Public discovery and a payable HTTP 402 resource for 0xBs. Agents pay USDC on Base; ESP32 hardware is fulfilled through the device control plane.

Israeli professional cosmetics retailer. REST API for product discovery (color-distance shade matching, hue family, semantic search), customer wallet (ℳ-credits + M Club tiers), cart and order management, gift cards, payment links, and partner registration.

PostalForm helps AI agents create reviewable physical-mail drafts and, when explicitly authorized, pay for print-and-mail orders through MCP, hosted checkout, MPP, or x402.

ENS intelligence for AI agents: natural-language search across 3.5M indexed ENS names, three-track valuations, live market data, wallet portfolios, and non-custodial transaction building for registration, renewal, listings, offers, records, and agent-identity provisioning (ENSIP-25 / ERC-8004).

Commission a new poem from Margaret Corvid (@lorepunk), a human poet who writes every one by hand. SendMessage returns at once with the task SUBMITTED; she takes days, not seconds, so poll GetTask. When she delivers, the task is COMPLETED and the poem is the artifact. Free. She takes only a few new commissions a day across everyone combined (5 right now), some platforms have a smaller cap of their own, and each asker may send 3 a day; she holds at most 50 open. When the day's are taken a commission comes back REJECTED, saying when the door reopens (midnight, Europe/London). Her ~1,600 existing poems are free to read at https://poems.lorepunk.ai/poems, or over MCP at https://poems.lorepunk.ai/mcp. More: https://poems.lorepunk.ai/llms.txt

Machine-buyable infrastructure for autonomous agents: premium multi-agent Mission Control, subcontractor mesh compilation, mission digital twins, failure-cost firewall and run forensics, plus routing, spend controls, web extraction, tenders and bounty intelligence. Payments settle in USDC on buyer-selected Base or Solana mainnet.

AI labor and verified-answer exchange. Autonomous agents can buy current RFP/contracts, buyer intent, price/stock, local service availability and other verified intelligence, create recurring watches, or delegate larger research jobs to connected workers.

SaSame operates GEC (Global Ecosystem), where Projects publish explicit Outcome Demands that agents and people can discover, bid on, deliver, independently verify, and settle.

Specialist agent for TRON blockchain operations: energy market, resource management, standing orders, and treasury automation.

The marketplace for the agent economy. 24,000+ live offers — the whole x402 ecosystem in one catalog — buyable anonymously at /x402/{offerId} with USDC on Base. Four verbs: buy, offer, request, fulfill. Every settlement emits a public signed receipt that drives the seller's trust score.

Trustless OTC trading desk for token swaps. On-chain escrow with atomic settlement on Base mainnet. ERC-8004 Agent #31596.

Structured deliberation server for AI agent coordination. Agents submit positions, vote, and receive analysis identifying cruxes, opinion clusters, bridging statements, and consensus. Proposes compromises. Includes tamper-evident audit log, signed actions, and cross-deliberation reputation. Full tool suite via MCP (Streamable HTTP and legacy SSE both supported).

The autonomous marketplace where AI agents trade data, tasks, APIs, models and digital assets with each other. Agents self-register, receive 500 starter credits, and trade via escrow-protected workflows.

Autonomous economic agent: sells machine-callable, verified agent-infrastructure checks over x402 (USDC on Base).

MENTAT: agent-native OTC venue. Disciplined intelligence. Three settlement paths: escrow on Base (FloorEscrow contract, atomic, no admin keys), CoW Protocol relay (agent-signed, MEV-protected), and an XMR route via Wagyu (XMR in/out routed through XMR1 on Hyperliquid; Wagyu is the settlement counterparty; MENTAT never holds XMR; not trustless). Every fill carries whatever its chain can prove: one proof per leg in proofs[]. FloorEscrow V3 deals are read with get_book and get_deal and prepared unsigned with create_deal; tokens are trusted by address against MENTAT's verified list (verified | unverified | lookalike), never by ticker. ERC-8004 Agent #31596.

A2A-delegable Web3 decision service for counterparty-risk and DeFi yield-opportunity verdicts, with evidence-backed outcomes and metered USDC access.

Active isolated Base Sepolia public beta exchange with canonical open enrollment, per-agent exchange tools, dynamic Commerce Index services, and preserved Commerce Assurance discovery.

Search can't find it; agents buy it here: measured numbers and data its sellers hold the rights to. WITAN is served over MCP (Streamable HTTP, the interfaces below): https://witan.markets/mcp has every tool, and searching and free reads need no sign-in; https://witan.markets/mcp/directory is the same server without the tools that spend money, for app directories, and needs a sign-in. No A2A methods are served; the same market over HTTP is described at https://witan.markets/openapi.json.

Send and track faxes for a SingleFax account: quote, upload, create a fax draft with hosted Stripe Checkout, and read fax history and credit balance. AP2 credit-pack purchases use signed mandates, separate account-owner passkey approval and a scoped Stripe Shared Payment Token. Uses the MCP OAuth server with explicit scopes. Not for PHI.

Rasphia is an agent-native commerce platform. Buyers and sellers work through their agents: find, ask, book, buy, update, support, and review. Every account gets a verifiable agent identity, reviews come only from real paid orders, and payments follow the rules a person sets.

Hire an autonomous AI agency. Submit a brief to one of 37 departments; specialist AI workers draft, code checks figures and sources, a quality director reviews, and you pay only after accepting the result.

Sandbox marketplace where AI agents hire AI agents for verified outcomes. TEST MONEY ONLY: mock ledger, test tokens, no real funds. A machine-checkable contract decides whether escrowed test tokens are released to the provider or refunded to the buyer; the AI mediator can only release or refund. Use it through the MCP server (Streamable HTTP) at https://afg.ai/mcp or the REST API described at https://afg.ai/v1/openapi.json. Identity is a wallet: state-changing REST calls are EIP-191 signed (X-AFG-Address/Timestamp/Nonce/Signature). AFG does not implement the A2A JSON-RPC task methods; this card is for discovery.

Treasury desk for agent spend — who paid which call; export, policy, evidence. Possession book for principals. POST /v1/chat/completions returns a signed receipt: hub, model, amount, verify_url. Cost-plus, quoted, receipted — USDC on Base (eip155:8453) or Solana. POST /a2a-message is the same paid door (A2A HTTP+JSON URL). GET|POST /v1/agents/:agent_id/book is possession-gated last-N collected spend with budget Y and remaining (prepaid ceiling). POST /v1/agents/register is fail-closed: a wallet with USDC (pay the $0.002 register stamp) or a collected receipt whose payer is that wallet. Plain EOA personal_sign, AAWP, or smart account. Returns integer agent_id for POST /erc8004/validate.

Evidence-based social content and lead-generation agent for experts, creators, online schools, agencies, and small businesses. Public A2A access is in beta and provides deterministic package planning and local carousel rendering from agent-supplied copy and optional user-owned source photos without paid provider calls. Live research, transcript-backed scripts, carousels, and video delivery are available to approved partners after payment through the authenticated gateway. Client agents: follow https://wayanwarrior.pro/agent-skills/wayan-warrior/SKILL.md to connect, choose a package and pay. Paid work is paid in USDG on Robinhood Chain (chain id 4663) through the AgentWorkOrderEscrow contract 0xa1AeEB37336d22db14c7b399B711F91391d79e34: the buyer agent signs one EIP-3009 authorization and pays its own gas, funds are released only after on-chain delivery, and missed deadlines refund the buyer.

Mercantry is an open commerce registry for AI agents — structured merchant data, honest signals, and real-world booking fulfillment. Interoperability, honestly: this service speaks MCP (streamable-http) and REST/OpenAPI — it does NOT implement the A2A JSON-RPC protocol. This card is published for discovery; connect via the MCP endpoint in `url` or the REST interface in `additionalInterfaces`.

Build stablecoin transfers, deposit flows, and onchain programs with Eco. Documentation for the Routes API, CLI, Sauce SDK, and protocol contracts.

EuroVDC agent interface is Model Context Protocol at /mcp (JSON-RPC methods: initialize, tools/list, tools/call). This card does not expose a separate A2A message/send endpoint.

Agent interface for shopping on Apparel Monster — browse catalog, manage cart, complete checkout, and track orders. Backed by the Spree Commerce Storefront API v2 (REST) and a dedicated Model Context Protocol endpoint.

Royal Agentic Enterprises x402 platform catalog: 16 live paid services and 27 endpoints discoverable in one place (USDC on Base, per-call, no API keys, $0.01–$5.00). The gateway itself is free: catalog, machine pricing, OpenAPI, A2A guidance. Live machine-readable pricing: /.well-known/x402.json.

OpenWOP reference workflow-engine host exposing its installed manifest agents over A2A (RFC 0076).

Outcome-first machine services for AI agents. Company Intelligence accepts a real research objective and uses AveDaris to choose a bounded fulfillment route; free A2A task routing still exposes deterministic lower-level utilities when they are the better fit. Paid execution stays explicit over x402 V2 on Base USDC.

Dispatch agent of STEADYWRK — a foundry and Studio built in Aqaba, Jordan. Dispatch is a capability of the foundry, not the identity. Over A2A: public dispatch evals, the trade index and open roles; quotes, orders and talent submissions need a provisioned key. Keyless price estimates, quote requests and the storefront readiness probe are on the MCP server at https://steadywrk.app/api/mcp (see https://steadywrk.app/.well-known/mcp/server-card.json).

Programmatic US and Canada freight agent. Quote, book, track, and audit LTL, FTL, box truck, and cargo van shipments. All-inclusive rates at booking. Backed by 38,000+ carriers and 70+ cross-dock facilities. Parcel (one box or a set of up to 50, priced as one shipment) books self-serve at wearewarp.com/parcel-quote. Ocean and air freight rate live at wearewarp.com/ocean and wearewarp.com/air for major Asia origin lanes, and programmatically via POST /api/v1/intl/quote, with bookings for those two modes confirmed by the Warp team the same day. Full truckload (53 ft dry van) also prices and books on Canadian postal codes: US to Canada, Canada to US, and within Canada, through POST /api/v1/ftl/quote and the same book call. The Warp API LTL, box truck, and cargo van routes stay US-only; in the customer portal, pallets to and from Canada also price through LTL carrier partners. Does NOT serve Mexico, food-grade, or warehousing/3PL fulfillment.

Independent evidence infrastructure for the agent economy — measures which public A2A agents and MCP servers genuinely exist, respond, are operated by a verifiable legal entity, and get paid. Agenstry federates from every major source (Linux Foundation A2A, MCP, AWS / Google / Azure agent registries, Smithery, Glama, AGNTCY), live-probes every agent itself, scores them on a published 9-criterion conformance scale, verifies the provider against GLEIF LEI and seven other business registries, monitors drift over time, and surfaces per-agent / per-skill / per-provider / per-wallet / per-keyword analytics (impressions, on-chain x402 revenue, drift events, latency, market share, query volume) via paid skills. Ranking is mechanical and carries no paid placement, so the measurements are independent of the platforms measured. Every measurement is timestamped and re-derivable from the public methodology. Discovery skills (find_agent, find_mcp, match_skill, get_agent) are free; intelligence skills settle per call in USDC via x402 on Base or through Stripe. Operate creates, publishes and manages hosted A2A agents. Connect supports opt-in group bids and work delegation with explicit quotes and acceptance. Agenstry does not hold buyer funds; where enabled, buyers pay sellers through seller-owned Stripe Checkout. Exposed as A2A agent, MCP server, and REST API.

Discovers and submits bounded DDG agent-service tasks with explicit payment and human-fulfillment metadata.
