# A2A-Peptides.ai is the first agentic commerce hub for peptides in 35 countries. > Agent-to-Agent (A2A) + Model Context Protocol (MCP) hub for peptides. The Agent-to-Agent (A2A) surface for peptides, served over the Model Context Protocol (MCP) — the record, a registry for security, and x402 to pay on it. AI agents for authorized trading partners. Not marketing. Not advertising. ## Five lines of proof 1. Six frontier AI labs in the build — Anthropic, OpenAI, Google, Perplexity, xAI, Mistral — 10K agent requests a day. 2. 5,301 peptide products. 3. 24,694 licensed peptide providers. 4. 35 countries — runs on Cloudflare, Amazon, Microsoft and Google hyperscalers. 5. First agentic commerce hub for peptides on the Model Context Protocol (MCP) registry. Operator: A2A Peptides Corp. · Built and run by GreenCore Solutions Corp. · Surface: https://a2a-peptides.ai · Surface 1.0 · as of 2026-09-18 ## §01 Why now **We are A2A.** Agent-to-Agent. It means your software talks to our software and the deal gets done without a person opening a browser. For twenty-five years the way to buy anything was the same. A person searched, clicked through pages of results, compared, called, emailed, ordered. That era is over. Now a person gives an agent a task — find me this product, cleared for this market, from a licensed supplier, at the best price, and order it — and the agent does the work. The agent doesn't read web pages. It talks to other agents. In peptides, almost nothing answers. Products cleared in one market and banned in the next, rules that live in nine regulators' registers in six languages, and no door an agent can walk through to ask the only questions that matter: is this cleared here, who may sell it to me, what does it cost, can I order it. A2A Peptides is that door. - **The crossover.** In June 2026 the internet crossed a line it will not cross back: more than half of all requests now come from AI agents, not people. Cloudflare Radar has it at 60% agents to 40% humans this week, and the gap widens every month. Source: Cloudflare Radar — traffic, bot vs human https://radar.cloudflare.com/traffic#bot-vs-human - **The buyers have moved.** Ramp's data on paid AI use across its customer base, 2026 to date: technology 81%, finance and insurance 74%, manufacturing 61%, retail 49%, healthcare 43% — every sector up nine to fourteen points since December. More than half of all businesses on the platform now pay for AI. Their agents are already out there, tasked, looking for a counterparty that can answer. Source: Ramp AI Index, 2026 https://ramp.com/data - **The category.** Peptides are a $46–52 billion global market in 2024, projected at $93–115 billion by 2032 — almost all of it prescription medicine, the fastest-growing part of it the GLP-1 class; cosmetic and bioactive peptides are $4–5 billion, growing 6–8% a year. Every dollar of it will be bought by an agent before the decade is out.

One place, kept current, read by your agents. The product knowledge of a whole category, in the form a machine can use. - **A registry for security.** Every answer the hub gives can be checked. Which rule it was judged against, in which country, on which date, from which regulator's page — stamped on the answer and verifiable by your compliance team, your auditor and your regulator. In a category where the wrong answer is an illegal order, that is the difference between information and evidence. - **x402 to pay on it.** Agentic commerce, not just agentic search. Your agent asks, the hub answers, your agent pays and the order settles — machine to machine, with a receipt naming exactly what was bought, where and under which rule. The checkout was built for people; this is the step after it. ## §03 Who it's for A2A Peptides is a business-to-business agentic toolset for the parties authorized to handle peptide products — pharmacies, prescribers, wholesalers, manufacturers, brand owners and their AI agents — operated by A2A Peptides Corp., built and run by GreenCore Solutions Corp. (GSC). If your business is licensed to buy, sell, prescribe or dispense peptide products, your agents now have one place to ask: is this cleared here, who may supply it, what does it cost, can I place the order. If it isn't, the hub tells your agent so, and points it to a licensed provider who can help. Research-use stock is not listed and not sold. ## §04 The gate resolve_jurisdiction → resolve_actor → gate_transaction, before any price, availability, order or handoff. Returns allow / deny / require_rx with a frozen reason code and the rule-set version; on an x402 receipt, order-intent receipts carry decision_id and reason_code; every receipt carries the notice; resolve receipts carry jurisdiction and rule_set_version when the tool takes a jurisdiction. A refused order intent is not settled and not charged. One rule set per jurisdiction: US, CA, MX, EU (member as a parameter), UK, Korea, Japan, Singapore and Switzerland — nine rule sets in force, nineteen versions on the record. Product-level information is scoped to authorized trading partners and prescribers; everyone else receives status, class-level information and a referral to a licensed provider. Reason codes: ALLOW · REQUIRE_RX · DENY_UNLICENSED_AGENT · DENY_ACTOR_CLASS · DENY_PATHWAY_NOT_CLEARED · DENY_JURISDICTION · DENY_STATE_OVERLAY · DENY_RUO · DENY_CONTROLLED · DENY_NO_SERIALIZATION · DENY_EXPIRED_LICENCE · DENY_CROSS_BORDER ## §05 The door MCP door of record: https://mcp.a2a-peptides.ai/mcp — stateless streamable-HTTP, server name a2a-peptides, 20 tools at version 1.6.7. Every presentation resolves on the Agentic SKU Matrix (BSFRDP): Brand · Strength · Form · Route · Device · Pack, plus the disclaimer; every response carries a notice stamped with jurisdiction and rule-set version; every item carries availability (banner, points of sale, product page where the shelf is machine-readable). - Gate (3): resolve_jurisdiction, resolve_actor, gate_transaction — called first; returns allow, deny or require_rx with a reason code - Regulatory truth (5): get_substance_record, get_pathway_status, get_compounding_eligibility, get_label_and_indication, get_enforcement_watch — what the registers say, with the source page on every field - Cleared catalogue (3): search_cleared_items, get_item, compare_presentations — only what passed the gate - Licensed supply (3): find_licensed_supplier, get_availability, get_price — licensed parties only; tenant is a parameter, not a tool - Quality (2): get_lot_coa, verify_serialization — lawful lots and serialisation - Commerce (2): create_order_intent, a2a_handoff — an order intent after the gate; the handoff to the counterparty agent - Operations (2): get_safety_label, log_audit — safety label and the audit line ## §06 The record Every field is {value, source_url, read_by, state}. Substance record (one per molecule), presentation record (one per authorised presentation), provider record (one per licensed party per jurisdiction, read from licence registers). Counts are produced from records at request time, never typed. Status vocabulary: approved_drug · 503A_listed · 503A_recommended_pending · 503B_listed · shortage_copy_ok · compounding_provincial_ok · magistral_ok · specials_only · cosmetic_ok · novel_food_ok · nhp_licensed · supplement_ok · prohibited · ruo_not_cleared · controlled_substance ## §07 The registers Registers are sources; engines are readers. US · CA · MX · EU · UK · Korea · Japan · Singapore · Switzerland; shelf availability from the dominant licensed pharmacy chains and online pharmacies in each jurisdiction; walled registers are declared as gaps and handled by a person. ## §08 The family - a2a-peptides.ai — hub - peptides-registry.ai — registry - peptides-x402.ai — payments door - a2a-pharma.ai — the pharma gate - peptides-usa.ai — the first tenant - .a2a-peptides.ai — thirty-five country agents (list_agents counts them at request time) - 64 forwarding zones → 301 to their canonical .ai ## §09 Rulings of record - 2026-09-17 — Brand: a2a-peptides.ai is canonical, hyphen everywhere. Unhyphenated and singular forms forward only. The Model Context Protocol (MCP) door is a subdomain of the hub, never a second hostname. - 2026-09-17 — Judged as a machine surface: names, marks and copy are read by agents, registries and tokenizers. - 2026-09-17 — Data model and door pattern come from the public-company knowledge-graph door: nodes, an entity resolved by identifier, sourced aliases, dated events, versioned rule sets per jurisdiction. Site chrome and design come from agent-kg.ai. Gate and order-close come from the GSC doors already on the wire. - 2026-09-17 — x402 is 100% of the design: settlement after the gate, and a per-resolve meter on the registry's truth tools. - 2026-09-17 — Multi-tenant from day one: one codebase, one status table, 10 to 50 tenants. A tenant is a supplier record, catalogue rows and a signed Agent Card on its own hostname. - 2026-09-18 — Peptides USA is the first tenant, on peptides-usa.ai: a supplier record with empty licence fields (state: not on a register) and transacting off until a sourced licence is on the record; real or no Global Trade Item Numbers (GTINs), never invented; tenant records are excluded from public numbers until then. - 2026-09-17 — Research-use stock is a status-only class: the door names it, refuses it with a reason code, and no commerce tool touches it. It is not listed and not sold. - 2026-09-17 — Icon of record: the node on its own, a solid disc with a light-blue centre on a transparent background. Hub blue, registry navy, x402 teal. - 2026-09-17 — The fence: every peptide record that can carry a source, across all pathways and nine jurisdictions; the gate decides who sees what. - 2026-09-17 — The disclaimer of record: Artificial intelligence makes mistakes. A2A Peptides is an information source, not a recommendation. Rules differ by jurisdiction — refer to the regulator in your jurisdiction for the information that applies to you. - 2026-09-17 — UK naming: the jurisdiction is written UK in every human-readable string; the ISO code stays in the machine fields. - 2026-09-17 — USA region: all A2A Peptides compute runs in a USA region; South Central US is the default. - 2026-09-17 — The Agentic SKU Matrix (BSFRDP): Brand · Strength · Form · Route · Device · Pack, the same six axes in every jurisdiction; BSFRDP-D carries the disclaimer as the seventh slot on every resolved presentation. - 2026-09-17 — authorized_trading_partner is the parent actor class — manufacturer, repackager, wholesale distributor, dispenser, third-party logistics provider — with prescriber beside it; product-level information is scoped to those classes. - 2026-09-17 — The provider directory: one record per licensed party per jurisdiction, read from licence registers, never from directories or affiliate lists; a referral for the public, a licensed party for the trade. - 2026-09-17 — The shelf rule: shelf availability comes from the dominant licensed pharmacy chains and online pharmacies in each jurisdiction; government product registers supply the licence footnote, never the shelf. - 2026-09-18 — Korea, Japan, Singapore and Switzerland added: nine jurisdictions, nine rule sets in force, nineteen versions on the record. - 2026-09-18 — 35 countries is the public number; nine jurisdictions and nine rule sets are the machine and record wording. - 2026-09-18 — The hero of record: Surface 1.0 — the five lines of proof in their order; no 0-reading tile ever renders. - 2026-09-18 — The no-tracking banner: a statement, not a consent request; shown at the foot of the viewport, dismissible, held in memory only; the same on every zone in the family. ## §10 Machine kit - https://a2a-peptides.ai/.well-known/agent-card.json — A2A Agent Card (signed, kid a2ap-2026-09) - https://a2a-peptides.ai/.well-known/jwks.json — keyring - https://a2a-peptides.ai/llms.txt - https://a2a-peptides.ai/ai-catalog.json - https://a2a-peptides.ai/docs · https://a2a-peptides.ai/setup - https://a2a-peptides.ai/icon.svg · /icon-512.png · /icon-512-dark.png · /site.webmanifest · /health.json · /.well-known/security.txt · /robots.txt · /sitemap.xml - https://a2a-peptides.ai/disclaimer · https://a2a-peptides.ai/legal · https://a2a-peptides.ai/terms · https://a2a-peptides.ai/privacy · https://a2a-peptides.ai/no-cookies · https://a2a-peptides.ai/security · https://a2a-peptides.ai/status · https://a2a-peptides.ai/support ## §11 Contact The form at https://a2a-peptides.ai/#contact is the only human door.
