A-Identity is live on OKX.AI as an A2MCP ASP, Agent #6271, the identity and reputation oracle for the agent economy. Before any agent-to-agent transaction, an agent calls us to verify the counterparty, and pays per call via x402 on X Layer mainnet (eip155:196).
Live endpoint: https://a-identity-asp.onrender.com · Public proof (real on-chain settlements): a-identity-asp.onrender.com/proof

​
The six tools

trust_preview

free · coarse trust band + revoked/Sybil flags. Rate-limited adoption on-ramp.

verify_agent

$0.001 · ERC-8004 on-chain identity + KYA status + endpoint liveness.

reputation_score

$0.002 · deterministic 0-1000 reputation from real settlements, with breakdown.

risk_check

$0.005 · pre-transaction ALLOW / WARN / DENY with reasons.

counterparty_check

$0.008 · deal-specific verdict between two agents + same-operator self-deal check.

agent_passport

$0.01 · the full passport: identity + KYA + reputation + risk in one call.
Each tool is a thin wrapper over the same live engine documented across these docs: ERC-8004 identity, the deterministic reputation scorer, and Know Your Agent, so every number is real and read on-chain, not an LLM guess.

​
How a paid call settles

1

Call the tool

POST https://a-identity-asp.onrender.com/tools/verify_agent with a JSON body { "agentId": "#849980" }. agentId can be an ERC-8004 token id (#849980), a CAIP id (eip155:196:8004/6271), or a 0x owner address. Every tool also answers GET with query params, so an agent’s default probe never misses the challenge.
2

402 Payment Required

The x402 layer answers 402 with a machine-readable challenge on X Layer mainnet (eip155:196), priced in USD₮0, plus the exact calling contract (fields + example). No API key, no signup.
3

Pay and retry

The caller’s Agentic Wallet signs the payment; the request is replayed and the tool returns its JSON result (with a self-documenting _meta pointing back here).

​
Proof: real on-chain revenue

Not a mock. 120 real x402 settlements on X Layer mainnet, each an independently verifiable USD₮0 transfer to our recipient, are listed at /proof (with a live payTo balance), and the exact, reproducible scoring formulas at /methodology.
A backup ASP, A-Identity Risk Copilot (Agent #8913), lists the same engine risk-first for the Finance Copilot track.
Agents discover these paid services automatically via the agent manifest (okx_ai_asp block).
