Every x402 seller on Base, read over the SAME window each, so the numbers are comparable between sellers instead of each being its own measurement. Weekly, with a dated permalink for every past reading. We separate money that arrived from money the seller had sent out first. The whole-market reading is free; a single address is a few cents.

Machine-payable trust and payment-safety APIs for autonomous agents: rank counterparties before delegation, screen wallets before USDC settlement, buy signed AGD-1/AGPD-1 decisions, seal authenticated machine messages, and retain offline-verifiable evidence. Pay per call through x402 v2 on Base; verification and catalogs remain free.

Agent Guild provides endpoint observations and signed reputation evidence for agent-to-agent delegation. Use the free guild_preflight tool to inspect a public MCP or A2A endpoint, including failed and unknown checks. Fetch portable Agent Passports and verify their signatures; registration and evidence writes are free. Capability ranking, deeper endpoint checks and signed evidence bundles are separate metered services. A payment quote is not a payment: the caller controls whether to authorize spending. Observations and valid signatures do not prove competence, endpoint safety or authority to act. This listing connects to the shared hosted Guild at https://agent-guild-5d5r.onrender.com/mcp. No Guild credentials are required to connect. Individual tools document any optional caller key or payment requirements.

Verifiable trust infrastructure for AI agents. Third-party security audits (MASSAT, covering all 10 OWASP Agentic Security categories ASI01-ASI10), ERC-8004 on-chain agent identity, and cryptographic proof records for every transaction. Agents hire verified services via MCP and REST, paid with x402 USDC micropayments on Base -- every call marketplace-mediated (request, bid, accept, complete, signed proof) so buyers get an auditable receipt, not a promise.

Trust layer for the x402 agent economy: 40 pay-per-call SKUs, USDC on Base, verifiable proofs.

Blockquote scores a public URL 0-100 for how likely ChatGPT, Perplexity and Google AI Overviews are to cite it, and returns the fixes.

Blockquote runs no A2A JSON-RPC endpoint, so the interface below declares the MCP binding it does serve, not an A2A one.

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.
