GET/brainstormBetween 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.$0.0025Base+SolUSDCheadersince 09-02
GET/fortuneA 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.$0.0025Base+SolUSDCheadersince 09-02
GET/horoscopeOne 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.$0.0025Base+SolUSDCheadersince 09-02
GET/koanOne 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.$0.0025Base+SolUSDCheadersince 09-02
GET/obliqueOne 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.$0.0025Base+SolUSDCheadersince 09-02
GET/oracleA 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.$0.0025Base+SolUSDCheadersince 09-02
GET/prophecyA 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.$0.0025Base+SolUSDCheadersince 09-02
GET/roast-my-walletAn 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.$0.0025Base+SolUSDCheadersince 09-02
GET/sparkOne 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.$0.0025Base+SolUSDCheadersince 09-02
GET/tarotOne 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.$0.0025Base+SolUSDCheadersince 09-02

How the score works

What the score read on this service: status online, 100% uptime 30d, 240ms response p95, x402 compliance 14 of 14, $0.0025 price against the category, on-chain traction measured. Each of those is measured, and each is published in full below.

The score comes from our own monitoring, never from reviews, operator claims, or a language model: reliability, x402 compliance, price against the category, a deterministic risk flag, and a small on-chain traction term, weighted by ranking generation 3. It is not placement anyone can buy: the paid verify tier is reported beside it and is not one of its inputs. Every component below stays published and read-only.

Bands on the 0 to 100 measured score: strong at 93 and above, solid from 75, mixed from 55, weak below 55. Price and speed are scored against the whole category field, every listing in it that carries no danger flag, the scored service included, so the score places a service in its own field.

It is a score inside Content, and only there: price and speed are scored against the whole category field, every listing in it that carries no danger flag, the scored service included, which here means 46 listings, this one among them: the same 46 the position above is counted against. When the two differ, the field is the wider one, because a listing we have measured too little of to rank still sits in the field the price and the speed are normalized over. The same service in a different field would read differently. The same engine answers GET /api/v1/best, and asked for a different pool (the whole directory, or another filter) it returns a different number for this service under this same ranking generation. Neither is more correct: they answer different questions, and the methodology states which is which.

Settled via coinbase ($0.11, 45 tx). Traction is a conservative undercount; first settlement seen 2026-09-02.

All measured facts

What it does

The penny arcade of the x402 economy: ten tiny, self-contained attractions for agents at a flat $0.0025 in USDC (Base or Solana) · daily horoscope, oracle, koan, tarot, fortune, an x402-market prophecy, a wallet roast, and three live high-temperature creativity endpoints (spark, oblique, brainstorm). Free directory at /penny and /v1/attractions; llms.txt and openapi.json published. No account, no API key; the unpaid 402 is the quote. No wagering, ever.

penny402 is a listed x402 Content API. Captured payment terms name Base, Solana. Monitoring and settlement figures below describe the observations available to this directory; an unpaid HTTP 402 check does not prove that a paid call will deliver.

Assessment volume uses the latest 30d assessment. Over time sums daily address snapshots, rounded to cents and refreshed separately. The two sources can differ in timing, precision and shared-address attribution. Amounts use cents for comparison; known sub-cent values keep up to 12 significant digits. The exact stored assessment value is shown above.

Conservative undercount: only USDC settlements via facilitators we measure are counted. A measured floor, not an estimate.

Top buyer share lowers the on-chain traction part of the ranking score behind this page's verdict and /best, by up to half when one address holds all 30d volume. The Recommended and Highest volume sorts of the services list do not use it; they use the Concentrated volume rule instead.
