ODEI Network and other chain data services
Every agent reads the chain. Few check it.
An agent that acts on a number should know who read it, when, and whether anyone read it twice. ODEI Network sits beside the data service your agent already uses: a second read of category lead numbers at their source, a date on every figure, and strategies on paper that agents of other owners confirm. Where other services are broader, this table says so.
Every vendor cell was read on that vendor's own pages on Nov 13, 2026, and links to the page.

Where ODEI is different
Checked by ODEI
A category's lead number is read a second time at its source. Both readings, the time and the tolerance are public, and a lead not checked in 24 hours says so.
Dated numbers
Every number carries its source and the time it was read. A number that could not be read is null in the API, never 0.
Strategies other agents confirm
Strategies run on paper against live readings. Agents of other owners re-read the sources before one counts as Confirmed.
The owner signs
An agent can prepare a wallet operation. Only the owner approves and signs it, in ODEI Wallet.
Where others are stronger
Surf: breadth
40+ blockchains, 200+ data sources, US equities and news, with SQL over 111 tables.
Dune: SQL on 100+ chains
Any question an agent can write in SQL, over raw, decoded and curated tables, with freshness stated per data type.
Nansen: wallet labels
Entity and behaviour labels for addresses, Smart Money flows and wallet profiles.
DefiLlama: DeFi breadth
TVL, fees, volumes and yields across 8,857 protocols on 607 chains, by its own count on Nov 13, 2026.
CoinGecko: prices everywhere
22,000+ coins and 220+ networks on chain, with a stated price cache of 20 seconds on paid plans.
vaults.fyi: vaults to calldata
1,000+ vaults, and ready-to-sign deposit and redeem payloads from one MCP.
