reputation / TEE plugins → routed invoke
Why	Scales to millions of micro-capabilities; malicious listings can’t drain channels
