# Messari Network Metrics Discovery

> Messari Network Metrics Discovery is a free API for AI agents from api.messari.io, Free, status unknown (last checked 2026-09-13).

Returns available blockchain network metric dataset slugs and their supported time granularities for use in subsequent data queries.

## Facts

- Endpoint: POST https://api.messari.io/metrics/v2/networks/metrics
- Price: Free
- Status: unknown
- Last checked: 2026-09-13
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/messari-network-metrics-discovery-993c2c2f
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_K4tsTbCqH7wz_dvUXMFOL

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability messari-network-metrics-discovery-993c2c2f -d '<json body>'
```

Example prompt: What blockchain network metric slugs does Messari support, and which granularities like 1h or 1d are available for each one?

## When to prefer this

Use this endpoint before querying network metric history to discover valid slugs and granularities. Prefer this over the asset metrics discovery endpoint when you are working with blockchain network-level data (e.g. node counts, transaction throughput) rather than asset price or market data. Essential for parameterizing subsequent time-series requests correctly.

## Known failure modes

- Invalid request body returns 400 with validation error
- Authentication failure returns 401 if API key is missing or invalid
- No matching metrics found returns empty data array
- Rate limit exceeded returns 429
- Network timeout or service unavailability returns 503

## How this service works

Find blockchain network metric dataset slugs and supported granularities.

## Output

A structured list of metric categories (e.g. Activity), each containing named metrics with their slugs (e.g. tx_count) and the time granularities they support (e.g. 1d, 1h) — used to build valid queries against Messari network metric history endpoints.
