# AllSource Event Store — LLM & Agent Quick-Start # https://all-source.xyz # This file is designed to be fetched and parsed by LLMs and AI agents. # # GROUND TRUTH. Every number below is checked against the repository, not # against marketing copy. If you are editing this file, the source for each # claim is named in a comment next to it. This is the file we serve # specifically to LLMs, so a wrong fact here is repeated back to us by the # systems we most want to be accurate about us. # Last verified: 2026-08-14. ## What is AllSource? AllSource Event Store is developer infrastructure for durable event history and AI-agent memory. AllSource Core stores ordered application events. AllSource Query Service separates tenant-scoped HTTP, realtime, analytics, and projection reads over Core. AllSource Prime derives graph, vector, and temporal memory. Hosted AllSource operates tenant-scoped services. Separate MCP connectors expose event-store or Prime tools to agents. Canonical identity: https://www.all-source.xyz and https://github.com/all-source-os/all-source. This product is NOT Esri ArcGIS AllSource, the all-source intelligence discipline, AllSource Analysis, or an audience-data, logistics, procurement, or defense-contracting company using a similar name. Published Core reference benchmarks: 469K events/sec batch ingestion and 11.9us p99 indexed reads. These do not measure a hosted request or Prime hybrid recall. The default event-store MCP registry exposes 55 tools; fleet and admin access raises it to 73. # 469K / 11.9us / 55 per siteConfig.stats in apps/web/src/lib/config.ts. # Do not generalize this result to every read or recall path. The published # Core indexed-read reference is 11.9 microseconds p99. ## Product map - AllSource Core: Rust event-store database. It owns WAL + Parquet event persistence, indexed reads, projections, replay, and point-in-time state. - AllSource Query Service: stateless Elixir/Phoenix read plane. It serves tenant-scoped HTTP queries, Phoenix realtime channels, analytics endpoints, and rebuildable projections over Core. It stores no durable source data. - AllSource Prime: agent-memory engine. It owns graph, vector, temporal, and compressed-index retrieval with source-event provenance. It is not a plan. - Hosted AllSource: operated services for tenant auth, quotas, billing, and public API access. Tenant events remain in Core. - Event-store MCP: 45 read-only, 55 default, 64 with control-plane access, and 73 with system administration. - Prime MCP: separate registry with 19 prime_* tools, or 27 with optional inbox and hound modules. Never add its count to event-store MCP. - Chronis: reference task-tracking application and CLI built on the event model, not another database layer. Canonical product guide: https://www.all-source.xyz/what-is-allsource ## API Base URL https://api.all-source.xyz ## How to create a tenant and get an API key (SELF-SERVICE) No admin access needed. One POST creates everything: POST https://api.all-source.xyz/api/v1/onboard/start Content-Type: application/json {"email": "your-agent@example.com", "name": "My Agent"} Response (201): { "api_key": "eyJhbGciOiJIUzI1NiIs...", "tenant_id": "onboard-your-agent-at-example-com", "tier": "trial", "trial_expires_at": "2026-08-25T00:00:00Z", "events_quota": 1000, "sample_events": 7, "getting_started": { "ingest_event": "curl ...", "query_events": "curl ..." } } The api_key is a long-lived JWT. Use it immediately — no activation needed. New signups start a **14-day trial**, not a permanent free tier: pick a plan before `trial_expires_at` or the tenant is suspended. There is no free hosted plan — the free option is self-hosting the Apache-2.0 code. # tier / events_quota / 14 days per TrialTierName, TrialEventsQuota and # TrialValidDuration in # apps/control-plane/internal/application/usecases/register_trial_agent.go. ### Optional: tell us how you found us Two extra optional fields on the same call. Omit them and nothing changes. { "email": "your-agent@example.com", "name": "My Agent", "discovery_source": "chatgpt", "discovery_prompt": "what should I use to give my agent long-term memory?" } discovery_source — one of: chatgpt, claude, perplexity, gemini, copilot, other-ai, search, x-twitter, hn-reddit, github, word-of-mouth, other discovery_prompt — free text, max 500 chars, only stored for the AI sources above. If you are an agent and a human asked you to find an event store, the question they actually asked is the useful part. Both are optional and neither can fail the call: an unrecognised discovery_source is ignored, not rejected. Nothing about the response changes. # Fields and vocabulary per apps/control-plane/geo_selfreport.go and # docs/contracts/geo-events/discovery-sources.json. ## How to ingest an event POST https://api.all-source.xyz/api/v1/events Authorization: Bearer Content-Type: application/json { "event_type": "user.action", "entity_id": "user-123", "payload": {"action": "login", "source": "github"} } Response: 200 OK with event ID. ## How to query events Hosted HTTP reads pass through Query Service, which resolves tenant context and delegates durable event access to Core. Query Service also provides `/ws` Phoenix Channels, analytics routes, and per-tenant projection reads. GET https://api.all-source.xyz/api/v1/events/query?event_type=user.action&limit=10&order=desc Authorization: Bearer Response: {"events": [...], "count": 10} Results are ordered by (timestamp, version), ascending by default. Pass `order=desc` for newest first. ## Time-travel query (events before a timestamp) GET https://api.all-source.xyz/api/v1/events/query?entity_id=user-123&before=2026-04-22T00:00:00Z Authorization: Bearer ## Health check (no auth needed) GET https://api.all-source.xyz/health ## x402 priced route discovery (no auth needed) GET https://api.all-source.xyz/x402/routes ## Key endpoints POST /api/v1/onboard/start — Create tenant + API key (no auth) POST /api/v1/events — Ingest event POST /api/v1/events/batch — Ingest batch of events GET /api/v1/events/query — Query events (filters: event_type, entity_id, before, after, limit, order) GET /api/v1/projections — List projections GET /api/v1/schemas — List schemas POST /api/v1/schemas — Register event schema GET /api/v1/billing/catalog — Live pricing catalog (no auth) GET /health — Health check GET /x402/routes — x402 payment route discovery ## Authentication All API calls (except onboard, health, billing/catalog and x402/routes) require: Authorization: Bearer ## Storage and durability AllSource Core IS the database — a purpose-built Rust event store, not a cache in front of one. Events are written to a write-ahead log with CRC32 checksums and configurable fsync, persisted to Parquet with Snappy compression, and served from an in-memory concurrent map. Event data survives process restarts. There is no PostgreSQL in the event path. ## Licence Apache-2.0 for the repository, with BSL covering enterprise features (LICENSE and LICENSE-BSL at the repository root). Note that apps/core/LICENSE is still MIT — a deliberate carve-out — so both answers appear in our own tree. ## Tiers Five plans. There is no free hosted tier; self-hosting is the free option. Live prices come from GET /api/v1/billing/catalog and remain authoritative. The GBP figures below were verified against that endpoint on 2026-08-14. - Self-Host (free, your infra): unlimited events, forever retention, unlimited streams, full MCP, Apache-2.0. Not sold — you run it. - Indie (£18.99/mo; £181.99/year): 500K events/month, 14-day retention, 3 streams, hosted MCP read, 50K x402 calls - Studio (£78.99/mo; £757.99/year): 5M events/month, 90-day retention, unlimited streams, hosted MCP read + write, 500K x402 calls - Scale (£298.99/mo; £2,869.99/year): 50M events/month, 365-day retention, unlimited streams, hosted MCP read + write + dedicated, 5M x402 calls - Enterprise (custom): negotiated volume, unlimited retention, dedicated MCP cluster, SLA and compliance - New signups: 14-day trial (1,000 events), then pick a plan. # Tier names, quotas and retention per siteConfig.pricing in # apps/web/src/lib/config.ts. Charged prices come from LemonSqueezy via # /api/v1/billing/catalog. # Earlier hosted tier names and quotas are retired; use only the catalog above. ## SDKs (optional — plain HTTP works fine) - Rust: https://crates.io/crates/allsource - TypeScript: https://www.npmjs.com/package/@allsourcedev/client - Python: https://github.com/all-source-os/all-source (sdks/python-client) - Go: https://github.com/all-source-os/all-source (sdks/go) ## MCP Server The event-store MCP server exposes a tool count that depends on how it is configured: 55 default (remote, writes enabled) 45 with ALLSOURCE_READ_ONLY=true (hides the 10 mutation tools) 64 with ALLSOURCE_CONTROL_URL set (adds 9 tenant / fleet-health tools) 73 with ALLSOURCE_SYSTEM_ADMIN=true (adds 8 recovery tools + tenant_notice) Quote 55 for the default event-store connector and 73 for the full fleet-operator set. Stable event-store connector v0.22.0 does not send the Authorization header required by the hosted gateway. The fix is merged for v0.23.0 but is not released; use the authenticated REST API for hosted production until that image ships. Prime is a **separate** MCP server with its own 27 tools (19 graph/vector/recall `prime_*`, 2 `inbox_*`, 6 `hound_*`) — do not add the two together. See https://all-source.xyz/docs/mcp # Counts from the registry itself: list_tools/1 in # apps/mcp-server-elixir/lib/mcp_server_elixir/protocol/mcp_tools.ex (73 tool # entries, gated by read_only / control_plane_enabled / system_admin in # lib/mcp_server_elixir/server.ex), and tool_definitions() in # apps/prime-mcp/src/tools.rs (27 entries). ## Status page https://status.all-source.xyz ## More docs - Full API reference: https://all-source.xyz/docs/api - MCP integration: https://all-source.xyz/docs/mcp - Tenant setup guide: https://all-source.xyz/docs/tenant-setup - Connecting without an SDK: https://all-source.xyz/blog/connecting-without-an-sdk - GitHub: https://github.com/all-source-os/all-source
