Reliable answers from the real world.

Eckari gives software agents deterministic access to authoritative real-world capabilities through one consistent interface.

Company records, legal entities, domains, official rates, weather, location data and more — returned as clean structured answers without provider-specific integration work.

Agents need outcomes, not another integration.

External services expose different credentials, schemas, terminology, limits and errors. Eckari turns them into stable capabilities with predictable inputs and canonical outputs.

Ask for the job

Capabilities are named around what the agent needs to accomplish, not around the provider that happens to answer.

Get a canonical answer

Provider-specific responses become predictable Eckari outputs with stable field names and derived flags.

Know what you received

Freshness, source and stated limitations travel with the result, so an agent can reason about it.

Designed to be easier for machines to trust.

Deterministic

Known inputs, bounded execution, stable output contracts.

Authoritative

Capabilities read defined sources — Companies House, SEC EDGAR, GLEIF, the ECB, the NWS, the Census Bureau, registry RDAP — with explicit provenance.

Canonical

Agents receive Eckari-shaped answers rather than provider-shaped payloads.

Accountless

Machine-native x402 payment per capability call, instead of another account and integration.

Honest failure

If a capability cannot be fulfilled to contract, Eckari fails clearly instead of inventing an answer.

Every answer explains itself.

Source, freshness and request provenance travel with the result, so the consuming agent knows what it received and when it was read.

}

When retrieval isn't the job.

Search and browsing are excellent when an agent needs to investigate the open web. Eckari is for defined real-world facts and outcomes where an authoritative, structured answer is more useful than another page of results.

Retrieval

“Read what this website says about its ownership.”

Eckari

“Who are the registered persons with significant control for this UK company?”

Retrieval

“Find articles discussing this domain.”

Eckari

“When does this domain registration expire?”

The agent integrates with Eckari. Eckari handles the providers.

Capability code shares a common execution, payment, provenance and error model, so adding another real-world capability does not mean adding another integration architecture to your agent.

Pay for the capability you use.

Eckari supports machine-native x402 payments. An agent can discover a capability, accept its published price and pay per call without opening an Eckari account.

Conventional account and API-key access is part of the Eckari architecture and will open separately.

One MCP server. A growing capability set.

Connect Eckari once and expose the whole capability catalogue to an MCP-compatible agent.
