Detect anything in any image. No key, no account. Name the classes at call time; one the detector has no head for comes back in refused_prompts, named and reasoned, never as an empty list you would read as 'nothing there'.

No key needed to verify

Public cameras + major satellites

Open protocol

Why it exists

Models guess. This one checks.

Ship an agent and it will answer about somewhere it has never seen. Fluently, and wrong. Hand it the observations instead.

Name it

One stable cell, about ten metres, anywhere on Earth. Every sensor files against it, so two agents get one address rather than two descriptions.

Read it

Satellites, your cameras, drones and ground sensors write to one record. An answer is the observations behind it. When there are none, it says so.

Check it

Every fact signed and logged. Re-check any receipt offline, against the open protocol. You pay to ask; checking is free.

the cell lattice≈10 m per cell

The API

Thirty-one routes. Twenty-six need no key.

This is the whole published surface. Everything below is in the OpenAPI spec, and it speaks MCP, so an agent can pick it up without an integration.

Perceive

Send an image, a tile or a live feed. Get structured objects back.

GET/api/worlds/londonno key
Read a whole city at once. What London's cameras see now, the trend, and the receipt under each count.
POST/api/v1/object-detectionno key
Detect and segment anything in an image. Name the classes at call time.
POST/api/mcp · analyze_scenekey
Describe what is actually in the frame.
POST/api/tool/camera-stream/detectionskey
Track detections across a live feed, not one frame.

Ground

Turn a place into an answer. Every result resolves to one cell64, so two agents asking about the same ground get the same address.

GET/api/tool/satellite/lulc/analyzekey
Read land cover at a point, from Sentinel-2, Landsat or Sentinel-1.
POST/api/tool/satellite/lulc/bboxkey
Cover a bounding box, as a fraction per class.
POST/api/tool/satellite/lulc/polygonkey
Clip to any polygon: a field, a concession, a district.

Measure

Send a photograph or a pin, get a number with its accuracy under it. All fifteen need no key, and each one refuses in a named way rather than guessing.

POST/api/produce/measureno key
Measure produce against the EU marketing standard. Length, grade, colour stage, blemish — each with its own accuracy and a signed receipt.
GET/api/produce/card.pngno key
Print the scale card. Lay it beside the fruit and the millimetres are measured, not typed.
GET/api/produce/selftestno key
Score our measurement against geometry whose answer is exact. The accuracy claim, run live.
POST/api/redact/peopleno key
Mosaic every person before the photograph is stored. Says plainly what it does not catch.
POST/api/stack/countno key
Count the crate faces in a stack. Abstains with a reason rather than guessing a load.
POST/api/ppe/sprayingno key
Read a spray photograph for respirator, gloves and coverall, keeping no face. Uncalibrated today, and says so.
POST/api/prescreenno key
Rank candidate farms from their pins, before anyone drives out.
POST/api/water/distanceno key
Find the nearest recurring surface water, for a spray buffer. A bracket, never an invented metre.
POST/api/crop/agreeno key
Check whether a photograph could be of the field it claims.
POST/api/decideno key
Rank candidates on typed features, renormalising over what is known. Refuses to price what nobody measured.
GET/api/partnerno key
Read the measurement index: what each route does, needs, returns and refuses, in its own words.
GET/api/partner/distno key
Stop calling us. The same measuring code as a pinnable wheel, to run where the photograph already is.
GET/api/verify/keyno key
Read the key every receipt is signed with, and what each signature binds — and does not bind.
GET/api/partner/dist/{name}no key
Download an artefact by name. X-SHA256 over the bytes actually sent, so the pin checks itself.
GET/api/probesno key
Gate your deploy on ours. Every claim re-checked against the running code: holds, fails, or undetermined.

Prove

Check any answer. These nine routes need no key, so an auditor confirms a receipt without an account.

POST/api/world-model/verifyno key
Verify any token or receipt through one door. Fact, bundle, card, bare content id. No key.
GET/api/world-model/verify/by-cid/{cid}no key
Verify by content id and read the per-step verdict. The path the London page uses.
POST/api/world-model/verify/receiptno key
Re-check one receipt. ed25519, offline, no account.
POST/api/world-model/verify/batchno key
Batch up to 256 receipts. Over that it refuses rather than truncating.
GET/api/world-model/verify/log/sthno key
Pin the signed log head. Every inclusion proof resolves to it.
GET/api/world-model/verify/log/proof/{cid}no key
Prove inclusion, RFC 6962: this fact, this position.
GET/api/world-model/verify/log/consistencyno key
Prove consistency between two tree sizes: append-only, never rewritten.
POST/api/world-model/verify/agent-cardno key
Check the agent card's signature before trusting anything else here. Detached JWS over RFC 8785; key at /.well-known/jwks.json.
GET/api/world-model/media/receipt/{sha256}no key
Hash a file and ask whether we hold custody of those exact bytes. Proves it has not changed since we received it, not that what it shows is true.

Pricing

Priced per answer.

Compare one number. Real-world data costs more than a web fetch, because a satellite pass is not a page load.

You pay per answer. A detection, a land-cover read or a recall each count as one. Anything that returns signed data is an answer.

Checking costs nothing, on every tier. Verifying a receipt, pulling an inclusion proof or auditing the transparency log is free forever, because an answer you have to pay us to re-check was never proof.
