# Blockscout Stability Validators List

> Blockscout Stability Validators List is a paid API for AI agents from api.blockscout.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-11).

Returns a paginated list of stability validators for a specified blockchain network, including their state, address details, and block validation counts

## Facts

- Endpoint: GET https://api.blockscout.com/%7Bchain_id%7D/api/v2/validators/stability
- Price: $0.002/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-11
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/blockscout-stability-validators-list-9fb9d9c9
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_W5ZB4kjL5NQ5QwP8D7VgQ

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 blockscout-stability-validators-list-9fb9d9c9
```

Example prompt: Pull the list of active stability validators on chain 1 from Blockscout, sorted by blocks validated in descending order, so I can see who's been most active.

## When to prefer this

Use this endpoint when you need structured, paginated validator data for a specific EVM-compatible blockchain supported by Blockscout, especially when you need rich address metadata (ENS, tags, reputation, proxy type) alongside validation statistics. Prefer this over raw RPC calls when you want curated, enriched validator data without parsing raw chain state yourself.

## Known failure modes

- Invalid or unsupported chain_id returns a 404 or empty result
- Unknown address_hash returns an empty items array
- Invalid state_filter value may return a 400 error or empty results
- Pagination exhausted — next_page_params is null when no more results exist
- Network timeout or upstream blockchain node unavailability causes 503
- Payment failure (x402) if USDC balance is insufficient blocks the request

## Output

A paginated JSON object containing an array of validator items, each with the validator's state (e.g. active, jailed), full address details (hash, name, ENS domain, proxy type, reputation, scam flag, public/private tags, implementations, watchlist names), and the total count of blocks they have validated. Also includes next_page_params for cursor-based pagination.
