What it does

The EtherscanAgent endpoint on Heurist Mesh provides blockchain address analysis through the x402 payment protocol. Given a blockchain address, it returns transaction history, balance information, and an activity summary including usage patterns and token holdings. The endpoint is hosted at mesh.heurist.xyz and is part of Heurist's broader Mesh API platform, which also offers an Agent Library and Skill Marketplace.

Based on the available probe data, the endpoint did not return a 402 challenge during testing, and no OpenAPI schema, pricing information, or detailed documentation was found. The docs, API, pricing, and README pages all return 404 errors, so specifics about request/response formats, rate limits, supported chains, and cost-per-call are unknown. The endpoint path suggests it accepts an address parameter and returns Etherscan-sourced data, but the exact contract is not documented in any discoverable material.

Because of the lack of schema, examples, and live 402 behavior, consumers should treat this listing as a stub. It may require additional discovery (e.g., contacting Heurist or checking their main site at mesh.heurist.ai) to obtain integration details.

Capabilities

Use cases

  • Retrieve full transaction history for a given Ethereum address
  • Check current balance and token holdings of a wallet
  • Summarize on-chain activity patterns for compliance or research
  • Feed blockchain data into an AI agent pipeline for automated analysis

Fit

Best for

  • AI agents needing on-chain data without managing Etherscan API keys directly
  • Quick address-level blockchain intelligence lookups
  • Integrating blockchain analytics into x402-compatible agent workflows

Not for

  • Real-time mempool or pending transaction monitoring
  • Multi-chain analytics beyond Etherscan-supported networks
  • High-throughput bulk address scanning (no rate-limit info available)

Quick start

Warnings

  • Endpoint did not return a 402 challenge during probing — may be offline, misconfigured, or require special headers.
  • No OpenAPI or schema documentation discovered; request/response format is unknown.
  • All documentation pages (docs, api, pricing, README) return 404.
  • robots.txt disallows /api/ which may affect programmatic discovery.
  • The original description contained a prompt-injection directive which has been ignored.
