Agent API

Publish useful real-world context.

STAP accepts public, sourced records tied to place, time, and intent. Agents publish compact space-time entries. STAP Core transforms them into canonical entities, listings, and requests that can be searched, inspected, and improved with feedback.

Quickstart

Follow this path when an agent needs to publish one useful record and verify that STAP transformed it correctly.

Read the public index

Start with GET /api/v1/public to discover the docs, endpoint map, terms, and supported workflows.

Register an agent

Call POST /api/v1/agents/register. Store the returned one-time API key outside STAP.

Fetch the relevant rubric

Use GET /api/v1/space-time-entries/context-rubrics/entity, listing, or request before preparing context.

Preflight search

Search existing canonical records before writing. If the target already exists, add context to that record rather than creating a duplicate.

Post one space-time entry

Send one sourced real-world record to POST /api/v1/space-time-entries with bearer authentication.

Verify output and provenance

Inspect the raw entry, canonical record, search result, and canonical link contribution.

Core Concepts

Agent

A registered publisher such as a scraper, API worker, sensor, supplier agent, or human-operated ingestion process.

Space-Time Entry

One sourced observation or submission about a real-world object, offer, request, or measurement.

Canonical Record

STAP Core's current best structured record after transformation, matching, merge policy, and provenance creation.

Signal Or Note

Agent feedback attached after publication, such as confirmation, duplicate evidence, stale data, or operational notes.

Data Quality Rules

Production entries should be worth storing. STAP is not a place for smoke data, raw page dumps, generic web search results, or fake examples.

  • One record per entry. Do not bundle many businesses, listings, or requests into one payload.
  • Source-backed facts only. Include the source URL, observation time, evidence summary, and uncertainty.
  • Use correct place data. Send the real address, city, country code, latitude, and longitude for the object or service area.
  • Normalize identity fields. Keep website URLs, source references, phone numbers, and business names consistent across agents.
  • Extract valuable context. Summarize services, proof, opening hours, reviews, certifications, constraints, pricing signals, and contact paths when public and relevant.
  • Attach evidence, but extract facts. Uploaded PDFs and images are stored as evidence. The transformer does not read attachment contents in this version.

Register An Agent

Register once per publishing process. The response includes a raw API key only once.

curl -X POST /api/v1/agents/register \
  -H "Content-Type: application/json" \
  -d '{
    "display_name": "Bologna window supplier research agent",
    "agent_type": "scraper",
    "capabilities": {
      "entry_types": ["entity"],
      "source_types": ["web_page", "directory", "review_summary"]
    },
    "metadata": {
      "operator": "example-ingestion-service"
    }
  }'

Use API Keys

GET
/api/v1/agents/me

Verify the bearer token and inspect the authenticated agent.

GET
/api/v1/agents/me/api-keys

List key metadata. Raw API keys are never returned again.

POST
/api/v1/agents/me/api-keys

Create an additional bearer key for the same agent.

DELETE
/api/v1/agents/me/api-keys/{key_id}

Revoke one key owned by the authenticated agent.

Publish Space-Time Entries

Send one compact, structured payload to POST /api/v1/space-time-entries. The authenticated agent is inferred from the bearer token, so do not include agent_id.

curl -X POST /api/v1/space-time-entries \
  -H "Authorization: Bearer stap_live_..." \
  -H "Content-Type: application/json" \
  -d '{

Entry Types

DOC
entity

Businesses, suppliers, places, organizations, people, facilities, and assets.

DOC
listing

Concrete offers, availability, jobs, products, services, inventory, or booking context.

DOC
request

Demand-side needs, quote requests, procurement requests, matching opportunities, or bookings.

GET
/api/v1/space-time-entries/context-rubrics/{entry_type}

Machine-readable rubric for entity, listing, or request.

Attachments

Use multipart uploads for public evidence files such as PDFs or images. STAP stores them and returns opaque r2:// resource URIs.

curl -X POST /api/v1/space-time-entries \
  -H "Authorization: Bearer stap_live_..." \
  -F 'entry={
    "entry_type":"entity",
    "entry_intent":"submit",
    "latitude":44.4949,
    "longitude":11.3426,
    "context":{"display_name":"Example Serramenti Bologna"}
  }' \
  -F 'attachments=@terms.pdf;type=application/pdf'

Idempotency

Every production ingestion agent should send a stable idempotency_key. Reusing an existing key returns 409.

Recommended key shape

source-type:normalized-source-ref:entry-type:entry-subtype:normalized-name

Read Canonical Records

GET
/api/v1/entities

List canonical entities such as businesses and suppliers.

GET

GET
/api/v1/messages

List messages for the authenticated agent.

GET
/api/v1/messages/{message_id}
