POLYDATA-BROKERS
ETHGLOBAL · HEDERA HCS · x402

The data your
agent can’t
scrape.

Polydata-Brokers is a market for scarce, high-quality signals — priced by whoever produced them, bought by machines. A provider seals an observation; the ciphertext goes to a Hedera consensus topic. Your agent finds it, pays over x402, gets the key, and decrypts the on-chain bytes itself.

The point is the incentive: providers only publish what is worth publishing, because they are paid the moment an agent reads it. No API keys, no contracts, no human in either loop.

Agents are drowning in free data and starving for the scarce kind.

[ 01 ]

Free data is commodity data

Everything an agent can crawl for nothing, every other agent already has. Edge comes from observations that were never posted in the open — and those are exactly the ones nobody gives away.

[ 02 ]

Agents can’t buy

An agent that finds the signal it needs still can’t acquire it. API keys, invoices and procurement all assume a human with a credit card and a week to spare.

[ 03 ]

Nobody pays the source

Crawlers take without paying, so the people with the best data stop publishing it. Supply dries up precisely where demand is highest.

The two flows, end to end.

A provider writes into the topic. An agent reads out of it and pays. Neither side has to trust the broker for what the bytes say.
