# how.is Bot Observatory – Partner Tier

> how.is Bot Observatory – Partner Tier is a paid API for AI agents from how.is, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-30).

Returns the full partner-tier dataset of bot network traffic seen in the last 7 days: every ASN, named crawler, TLS/JA4 fingerprint, and firewall rule, refreshed hourly.

## Facts

- Endpoint: POST https://how.is/v1/bots?utm_source=zero.xyz
- Price: $0.05/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-30
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/how-is-bot-observatory-partner-tier-83bd74b9
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_STKioLAzjxC2ocyDKr5wE

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 how-is-bot-observatory-partner-tier-83bd74b9 -d '<json body>'
```

Example prompt: Pull the full partner-tier bot observatory snapshot from how.is — I want to see every ASN, named crawler, JA4 TLS fingerprint, and firewall rule recorded in the last 7 days.

## When to prefer this

Choose this endpoint when you need comprehensive, up-to-date bot network intelligence beyond what the free public tier offers — specifically when you require ASN-level data, JA4 TLS fingerprints, and firewall rule telemetry together in a single hourly-refreshed snapshot. Prefer this over the free dns.pizza/bots endpoint when you need partner-tier completeness for security auditing, CDN tuning, or automated threat intelligence pipelines.

## Known failure modes

- Payment not received or insufficient USDC balance — 402 Payment Required response
- Malformed request body not conforming to required schema — 400 Bad Request
- Service temporarily unavailable during hourly refresh cycle — 503 or timeout
- Rate limiting if the endpoint is called excessively — 429 Too Many Requests

## How this service works

Partner tier of the dns.pizza bot observatory: every network (ASN), named crawler, TLS (JA4) fingerprint and firewall rule seen in the last 7 days, refreshed hourly. The public tier is free at https://dns.pizza/bots.

## Output

A structured dataset containing all bot-related network observations from the past 7 days: ASNs (autonomous system numbers), named crawler identities, TLS JA4 fingerprints, and triggered firewall rules — sourced from the dns.pizza bot observatory partner tier and refreshed hourly.
