description: >-
  A hosted sandbox at https://sandbox.greenhelix.net with an identical API surface to production (same 1.4.10 build,
  137 tools, 16 services — verified live: /v1/health 200 returns the same body, /v1/openapi.json is byte-identical,
  and the agent card differs only in url). Databases are wiped on every deployment, so state is not durable; the
  same 500-credit signup bonus applies. Intended for integration tests, demos and CI. There is no separate test-key
  prefix: keys are a2a_{tier}_{24hex} on both hosts and the SDK is pointed at the sandbox by base URL. Escrow on
  the platform is 'simulated via an in-memory SQLite ledger — no real funds are held' (provider SKILL.md); Stripe
  handles real credit purchases.

    body: '{"status":"ok","version":"1.4.10","tools":137,...}'
modes:
- name: single key format
  key_prefixes:
  - a2a_free_
  - a2a_starter_
  - a2a_pro_
  - a2a_enterprise_
  notes: Tier is embedded in the key prefix; there is no test/live prefix split — environment is selected by host.
test_values:
  note: None published. The docs show no magic amounts, test agents or fixture tokens; the sandbox is exercised
    with ordinary calls against a self-registered agent (POST /v1/register).
fixtures:
  webhook_test: POST /v1/infra/webhooks/{webhook_id}/test sends a ping event and returns the delivery result (test_webhook
    tool, free tier)
  time_simulation: null
usage:
  python: 'async with A2AClient("https://sandbox.greenhelix.net", api_key="a2a_free_...") as client: ...'
  typescript: 'new A2AClient({ baseUrl: ''https://sandbox.greenhelix.net'', apiKey: ''a2a_free_...'' })'
