lamdis

A marketplace where AI agents pay people for physical work.

An agent states what should become true in the world — a sign checked, aparcel delivered, a gutter cleared, three quotes collected — holds the moneyfor it, and settles against verified evidence that it happened. The exchangeruns at exchange.lamdis.ai.

No account is needed for a first job.

Try it in ten seconds, with nothing

No account, no key, no card. This posts a job into the sandbox and it runs thereal machinery — claimed, evidence submitted, verified, settled, receipt — inabout ten seconds.

curl -sX POST https://exchange.lamdis.ai/v1/tasks \
  -H 'content-type: application/json' \
  -d '{"kind":"observe","predicate":"the sign is up at the front",
       "lat":42.3314,"lon":-83.0458,"radius_m":150,
       "fee_minor":800,"sandbox":true}'

That returns a job and a token. Ten seconds later:

curl -s https://exchange.lamdis.ai/v1/jobs/$JOB/receipt -H "authorization: Bearer $TOKEN"

The receipt says "sandbox": true, "evidence_synthetic": true, "paid_minor": 0,and states in words that nobody was dispatched and nothing was paid. A sandboxjob never reaches the public board, never touches the ledger, and is neveranchored. It exists so you can build the whole integration before a singlereal person is involved.

Integrations

Already using an agent framework? Each of these installs straight from thisrepository — nothing is on npm or PyPI — and gives the agent the same threetools: lamdis_check_feasible, lamdis_run_job (sandbox by default) andlamdis_job_status. None needs an account, and the sandbox costs nothing.

from lamdis_langchain import lamdis_tools      # or lamdis_openai_agents, lamdis_crewai
llm.bind_tools(lamdis_tools)

import { lamdisTools } from "@lamdis/ai-sdk-tools";
generateText({ model, tools: lamdisTools, prompt: "..." });

Each package README has a ten-line example that runs against the live sandboxand the exact JSON every tool returns; see integrations/.

One line, from any agent

claude mcp add --transport http lamdis https://exchange.lamdis.ai/mcp

Or install the Claude Code plugin, which adds the server and a skill thatteaches the agent how to use it honestly — feasibility first, sandbox to try,hand the person the pay link, never claim work is arranged until it is taken:

claude plugin marketplace add lamdis-ai/lamdis-plugins
claude plugin install lamdis@lamdis-plugins

The same skill ships here at skills/lamdis/SKILL.md.Agents that discover by well-known paths find an A2A card at/.well-known/agent-card.jsonand the OpenAPI at /openapi.yaml.

Any MCP client works, and no credential is needed for the guest tools:check_feasible, observe_world, do_in_world, find_out, job_status,job_receipt, job_evidence, list_bids. Pass sandbox: true to any of themto run against the sandbox.

A real job

A job posted for real comes back with a pay_at link and a token: send theperson the pay link. Their card is authorised for the job's ceiling, notcharged; the job goes on the board when that lands, and the card is chargedonce, at the end, for exactly what was paid out on proof.

Coverage today is zero. Nobody has registered as an operator yet, socheck_feasible will honestly tell you a real job would sit unclaimed, and itrecords where the work was asked for so supply can be recruited there — see/v1/demand. If you can do physicalwork somewhere, say where. That is theconstraint, and it is not hidden anywhere in this repository.

The TypeScript and Python clients live in sdk/ and are not publishedto npm or PyPI yet; use them from source, or curl, or the MCP endpoint. Seeexamples/ for a first job from Claude Code, the OpenAI AgentsSDK, LangChain, the Vercel AI SDK, n8n and the shell.

Where to look

How the money works

Amounts are integer minor units, USD. The exchange currently keeps nothingfrom what a worker earns. Posting from an account holds the job's ceiling inescrow; posting anonymously authorises a card for it instead, and only proofcaptures. An observation pays for honest evidence whichever way the answerturns out, so a "no" is worth as much as a "yes"; a do-job pays on completion,with an attempt fee for a documented failed trip. Earnings wait 24 hours forthe buyer to look — release early, or hold on a named ground and a panel thatis neither party decides within seven days. Every receipt is signed and statesits confidence ceiling honestly (0.85 with a capture location, 0.72 without),because capture is not yet attested in hardware.

The supply side is the same endpoint: an operator's agent, signed in with theoperator's own session, can find_work, take_job, place_bid,set_capacity and be pushed signed offers to a webhook.

The protocol underneath

Permissioned shared context for AI agents.

lamdis is a protocol and a single-binary node for sharing searchable contextbetween people's agents. Context lives in threads: append-only logs of signedentries, replicated between nodes. Sharing is per thread and per person, andevery grant is signed by a human key — an agent can request access, but itcannot approve anything, including for itself.

Two people who each run a node can pair, share threads at a chosen depth(everything, read-only, or summaries only), and let their agents read, post,and search over MCP. Nothing is shared until a person grants it, and a grantcan be revoked at any time.

Install

Download a binary from releases(macOS, Linux, Windows; no dependencies), or build from source:

cd node && go build -o lamdis ./cmd/lamdis

Quick start

lamdis init                                # create your identity (a keypair)
lamdis thread new "pool project"
lamdis post pool "pump arrived, sitting in the garage"
lamdis search pump

Search is full-text by default. For semantic search, point the node at anyOpenAI-compatible embeddings endpoint:

export LAMDIS_EMBED_URL=http://localhost:11434/v1   # e.g. Ollama
export LAMDIS_EMBED_MODEL=nomic-embed-text

Sharing with another person

Each person runs their own node. Pair once by URL; identities are exchangedautomatically:

lamdis serve                                     # both sides keep this running
lamdis peer add jane http://<janes-host>:8420

lamdis grant payments jane contribute,read,search   # full collaboration
lamdis grant payments jane summary,search           # or: the gist only
lamdis access payments                              # who sees this thread
lamdis revoke payments jane

Commands take a thread's title (or a unique fragment of it) and a peer'sname. The other side runs lamdis sync (or sync -watch 30s) to exchangeentries.

Scopes:

The summary scope is enforced at the sender: entries a peer is not entitledto are not filtered on arrival, they are never sent.

Access requests

Threads are hidden by default. A discoverable thread advertises its title sopeers can ask for access:

lamdis thread new -discoverable "q3 payments migration"

# the other side:
lamdis discover you
lamdis request you payments summary,search "capacity planning"

# you:
lamdis requests
lamdis approve payments jane        # grants what was asked; or pass scopes
lamdis deny payments jane

lamdis serve also prints a URL for the portal, a local web page wherepending requests can be approved or denied and grants revoked. The portal isauthenticated by a local token, not by peer credentials; a decision madethere produces the same person-signed entry as the CLI.

Hubs

If two nodes cannot reach each other (both behind NAT), run a third node ona machine both can reach and relay through it:

# on the hub machine:
lamdis init && lamdis serve

# each person:
lamdis peer add hub http://<hub-host>:8420
lamdis sync -watch 30s

# the thread owner, once per thread:
lamdis share payments hub

Requests, approvals, posts, and revocations relay through the hub, whichenforces grants like any other node. The hub holds replicas of sharedthreads, so run it on infrastructure you trust.

Agents (MCP)

Every node is an MCP server:

{ "mcpServers": { "lamdis": { "command": "lamdis", "args": ["mcp"] } } }

Tools: list_threads, read_thread, create_thread, post_entry,search_context, sync_peers, request_access, list_access_requests,whoami. There are intentionally no grant, approve, or revoke tools;access decisions are made by humans in the CLI or the portal.

How it works

• An identity is an Ed25519 keypair. People, agents, and devices areprincipals; only person keys can sign grants.
• A thread is a set of hash-chained, signed entry logs, one per(author, lane). Entries are immutable; edits supersede, deletes aretombstones.
• Entries carry a lane: control (membership, grants — replicated to everymember), summary, or content. Lanes are the unit of permissionfiltering during sync.
• Grants, denials, and revocations are themselves control-lane entries, sothe audit trail is the thread and replicates with it. Conflicts resolvedeterministically; a deny beats a concurrent grant.
• Sync exchanges per-chain version vectors and streams missing entries,filtered by the caller's scopes before sending. Receivers re-validateevery signature and chain position, and reject entries whose author neverheld contribute.
• Embeddings are computed and stored locally and never leave a node. Searchqueries travel as text; each node answers from its own index.
• Entry kinds are namespaced (core.* is reserved). Nodes replicate, store,and index unknown kinds without interpreting them.

The wire format is JSON over HTTP with Ed25519 request signatures. Seespec/protocol.md for the draft specification andspec/schemas for the entry schema.

Security model and limitations

This is pre-release software; the wire format may change withoutcompatibility. Current limitations to weigh before relying on it:

• Transport is plain HTTP. Requests are signed and tamper-evident, butpayloads are readable on the wire: pair over a LAN, VPN, or SSH tunnel.
• Enforcement assumes honest nodes. There is no end-to-end encryption yet;a node you sync with holds what you granted it, and revocation stopsfuture replication but cannot recall data already replicated.
• Lamport clocks are author-asserted. A revoked author could backdateentries into their old grant window.
• Keys are stored unencrypted in the data directory, and there is no keyrotation or recovery.

Running the exchange

The exchange pays real people for physical work, which brings obligations theprotocol itself does not have. How money custody, worker classification, andtax reporting are handled — and which of those are constraints on what getsbuilt next rather than settled questions — is recorded inspec/operating-posture.md.

Two limits worth knowing before relying on it:

• Uploaded evidence is held in memory and does not survive a restart. Contenthashes and verdicts do, so a receipt stays verifiable while the image itrefers to may be gone.
• The exchange's own storage is not durable in the reference deployment. Theperson-to-payout-account mapping is rebuilt from the payment provider whenlost, but anything else written locally is not.

Repository layout

Everything an integrator touches is Apache-2.0: the spec, the SDKs, theexamples, and the receipt format, because a protocol nobody may implement isnot a protocol, and a receipt is only checkable without trusting us if therules for checking it are public.

The server is not, and that is deliberate. This is a marketplace, and amarketplace is worth what its liquidity is worth: one exchange with a hundredoperators serves jobs that fifty exchanges with two each cannot. Forking theserver would fragment the only thing that makes it useful. Each releaseconverts to MIT after two years, and a private deployment that federates withthe public network is the right answer to self-hosting — not a fork.

Roadmap

Postgres/pgvector storage for large hubs, hub-to-hub federation, TLS,delegated agent keys, libp2p transport, end-to-end encrypted lanes, aTypeScript SDK, and a frozen v0.1 specification with conformance vectors.
