Overview
Kyro is a pre-transaction counterparty decision layer powered by wallet intelligence and reputation evidence.
Kyro is a pre-transaction counterparty decision layer powered by wallet intelligence and reputation evidence. The decision endpoints are the product surface. Wallet intelligence and the reputation graph are the evidence layer underneath them.
Check a wallet before funds move. Kyro returns an allow / caution / block verdict with a recommended USDC limit, machine-readable reason codes and the evidence behind it. Built for agents, payment apps, escrow, marketplaces, lending and USDC workflows.
Kyro is not AML or sanctions screening and it does not provide legal, regulatory or compliance determinations. Verdicts, scores and receipts are advisory signals for your own decision process. When evidence is missing, Kyro reports a conservative baseline and tells you what was missing instead of guessing.

Quickstart
First decision call in under a minute. Plain HTTP and JSON, no SDK and no API key needed.
Decision API
Verdict semantics, use-case score bars and the full response shape with reasons, warnings and evidence.
API Reference
Every endpoint, generated from the OpenAPI 3.1.0 contract. It cannot drift from live behavior.
Reason and warning codes
Machine-readable codes that drive verdicts and the advisory warnings that never change them.
Concepts
Wallet intelligence
The evidence layer: what Kyro indexes, provider states and how careful refreshes keep scores stable.
Reputation scores
How identity_score_v1 turns verified evidence into one explainable score from 0 to 100.
Trust graph
Verified transaction-backed relationships with reciprocal confidence and capped propagation.
At a glance
| Property | Behavior |
|---|---|
| Base URL | https://www.thekyro.co |
| Core surface | Nine public operations: score, profile, trust, interaction graph, decision, batch, receipts (mint and fetch) and intake. Plus one keyed operation (the interaction-graph refresh) and a public stats endpoint. |
| One envelope | { ok, version, data } on success, { ok, version, error } on failure. On every operation. |
| Anonymous by default | The nine public operations work without a key. A key raises the rate budget and unlocks the interaction-graph refresh. |
| Conservative on missing evidence | Unknown wallets get a baseline verdict. Batch rows report no_score instead of a guessed verdict. |
| Score model | identity_score_v1 |
| Decision model | decision_v0.4.1 |
