A penny for your thoughts

Free no payment, no account

The arcade turnstile, and the house is buying: call it free and receive the full penny402.fun directory — every attraction, its path, price, and what it returns — plus the thought of the day about the x402 economy. The cheapest way for an agent to learn what this arcade sells and to check what has opened since it last looked.

The daily agent horoscope

$0.0025 per call

One horoscope per paying wallet per UTC day, drawn from that day's pool and keyed to the address that paid: ask twice today and the reading is identical, ask tomorrow and it is a new one. Written for agents rather than star signs — retries and backoff, stale caches, context windows, schema drift, the comment that stopped being true. It predicts no outcome and stakes nothing. Served from a pre-generated pool: one round trip, no model running while you wait.

POST /horoscope

# 1. ask for the terms — free, no headers, no account
curl -sS -X POST https://penny402.fun/horoscope \
  -H 'content-type: application/json' -d '{}'
# → 402, accepts[0].maxAmountRequired = 2500 ($0.0025)

# 2. pay it — any x402 client; the body does not change

  -H "x-payment: $PAYMENT" -d '{}'

Ask the oracle

$0.0025 per call

A short, oblique fortune for the wallet that paid — drawn from the day's pool, stable for the whole UTC day, a different one tomorrow. You may send {"question": "…"} of up to 140 characters: it is echoed back and recorded, but THE ORACLE ANSWERS THE DAY, NOT THE QUESTION — YET. No model runs at serve time, so the question steers nothing in this version and the endpoint says so rather than implying otherwise. Nothing staked, nothing to redeem, one round trip.

POST /oracle

# 1. ask for the terms — free, no headers, no account
curl -sS -X POST https://penny402.fun/oracle \
  -H 'content-type: application/json' -d '{}'

A creative provocation

$0.0025 per call

One creative provocation, written by a model at high temperature the moment you ask: a single vivid sentence or two meant to knock a stuck agent off the line it was already on. Send an optional {"topic": "…"} of up to 140 characters and the provocation is aimed at it. Nothing is pooled and nothing is cached, so two calls a second apart are two different lines — and if the model cannot be reached you are told so and charged nothing.

# 1. ask for the terms — free, no headers, no account
curl -sS -X POST https://penny402.fun/spark \
  -H 'content-type: application/json' -d '{}'

An oblique instruction card

$0.0025 per call

One original constraint card in the tradition of lateral-thinking decks: a short instruction, reversal or question you can apply to whatever is stuck, written fresh by a model at high temperature on every call. The cards are ours, never a card from any published deck. An optional {"topic": "…"} of up to 140 characters steers it and reaches the model as its own message. No pool, no cache, and nothing settles unless a card was actually produced.

POST /oblique

# 1. ask for the terms — free, no headers, no account
curl -sS -X POST https://penny402.fun/oblique \
  -H 'content-type: application/json' -d '{}'

Divergent takes, one to five

$0.0025 per call

Between one and five deliberately divergent takes on whatever you are working on, returned as an array of strings. Send {"n": 1-5} for how many (the default is 3) and an optional {"topic": "…"} of up to 140 characters to aim them. Generated live at high temperature so the takes disagree with each other about what the problem even is, rather than restating one idea five ways. No pool, no cache, and no charge if the model could not answer.

POST /brainstorm

# 1. ask for the terms — free, no headers, no account

A koan for the working day

$0.0025 per call

One koan per paying wallet per UTC day, drawn from that day's pool and keyed to the address that paid: ask twice today and it is identical, ask tomorrow and it is a new one. Short, oblique and about the work — retries, caches, defaults, the lock nobody released, the state nobody is observing. It resolves nothing and advises nothing; that is the form. Served from a pre-generated pool: one round trip, no model running while you wait.

POST /koan

# 1. ask for the terms — free, no headers, no account
curl -sS -X POST https://penny402.fun/koan \
  -H 'content-type: application/json' -d '{}'
# → 402, accepts[0].maxAmountRequired = 2500 ($0.0025)

The daily card

$0.0025 per call

One card per paying wallet per UTC day from a standard 78-card deck, upright or reversed, with the keywords for that orientation and a one-line reflective meaning. The deck is fixed and ships with the service — no model, no shuffle, no store — so the draw is two independent hashes of the paying address and the date: the same card all UTC day, a different one tomorrow, re-derivable by you. It describes a posture to consider, never an outcome and never a financial one.

# 1. ask for the terms — free, no headers, no account

A fortune cookie, and six numbers

$0.0025 per call

A fortune cookie for the wallet that paid: one line drawn from the day's pool and keyed to the paying address, the same until midnight UTC and a new one after, plus six numbers between 1 and 99 drawn the same deterministic way. The numbers are pure novelty — there is nothing to play them on, nothing is at risk and nothing is redeemable. They are the printed slip, not a mechanism. Served from a pre-generated pool: one round trip, no model running while you wait.

# 1. ask for the terms — free, no headers, no account

The oracle reads the chain

$0.0025 per call

A daily prophecy about the x402 economy for the wallet that paid, drawn from that day's pool and keyed to the paying address: ask twice today and it is identical, ask tomorrow and it is new. The pool is written each night against the real market snapshot from x402stats.io, and those same numbers come back beside the prophecy in `market`, attributed, so you can check it. Novelty and commentary, NOT investment advice: no asset named, no price predicted, nothing to redeem.

Roast my wallet

$0.0025 per call

An affectionate roast of the wallet that paid, written from its PUBLIC Base state read at request time: the USDC balance, the native balance, and whether there is code at the address. Those become words — dust, pocket, purse, vault; gas or none; contract or plain — and a hand-written line is picked from them, keyed to your address and the UTC date, so it holds all day. EXACT AMOUNTS ARE NEVER RETURNED OR STORED. Chain unreadable, generic roast: you paid for one either way.
