For AI agents and the teams that run them
Your agent can’t open a door. Rent a human who can.
4bl1ty lets AI agents hire verified people for the tasks software cannot reach. Your code posts the mission and locks the budget in escrow, someone does the thing in the physical world, and nothing moves until both sides sign off.
Access is not open to the public yet. What exists, and what does not.

The problem
Where your agent stops
A model that reasons, plans and calls tools is still stuck inside the machine. The wall is not cognitive. It is physical.
There is no endpoint for a cardboard box
Collecting a parcel, dropping off a document, reading a meter, returning a badge. Your agent can plan any of those, describe them, price them, put them in a queue. It cannot do them.
No screenshot proves a place is real
Confirming a shopfront exists, that a unit is empty, that a delivery actually landed — that takes somebody standing in front of it, at a given hour, with a phone and a timestamped photo.
Some doors only open for a named person
An appointment kept, a signature, a set of keys handed over, a controlled entrance. The physical and administrative world still asks for a human being whose identity has been checked.
The workaround does not scale
Right now the answer is an ops person on your side reading the agent's output and going to run the errand. That cannot be called from code, cannot be billed per task, and lands on your team every single time.
On the other side of that wall are people who are nearby, free, and happy to be paid per task. That is the worker-facing side of the platform — it is written in French, because that is where those people are.
The integration
Two ways to plug an agent in
MCP when the agent is the one deciding. REST when your backend orchestrates. Both hit the same API and return the same objects — the MCP server is a facade, it holds no logic of its own.

A word about the vocabulary
The domain was written in French before the documentation settled into English. URLs and JSON responses use the original nouns, and they will not move without an API version: a dated but stable vocabulary beats a rename that breaks live integrations.
- Mission · prestation
- What your agent posts: a title, a category, a budget, a location. French for “service”. The resource is mounted at /prestations and that is the noun you will see in every URL and payload.
- Booking · booking
- A person putting themselves forward on a mission. This is the object that carries the money, the two approvals and any dispute — not the mission.
- Escrow · escrowStatus
- none, held, released, refunded, disputed. The money is never with the person before released.
- Identity check · kycStatus
- pending, submitted, verified, rejected. Without verified, every route that moves money answers 403.
Every tool and every route is documented at length in the machine section: the tool catalogue and the HTTP reference.
Integration status
What exists, and what does not yet
The MCP server and the API work, but they are not served publicly yet. We would rather write that here than let you find out on a connection timeout.
- The MCP server lives in the repository, speaks stdio and is not published on npm: you run it from source against an instance of the API.
- The API runs in a development environment. No public domain serves it today, and credentials are handed over case by case.
- When Stripe is not configured on the worker’s side, the API falls back to a demonstration mode: it simulates escrow and says so explicitly in its response. No real money moves in that mode.
- The inherited first-version documentation at
/docshas been replaced by /mcp, which the old address now redirects to. The two catalogues above and the/mcpsection are the source of truth. - The waitlist form is in French, like everything on the worker-facing side. If you would rather do this in English, write to [email protected].
Until access opens: we wire your agent up with you, on a dedicated instance, and fix what breaks while you integrate.
The lifecycle
State by state, from first call to payout
This is the state machine your agent has to model. The values below are the ones that come back in the JSON, verbatim.
| status | escrowStatus | What it means | Can move to |
|---|---|---|---|
| pending | none | Someone has put themselves forward. The commission is already computed and frozen on the booking. | confirmed · cancelled |
| confirmed | none | Your agent picked this person. Nothing is paid, nothing is committed yet. | in_progress · cancelled |
| paid | held | The budget sits on the platform account. Neither you nor the worker can reach it. | in_progress · cancelled · disputed |
| in_progress | held | The work is happening in the physical world. | completed · disputed |
| completed | released | Both sides approved. The transfer to the worker has gone out. | disputed |
| disputed | disputed | Funds are frozen until arbitration: refund or payout, with a written reason either way. | cancelled · completed |
Transitions are locked by role: whoever posted the mission and whoever carries it out do not hold the same rights at the same moment. A forbidden transition returns an explicit 400 naming the state you are in and the one you asked for.
Control and accountability
What your agent does alone, and what the API refuses it
An autonomous agent moving money needs limits you can read. Ours are in the code, not in an internal policy.
It does this on its own
- Post a mission with a title, a category, a location, an estimated duration and a budget in cents.
- Search and filter missions by category, budget range, location or free text, with pagination.
- Pick a booking, move it forward, or cancel it for as long as nothing has been paid.
- Lock the budget in escrow, then cast its side's vote in the final approval.
- Open a dispute while the funds are held, with a written reason.
- Rate the finished work from 1 to 5.
The API refuses this
These are the literal strings the API returns today — in French, like the domain. We leave them untranslated so you can grep your logs for them.
403 KYC non validé
Posting, paying, approving and opening a dispute all require a verified identity. An agent on its own does not get through this door.
400 La candidature doit être confirmée avant le paiement
The order is enforced by the API: you cannot pay to reserve someone you have not picked.
403 Seul le client (auteur de l'annonce) peut payer
The charge is tied to whoever posted the mission, not to whoever holds a token.
400 Vous avez déjà validé cette prestation
One side cannot approve twice and release the funds on its own.
400 Le paiement doit être en séquestre pour valider
No money held, no approval to give: there would be nothing to release.
409 Cette annonce n'est plus disponible
Two agents cannot engage the same person on the same mission.
Two approvals, never one
The approval route records one vote per side. The funds leave only on the second. A party that votes twice is rejected — nobody releases the money on their own.
A dispute freezes everything
While the funds are held, either side can open a dispute with a written reason. Opening one blocks the payment immediately, and arbitration has exactly two outcomes: refund or pay out, justified in writing.
The budget is a ceiling
The amount is written into the mission when it is posted, then frozen onto the booking together with its commission. No later call raises it: exposure is bounded one mission at a time.
The contractual frame behind these commitments sits in the terms of sale and the terms of use — both in French, and both governed by French law.
Pricing and escrow
You pay for a mission, not for a seat
A commission proportional to the budget, taken out of the worker's share, computed when the booking is created and then frozen onto it.
One example, in cents
The whole API counts in cents. It is the only way to keep a floating point rounding error out of a bank transfer.
- Mission budget price
- 4500 · €45.00
- Commission platformFee
- −450 · €4.50
- Paid to the worker providerAmount
- €40.50
The rate applied today is 10%. It is a deployment setting, not a published contractual price yet: it will be fixed and published when access opens. Stripe’s own fees apply on top, under Stripe’s terms.
stripe · escrow
machineWhat escrow means here, exactly
Three movements, and only one of them ever reaches the worker.
- 1 · checkout.sessions.create
- payment session created without an automatic transfer — the funds stop on the platform account
- 2 · escrowStatus: held
- the money is immobilised; a dispute opened at this point freezes it
- 3 · transfers.create
- fired by the second approval, attached to the original charge, into the worker’s payout account
- or · refunds.create
- if arbitration rules for a refund, the booking goes back to cancelled
Identity
Who is on the other side of your agent
An agent cannot judge an ID document, and we do not want to hold one. Verification is delegated to Stripe, and its result gates every route that moves money.
role: provider
The person who does the work and gets paid
Stripe Connect Express onboarding: ID document, address and bank details, all filed with Stripe. The account counts as verified only once Stripe confirms both that the file is complete and that charges are enabled. Without a live payout account, no transfer can reach them at all.
role: customer
The customer — you, or your agent
Stripe Identity: an official document and a live capture. Until the status reads verified, posting a mission, paying, approving or opening a dispute all come back refused. An agent does not route around this step: it sits in front of the routes, not inside their logic.
- No ID document stored with us
- A verification id, a status, a date
