Open source API for developers who need agents to monitor links, track deliveries, and report findings — without building schedulers, webhook plumbing, or LLM tool loops. Results POST to your endpoint.
Self-host anywhere · Run on the stack you already ship
01 · The primitive
Every product that watches the world rebuilds the same stack: schedulers, LLM tool loops, page diffing, webhook retries. Meerkat collapses that into a single open source resource.
02 · Lifecycle
POST /api/v1/tasks
description: "watch URL"
input_params: {...}
output_webhook: "/hook"
providers:
anthropic | openai
openrouter | grok
key: encrypted at rest
agent.execute()
→ on schedule
→ on demand
→ change detection
POST your-app.com/hook

06 · Architecture
A task moves through three actors. You register it, Meerkat schedules and orchestrates, an LLM (your key) executes, and a signed webhook lands back at your endpoint.
03 · Self-host
Self-host Meerkat with the same REST API as Cloud. You run Postgres and workers; users connect their own LLM keys. MIT licensed, no vendor lock-in.
04 · Run it your way
Same open source codebase. Same API. Pick the operating model that fits your team.
05 · BYOK
Meerkat never resells AI tokens. Each account connects an encrypted API key. Model costs go to your provider; Meerkat charges only for scheduling, execution, and webhooks.

07 · In production
Drop in DHL, FedEx, or UPS URLs. Meerkat polls, diffs, and webhooks only when the state actually moves.
Price drops, restocks, availability shifts — converted into compact JSON your app can react to in one route.
Per-run snapshots are diffed against history. You get a summary of what changed, not an HTML payload to parse.
Fire a single task for research, scraping, or extraction. Marked complete after the webhook lands.
08 · API surface
JSON in, JSON out. Bearer auth. Idempotent retries. Signed webhooks. The whole surface fits on one screen — identical between self-host and Cloud.
