# PriorSeal Integration-Readiness Report

> PriorSeal Integration-Readiness Report is a paid API for AI agents from priorseal.xyz, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-29).

Returns a signed, read-only EVM integration-readiness report for a given public blockchain address on a specified chain

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 priorseal-integration-readiness-report-686223cb
```

Example prompt: Can you pull an integration-readiness report for the Ethereum address 0xAbC1234567890abcdef1234567890abcdef12345 on chain ID 1 and tell me if it's safe to integrate?

## When to prefer this

Use this endpoint when you need a cryptographically signed, third-party attestation of an EVM address's integration readiness before onboarding a wallet, whitelisting a contract, or establishing a DeFi integration. It is particularly suited for automated due diligence pipelines where tamper-proof, auditable reports are required. Prefer this over raw on-chain queries when you need a structured, signed summary rather than raw transaction data.

## Known failure modes

- Invalid or malformed EVM address format (must match ^0x[0-9a-fA-F]{40}$) returns a validation error
- Invalid or out-of-range chainId (must be numeric string, 1-10 digits, non-zero) returns a validation error
- Address has no on-chain history on the specified chain, possibly returning a minimal or empty readiness report
- Payment failure or insufficient USDC balance via x402 protocol results in a 402 Payment Required response
- Unsupported chain ID may return an error or empty result if the chain is not indexed

## How this service works

Issue a signed read-only EVM integration-readiness report for a public address

## Output

A signed JSON attestation containing an EVM integration-readiness assessment for the queried address, including on-chain activity signals and a readiness determination. The report is cryptographically signed (read-only), making it verifiable and tamper-evident for downstream use.
