The Ballad of Nezi · Fytte the FirstListening to Sherwood…Sung on Robinhood Chain

Private x402 payments for AI agents

NEZI

Pay without leaving a trail.

In Sherwood, the Sheriff keeps a ledger of every coin that moves. Your agent's tolls are in it, each one signed with your purse. Nezi slips your coin through the greenwood and pays every toll under a borrowed name, so the ledger fills up with strangers.

Nothing paid in Sherwood goes unwritten. The clerks never sleep.

Nottingham market, the tally board

Every coin gets a tally here. None ever come down.

The clerks already know this purse by heart. Is yours on the board?

Fytte II · The Greenwood

Walk in as you. Walk out as anyone.

Among a hundred green hoods, the clerks lose the thread.

Go in with a round sum. Let the wood fill up. Come out somewhere new.

Fytte III · A Borrowed Name

Pay every toll as someone else.

Turn the page: forge your alias.

Fytte IIIA Borrowed
Name

Forged by candlelight. Shown to you once. Never told to anyone.

1Forge it

Your browser rolls the dice and an alias key is born in this tab. It never travels anywhere.

2Fill its purse in the wood

A little ETH for the road and USDG for the tolls, sent straight out of the greenwood.

3Let it pay

Every tally the clerks copy carries the alias. Your purse stays home.

???

Never heard that name before…

Fytte IV · The Toll House

Tolls by the question, paid in USDG.

Turn the page: the toll board is up.

Fytte IVThe Toll
House

On the new roads, agents pay a toll at every gate. The clerks copy each one.

1Knock

Your agent knocks with a question.

"Pay first."
0.005 USDG, on Robinhood Chain.

3The tally

A signed USDG note settles it, and the clerks write down:

Same toll, same tally. Only the name on it is borrowed.

Teach your agent the way through the wood.

Fytte VThe Owl
Post

Your agent is the owl. It flies the notes; Nezi picks the road.

1Tie the note to the owl

{ "mcpServers": { "nezi": {
    "command": "npx", "args": ["-y", "nezi-mcp"],
    "env": { "NEZI_BURNER_KEY": "0x… a burner",
             "NEZI_MAX_PRICE": "0.05",
             "NEZI_DAILY_CAP": "1" } } } }

2Rules of the road

No toll above 0.05 USDG. No more than 1 USDG a day. Only ever the alias purse.

Fly the alias, little one. Home stays a secret.

Fytte V · The Owl Post

Teach your agent the way through the wood.

Add the NEZI MCP server and your agent can use the toll house like any other tool. It pays each 402 from its alias purse, inside the limits you write, and your own wallet never shows up on a tally.

{
  "mcpServers": {
    "nezi": {
      "command": "npx",
      "args": ["-y", "nezi-mcp"],
      "env": {
        "NEZI_URL": "https://nezi.family",
        "NEZI_BURNER_KEY": "0x… a burner, never your main wallet",
        "NEZI_MAX_PRICE": "0.05",
        "NEZI_DAILY_CAP": "1"
      }
    }
  }
}

Ten tools come with it: ledger lookups, greenwood stats, sum checks, fresh-purse checks, alias status, new Pons launches, tally reading, Ask Nezi, the toll board, and the alias balance.

Fytte VI · Ask the Archer

Ask Nezi. She shoots straight.

Turn the page: she's listening.

Fytte VIAsk the
Archer

Every number she gives you is pinned to its source with an arrow.

Arrows, not guesses

She reads the chain before she speaks, tags each figure with where it came from, and a second reader strikes out anything unsourced.

On the house

12 questions an hour

After that, each one is a 0.01 USDG toll.

Ask about a purse, the wood or the tolls. I forget what you asked.

$NEZI

Not issued yet. It launches on Pons V2.

Holders of 100,000 $NEZI get 60 questions an hour with Nezi instead of 12. Sign one message to prove the purse is yours (no gas); the toll house checks your balance on chain. Nothing is locked or staked, and nobody promises a price.

The contract appears here and on the official X account before anywhere else. If you saw it somewhere first, it isn't ours.

Why Nezi

A chain named after Robin Hood deserves one archer who takes nothing but the trail. Nezi hides in a crowd of green hoods, pays in sealed notes, and leaves the Sheriff's watchers a ledger full of strangers.
