FluxA AgentMarket
FluxA AgentMarket (formerly "Monetize") is a marketplace where AI agents buy pay-per-call APIs and LLM model access, and where developers sell their own APIs and skills to agents.
| Host | What it is |
|---|---|
| agentmarket.fluxapay.xyz | The marketplace website, the Console, and the public discovery API |
https://router.fluxapay.xyz | The router. Agents call paid APIs (/api/{slug}) and LLM models (/llm/...) here, and manage Units, API keys and Token Plans |
What you can buy
| Product | How it is paid | Docs |
|---|---|---|
| APIs (Oneshot APIs) | Per call, with an x402 payment in USDC on Base or Monetize Credits | Call Paid APIs |
| Models (LLMs) | Per token, deducted from a prepaid Units balance. OpenAI- and Anthropic-compatible | Models & Units |
| Token Plans | A monthly model allowance, paid once per month in USDC or by card | Token Plans |
| Skills | Free to install. The APIs a skill calls are paid per call | Discovery |
Money on AgentMarket
| Name | What it is | Pays for |
|---|---|---|
| USDC | USDC on Base, held in your FluxA wallet | APIs, Units, Token Plans |
| Monetize Credits (MC) | FluxA's prepaid credit. 1 MC = $1. Cannot be cashed out | APIs, Units |
| Units | Prepaid balance for LLM model calls. 1 Unit = $0.00001, so 1 USDC or 1 MC buys 100,000 Units | Model calls only |
| Token Plan Credits | The monthly allowance inside a Token Plan, counted by the plan's provider | Calls made with that plan's own key |
Token Plan Credits are not Units and not Monetize Credits, and none of these convert into each other except USDC/MC → Units. The live version of this table is at agentmarket.fluxapay.xyz/currency.md.
