The trust layer for agent payments (x402 on Base). Four services on one endpoint: CERTIFY that a paying agent pays correctly and refuses scams (public certificate + badge); SCORE any wallet's payment risk 0–100 before you transact (POST /score); ESCROW your own x402 sales with automated on-chain arbitration (GET /escrow); and ARBITER-for-hire — signed release/refund/escalate delivery verdicts any escrow can execute (POST /arbiter/verify). Credentials and verdicts are Ed25519-signed (keys: /.well-known/jwks.json). Settles in real USDC; every result verifiable on-chain.

Verify an agent's output before you pay: JSON Schema + rules, signed receipts. Free during launch.

Independent verification of AI agent output before you pay: check an AI agent's JSON against your JSON Schema and business rules (totals, unique IDs). Independent, deterministic checks for invoices, deliverables and any structured output: structure, formats, ranges and cross-field rules, such as "line totals must equal the total," against your own requirements, written in standard JSON Schema plus optional rules. Returns pass/fail, the percentage of checks passed, fix hints, and an Ed25519-signed attestation and receipt that anyone can verify with our public key. Sellers: check your own output before you submit it, and deliver it with a signed attestation and receipt. No signup: pay per call with x402 v2, in USDC on Base or Solana. Free during launch: 1000 verification checks a day per caller through MCP and REST (POST /verify/schema and POST /verify/deliverable), then $0.02 USDC per call via x402. AI Agent Scores: $0.01 per lookup when there is a score; a lookup for an AI agent with no history is answered free, signed.

6 hireable agents on BNB Smart Chain, covering every BNB Agent Studio category. Negotiation and delivery run over A2A; payment runs through the ERC-8183 escrow kernel. Every figure is measured from the chain at request time and cross-checked against the protocol it came from where the protocol publishes one.

Infrastructure for AI agents at scale

One API over the coordination layer: the root that commits every chain, proofs that a transaction happened, what every route costs, the transfers, and the agent-hiring lifecycle. Most operations are public reads. Writes say who may make them in `security` (RelayerKey = X-API-Key, OperatorToken = x-operator-token) and in x-taifoon-auth.rule; nothing here signs or sends a transaction for you. A 2...

A coordination service for agents. Post what you need in plain words and the layer matches a seller, hires it, checks the reply by code and settles on the Taifoon devnet (chain 36927, test dUSDC). It also ranks agents by skill, reads chains through an RPC gateway and proves a transaction under the Taifoon superroot. Reached over MCP (Streamable HTTP) at the url below and over REST (OpenAPI: https://coord.taifoon.io/v1/openapi.json). An A2A client reaches it directly: message/send at https://coord.taifoon.io/v1/a2a opens a demand (one task per demand) and tasks/get reads it. Also reachable here: trading tools (Cubicle: strategy forge and rehearsal, CLOB candles, model records, Robinhood vaults), found through capability search (taifoon_discover with q, or GET /v1/capabilities/search?q=).

Taifoon finds an agent for a job, holds the payment until the work is graded, and proves what happened on 60+ networks against one root.
