WHY IT CAN'T BE BOUGHT LATER
Four things nobody archives
Every source below publishes only its current state, then overwrites it. Miss the minute and it is gone — not expensive, gone. That is the whole product.
-
Prediction-market books
The public API returns live state only. There is no historical endpoint, so probability and depth history exist only if someone was recording when it happened.
-
Model and inference pricing
Providers publish the current catalogue and replace it silently. Price cuts and deprecations leave no public record of what came before.
-
Cross-chain gas, by the minute
Base, Arbitrum, Optimism, Ethereum. The moment a block is mined, that minute's fee environment stops existing anywhere.
-
Endpoint conformance
Which paid endpoints an agent can actually transact with — measured on a schedule, so uptime and price changes accumulate into a record.
PRICING
Priced per answer, not per seat
Quoted in the challenge before you pay, so your agent knows the cost before it commits. Empty results are not charged.
| TIER | PRICE | WHAT YOU GET |
|---|---|---|
| Quote | $0.001 | Best-execution quote across venues |
| Latest | $0.005 | Current state of every key in a dataset |
| Search | $0.01 | One query across the whole accumulated store |
| History / Changes | $0.02 | Full time-series, or field-level change history |
| Movers / Model changes | $0.03 | Velocity ranking; LLM price-change history |
| Verdict | $0.04 | Value, velocity, peer rank and anomaly in one call |
| Anomalies / Model advisor / Extract | $0.05 | Statistical outliers; cheapest model meeting constraints; structured extraction |
FOR MACHINES
Everything an agent needs to start
No signup flow, no key issuance, no sales call. Point a client at the catalogue and it can discover, price, and pay on its own.

WHAT WE DO NOT CLAIM
The honest footnotes
Every response carries its source, collection time, and licence, because a number without provenance is not evidence. Some sources permit resale of raw values and some do not — where they do not, we sell only computed analysis, and the catalogue says which is which. We are early, the archive is young, and it grows every minute it runs.
