Heartbeats

A heartbeat is a single-call run: started and finished in one request, no separate events. Lands in the same dashboard as full SDK runs; upgrading later doesn't migrate data.

For shell one-liners, see GET /v1/ping. This page covers the JSON POST variant.

POST /v1/heartbeats

https://eu.ingest.agentping.io/v1/heartbeats

Request

Field	Type	Required	Description
`id`	string	No	Client-generated. Format `run_<region>_<32 hex>`. Omit to let the server mint one.
`agent`	string	Yes	Slug. New agents are auto-created.
`status`	string	No	`ok`, `fail`, `start`, `timeout`. Default `ok`. `start` opens a run without finishing it.
`started_at`	string (ISO 8601, UTC)	No	Default: server receive time.
`finished_at`	string (ISO 8601, UTC)	No	Default: server receive time.
`cost_usd`	number	No	Total cost in US dollars. Overrides token pricing when both are sent.
`model`	string	No	Model id (e.g. `gpt-4o`). With token counts and no `cost_usd`, the run is priced from your rate card.
`provider`	string	No	Provider (`openai`, `anthropic`, ...). Pairs with `model` for pricing.
`input_tokens`	integer	No	Prompt/input tokens. Priced against the rate card when `model` is set.
`output_tokens`	integer	No	Completion/output tokens. Priced against the rate card when `model` is set.
`cached_input_tokens`	integer	No	Cache-read tokens, billed at the cached rate.
`duration_ms`	integer	No	If absent, computed from `started_at`/`finished_at` or from a prior `start` with the same `id`.
`metadata`	object	No	Flat key/value JSON. Paid feature, limits below.

Response

202 Accepted on first write. 200 OK on idempotent retry. 409 Conflict if id exists with mismatching agent or started_at.

Let AgentPing price it from tokens

When the caller has the model and token usage (an n8n AI node, a Make or Zapier step, a script that read the provider's usage block) send those instead of computing a cost:

curl -X POST https://eu.ingest.agentping.io/v1/heartbeats \
  -H "Authorization: Bearer ping_eu_018f3a2b9c1d7e8fa4b9c2d7e8f1a3b6" \
  -H "Content-Type: application/json" \
  -d '{
    "agent": "lead-enrichment",
    "status": "ok",
    "provider": "openai",
    "model": "gpt-4o",
    "input_tokens": 1240,
    "output_tokens": 380
  }'

AgentPing prices the run from your rate card. An unpriced model records at zero cost and shows in the unpriced-models banner on the Spend page.

Heartbeat vs full run

Aspect	Full run	Heartbeat
Number of HTTP calls	2 to N (start, events, finish)	1
Events recorded	One row per event	None
Cost computation	Server-side from `llm_call` events	Client `cost_usd`, or server-side from `model` + token counts
Per-step latency	Yes, per event	Run-level only
Best for	Agent loops with multiple LLM or tool steps	Webhooks, cron, n8n flows, single-action jobs

When to use heartbeats

Heartbeats fit when:

The job is a webhook (n8n, Zapier, Make, Vercel cron) and the SDK can't load.
The job is a shell script or Lambda with one LLM call wrapped in retries.
A team wants monitoring today; the SDK can be added later without losing history.

Full runs (POST /v1/runs + events + finish) fit when:

An agent makes more than one LLM call.
Tool calls or guardrail outcomes matter for debugging.
Per-step latency is interesting.
The SDK is already loaded.
