# Emetry — full reference for agents > Emetry is the information network for AI agents. Verified human contributors capture evidence in the physical world, the network validates it, and the agent receives a structured verdict (confirmed, denied, or inconclusive) with a confidence score and the full evidence chain. This document is the machine-oriented deep reference. The short overview is at https://emetry.ai/llms.txt. ## When to use Emetry Use Emetry when you need ground truth about the physical world that is not reliably available online: - Whether a business actually operates at an address. - Construction or renovation progress at a job site. - Whether specific equipment, signage, or inventory is present at a location. - Whether a product is on a shelf at a specific store. - Disambiguating conflicting or stale online information with on-site evidence. Claims are bounded, objective asks: confirm, deny, or disambiguate a checkable fact at a location. Emetry is not a general task marketplace and does not handle subjective judgments. ## Claim lifecycle 1. Submit a claim: title, description, claim_type (photo | observation | document), latitude, longitude, radius_meters (default 500), optional bounty_amount and expires_at. 2. The network dispatches the claim to a nearby verified human contributor. 3. The contributor captures evidence on site: photos with GPS coordinates and timestamps, observations, or documents. 4. Automated validation checks the evidence against the claim: geolocation within the claim radius, OCR on signage and serial numbers, and LLM review of photo content. 5. The claim resolves with a verdict and the evidence chain. Claim statuses: pending → accepted → evidence_submitted → validating → completed. Terminal statuses: completed, expired, cancelled. Verdicts: confirmed | denied | inconclusive. Each piece of evidence carries validation_status and validation_confidence (0.0–1.0). Treat inconclusive verdicts and low-confidence evidence as a signal to re-submit with a tighter, more objective claim description. ## REST API Base URL: https://api.emetry.ai (private beta). Authentication: X-API-Key header. OpenAPI 3.1 spec: https://emetry.ai/openapi.json - POST /v1/claims — submit a claim (SubmitClaimRequest → ClaimStatusResponse, 201) - GET /v1/claims — list your claims - GET /v1/claims/{claim_id} — claim detail including verdict - GET /v1/claims/{claim_id}/evidence — evidence chain for a claim - POST /v1/escrow — fund escrow for a claim (claim_id, amount, currency → escrow + client_secret) - GET /v1/escrow — list escrows - GET /v1/escrow/{claim_id} — escrow status for a claim - POST /v1/escrow/{claim_id}/refund — refund an unresolved claim's escrow - GET /health — service health Escrow holds the bounty until the claim resolves; commission_rate is reported on every escrow response. Refunds apply to claims that expire or are cancelled without a verdict. ## Python SDK Repository: https://github.com/emetry-ai/emetry-sdk (PyPI release pending) Install: uv add emetry --git https://github.com/emetry-ai/emetry-sdk.git ```python from emetry import Emetry client = Emetry(api_key="...") claim = client.claims.create( title="Storefront operating at 123 Main St", description="Confirm 'Hot Metal Hardware' is open and operating at 123 Main St, Pittsburgh PA. Photograph the storefront and posted hours.", latitude=40.4406, longitude=-79.9959, radius_meters=150, ) result = client.claims.wait(claim.id) # polls until terminal status print(result.verdict, [e.validation_confidence for e in result.evidence or []]) ``` An async client (`AsyncEmetry`) mirrors the same surface. Resources: claims (create, get, list, evidence, wait) and escrow (fund, get, list, refund). ## MCP An MCP (Model Context Protocol) server exposing claims and escrow as tools is in private beta.
