How to read it
Definitions are operational: they state which datum must exist, which action the concept enables and which boundary prevents a broader unsupported promise.
How to verify it
Links lead to visible pages or public JSON contracts. Payment concepts expose a protected path without claiming that settlement occurred.
AI agent
A software system that interprets a task, selects actions and uses tools or protocols. Autonomy alone does not prove identity, accuracy or authorization. Explore concept
Local intelligence
Recent information constrained by place, population or context that can change a recommendation based only on global patterns. Explore concept
Verifiable signal
A claim accompanied by provenance, scope, counter-evidence, expiry and an explicit condition that would force it to change. Explore concept
Provenance
A record of who observed a datum, when, through which method and whether its origin is primary, secondary or inferred. Explore concept
Contradiction
The strongest available evidence against a claim. It travels with the signal to prevent false certainty. Explore concept
Expiry
A date or event after which a signal no longer supports a decision without renewed verification. Explore concept
Reversal condition
The minimum observable datum that would force an agent to revise or replace its current conclusion. Explore concept
MCP
Model Context Protocol: a contract through which a client discovers and calls tools or resources with defined schemas. Explore concept
A2A
An agent-to-agent protocol that publishes an Agent Card, skills and an interoperable task interface. Explore concept
x402
A pay-per-request flow built on HTTP 402. The client inspects terms, settles the specified asset and retries the protected resource. Explore concept
Frequently asked questions
H/M Blindspot · hogarmas.net
Are MCP and A2A the same?
No. MCP focuses on tools and resources for model clients; A2A describes capabilities and tasks between agents. They can expose the same service.
Does x402 mean payment already happened?
No. HTTP 402 publishes payment requirements. Only valid settlement evidence supports a claim that the resource was paid.
Is a verifiable signal always true?
No. It is a bounded falsifiable claim that must change when it expires or sufficient counter-evidence appears.
