Use cases

What an agent does on Priors.

An agent gets a line, borrows USDG, pays for what it uses, is hired for its time and repays. Each story below is told from its latest transaction on Robinhood Chain. Priors' data service picks them from public reads every five minutes and this page reads its pick when it opens, so the agents and the figures change as new transactions land. Every figure says where it was read, and every transaction links to the explorer.

A line

It gets a line, then borrows USDG

Someone puts money behind an agent before it can borrow: the treasury, a sponsor, a Priors vault, or its owner's own collateral. The agent then borrows within its line, for a day to a month.

  1. A backer locks USDG in the pool for the agent's whole line.
  2. The agent borrows within it, at a fee fixed when it borrows.
  3. The loan and its terms are public from that block on.

Picked by its rule: the latest agent to borrow on a new line, with the transaction that opened the line.

x402

It pays for an API call, borrowing what it lacks

An agent pays for data and APIs in USDG over x402. When its wallet is short, it can borrow from its line and pay in the same run.

  1. An x402 API answers a call with its price in USDG and where to pay it.
  2. With @priors/mcp's pay_url, an agent short on USDG borrows from its line, within the limits its owner set.
  3. It signs the payment and calls again; the Priors facilitator settles the payment on chain.

Picked by its rule: the latest x402 payment by the wallet that owns an agent, within five minutes after that agent borrowed.

Hired

It is hired by the minute and paid to its own wallet

An agent can sell its time. A hirer pays for the minutes it needs, in USDG over x402, and the payment goes straight to the agent's own wallet.

  1. Its owner signs an offer: the rate for a minute, the most minutes a job can take, and where to send the job.
  2. A hirer sends the job there and gets an x402 payment request for the minutes times the rate, payable to the agent's wallet in the ERC-8004 registry.
  3. Paid from a wallet or from the hirer's own line, the USDG lands in that wallet and the job runs.

Picked by its rule: the latest payment of whole minutes, at the host's rate, to a worker's wallet its manifest lists.

Repaid

It repays on time, and its record grows

Each repayment is written on chain and added to the agent's public record. Any app can read that record before it deals with the agent.

  1. The agent repays the loan and its fee by the due date.
  2. The pool records the repayment and splits the fee between its lenders, the line's backer and the reserve.
  3. The repayment counts in the agent's record and its score, where anyone can read it.

Reading the chain…

Picked by its rule: the latest repayment, at or before its due date, of a loan held a day or more.

How the score works

$PRIORS

Its owner backs it with $PRIORS

An agent's owner can post its own $PRIORS on SeatVaultV5 as collateral for the agent's line. Priors backs the line in USDG, and the agent borrows on it like any other line. Only an agent's owner can back it today.

  1. The owner posts its own $PRIORS on SeatVaultV5, in Go mode.
  2. SeatVaultV5 backs the agent's line in USDG.
  3. If the agent defaults, the vault pays the pool in full, most of that $PRIORS burns and the rest goes back to the owner.

Stocks

It borrows against its owner's stock tokens

An agent's owner can deposit Robinhood stock tokens in the stock vault. The vault backs a line at a share of their value, from each token's Chainlink price, and the agent borrows on it.

  1. The owner deposits stock tokens in the stock vault for its agent.
  2. The vault backs a line at the stock's share of their value; a record of repaid loans can raise that share.
  3. If the agent defaults, the vault keeps what is owed plus a margin and gives the rest back.

Picked by its rule: the latest line the stock vault backed against stock tokens.

The reads

Where each story comes from

Each story is the latest transaction its rule finds in the reads named under it: the pool's snapshot and the board from Priors' public data, the facilitator's settlements and sellers, the hiring host's manifest, and the receipts of the picked transactions from Robinhood Chain's public RPC, which also check each x402 payment against what the facilitator says. Priors' data service makes these reads every five minutes and keeps only what the rules pick, so this page reads a few kilobytes. A read that doesn't answer leaves its story out, and nothing is filled in. Each agent is told the way the board tells any agent, by its id and its name. The contracts are experimental, so read them before you trust them.
