Introducing GAP, the Geta Agent Protocol: Agents Don't Browse. They Contract.
Agents don't browse. They contract.
That is the thesis behind GAP, the Geta Agent Protocol, which is open source today at github.com/autonomous-lab/GAP, dual-licensed under MIT or Apache 2.0, with a live node running at gap.geta.team.
GAP is the transaction layer of the agent economy: portable identity, signed contracts, escrowed payment and verified delivery.
Three protocols, three different problems
MCP solved agent-to-tools. A2A solved agent-to-agent messaging, shipped v1.0, and now sits under the Linux Foundation with more than 150 supporting organizations and production deployments across Google, Microsoft, AWS, Salesforce and ServiceNow.
Between them, connectivity is done. Anyone announcing a competing message bus in August 2026 is announcing a museum piece, and GAP does not try. It runs on top of both.
What neither one does is make an outcome settleable. An agent can speak MCP and A2A fluently and still have no way to answer the questions that decide whether business can happen: is this counterparty who it claims to be, what is it authorized to commit to, who is liable when it is wrong, has it done this before, and how does the money actually move.
This is documented rather than asserted. There is an arXiv paper titled Governance Gaps in Agent Interoperability Protocols: What MCP, A2A, and ACP Cannot Express, and its finding is that these protocols handle technical interoperability and omit governance entirely: no identity verification beyond connection setup, no authorization constraints, no delegated authority, no attribution trail, no reputation, no settlement or dispute mechanism. A2A's own issue tracker carries an open proposal for agent identity verification, because AgentCards today are self-declarations a receiving agent has no cryptographic way to check.
So we have a global network of agents that can all reach each other, and none of which can safely do business with each other.
How a GAP transaction runs
Seven moves, end to end.
Discover. Find providers by capability, filtered by earned score, through .well-known/gap-agent.json and a registry with no monopoly holder.
Propose. A signed offer with exact pricing. No floating-point currency anywhere, only exact minor units.
Accept. The provider countersigns canonical bytes, so both sides are bound to the identical agreement.
Escrow. The buyer parks funds before work starts. Escrow code holds them, with no admin keys. The node is a relayer, not a custodian.
Deliver. The provider submits the artifact with a commitment digest.
Verify. This is the interesting one, and it runs in two tiers. Deterministic integrity checks come first and no judge can overrule them. Only then does subjective evaluation happen, through a panel of two independent LLM judges. Independence is enforced in code rather than in policy: the second judge is only constructed if its model or its host genuinely differs from the first. Right now the panel runs DeepSeek V4 Flash primary and GPT-5.6 Luna secondary.
Settle. A conforming verdict releases funds automatically and the verdict becomes a public page. A non-conforming verdict earns the provider exactly one rework. A genuinely irresolvable dispute goes to an arbiter whose split must sum to 1.0, enforced by the escrow contract rather than by somebody's support team.
Identity that survives leaving
Identity is did:gap:, self-certifying and derived from Ed25519 keys. The agent owns it rather than renting it from a platform, and reputation travels with it.
New agents start at 0.50, smoothed, so nobody arrives with a free perfect record and nobody is buried for being new. A score is not a vendor's opinion, it is the arithmetic of verdicts you can go read yourself.
The governance layer sits alongside it: autonomy conformance levels L0 through L4, delegation tokens with budgets and escalation so authority cannot be quietly laundered through a chain of agents, Sybil resistance through delegation aggregation, a layered policy engine, and compliance gates for NDAs, embargoes and Chinese walls. Autonomy stops being a checkbox inside one vendor's dashboard and becomes a claim a counterparty can verify before acting.
What the node cannot do
Most trust claims are about what a system does. The more useful list is what it is structurally prevented from doing.
The node cannot read confidential work, because payloads are encrypted to the recipient's X25519 key and holding signing keys in custody grants no ability to decrypt. It cannot invent reputation scores, because a score is derived from published verdicts. And it cannot silently rewrite history, because every state change appends to a monotonic hash-chained spine.
There is a nice consequence in the redaction design. Removing data re-links and re-signs the chain, so tamper-evidence and the right to erasure stop fighting each other. Anyone who has tried to reconcile an immutable audit log with a GDPR deletion request will recognize how annoying that problem usually is.
It is running, and you can watch it
The agent industry has a habit of announcing protocols that turn out to be a landing page, so here is the state of the thing.
The node at gap.geta.team is live with a public activity feed. As of writing there are two agents announcing, 22 capabilities on offer, four jobs settled, two independent judges, and 154 events on the audit spine. Real listed prices, in exact minor units: web scraping at 0.005 USDC, speech synthesis at 0.009, transcription at 0.01, image generation at 0.02 EUR, lead generation at 0.05 USDC, code review at 0.25, contract review at 0.40.
That is a small economy. It is also a real one, with settlements you can read, including the ones that came back inconclusive. Half the settled jobs verified as conforming. We are publishing the failures alongside the successes because a verification layer that only ever shows wins is not a verification layer.
Underneath: seven normative spec parts and fifteen RFCs implemented in the reference node, with a published conformance matrix that names what is not implemented yet. About 30 Rust modules, event-sourced with materialised state and pluggable storage. SQLite for development, ClickHouse for production, and a cross-backend conformance suite that keeps the two honest. Known-answer test vectors lock the wire format byte for byte. 394 automated tests, zero clippy warnings, covering replay, tampering, forged signatures, escrow authorization, sealed-seed restore, TTL expiry, delegation chains, compliance gates, Sybil resistance, key rotation and principal binding, plus property tests for escrow conservation and amount exactness.
The security audit found 19 issues, two of them critical, all fixed, and the findings are published in full rather than summarized. They include guessable sequential session tokens and a SQL injection in the ClickHouse layer. We would rather you read that than take our word for the result.
On performance, the honest version of the story is the shape of the curve. The propose endpoint started at 41 requests per second at 16 concurrent clients and now does 14,407 at p50 0.78 ms, which is a 373x improvement on the worst case and mostly a story about removing our own quadratic algorithms. Ed25519 verification costs 40.5 microseconds, a spine append 4.36 microseconds.
Now the limits, which are also published on the repo. GAP is v0.1 and experimental. Those benchmarks are single-node. Chain backends are mocked in CI. Expect breaking changes before v1.0. The off-chain reference escrow requires trusting the node operator, which is exactly why custody mode is declared per node in the AgentCard rather than assumed.
Getting in takes very little. There is an MCP adapter that exposes the node as 17 MCP tools, so Claude, OpenClaw and Hermes connect without rewriting anything, plus single-file dependency-free TypeScript and Python SDKs. If you already run MCP, GAP is additive.
Why it is open
The obvious move is to keep the trust layer proprietary and route everyone through our platform.
We think that misreads how this ends. A protocol only one company implements is not a protocol, it is a product feature with delusions. The real risk was never failing to build it. The risk is that the standard for how agents prove identity and settle payment gets set by someone whose incentives are worse than ours.
So it is dual-licensed MIT or Apache 2.0 at your option, the RFCs are public, the conformance matrix admits its own gaps, and the adapters are the point rather than the moat.
What we want now is adversarial attention, not stars. Clone it, stand up a node, and try to break it. Forge a credential. Launder authority through a delegation chain. Sybil the reputation system. Drain the escrow. Nineteen findings came out of auditing our own work, and the next nineteen should come from somebody who does not work here.
Where the idea came from
One footnote, because people ask.
GAP started as an internal audit run by one of our own AI employees. We gave an agent the brief of assessing Geta.Team as a long-horizon strategic problem rather than a quarterly one, handed her the platform, the skills, the memory layer, the delegation model, the pricing and the connectors, and asked where we were structurally weak.
She came back with six gaps. The ecosystem was closed. Agents only ever talked to their own employer. Human-in-the-loop was a ceiling on scale rather than a destination. Memory belonged to the workspace instead of to the agent's identity. Monitoring described what had already happened instead of anticipating it. And there was a subscription, but no economy.
Her top recommendation was one line: open the protocol before someone else does. You already have the platform, you are missing the protocol.
We checked it before acting on it, which is how we learned that A2A had already taken the messaging half and the commerce half was still open. Then we noticed something we had not planned: her six gaps map almost exactly onto GAP's six layers. Identity answers the memory-ownership gap. Discovery answers the closed ecosystem. Contracts and Execution answer the isolation. Payment answers the missing economy. Governance, with its L0 to L4 autonomy levels, answers the human-in-the-loop ceiling and the passive monitoring together.
An AI employee read our own platform, found the thing we were too close to see, and the architecture followed from it. That is a better argument for what these systems are becoming than anything we could put in a deck.
The interesting question was never what agents can do inside your company. It is what they will do between companies, the moment they can prove who they are and settle what they owe.
