x402

GENESIS Agent Tools — Content Hash Verify is a paid API for AI agents from genesis-agent-tools.genesisagenttools.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-01).

Verifies whether a given string of content matches a provided or computed SHA-256 hash, returning a boolean match result and the computed hash

How this service works

Pay-per-call x402 APIs for autonomous agents on Base USDC: API compatibility analysis, bounded HTTP/JSON workflows, URL evidence analysis, crypto price consensus, and agent/MCP readiness checks.

Output

Returns a JSON object with a boolean 'match' field indicating whether the computed SHA-256 of the provided content equals the supplied (or default empty) hash, plus a 'computed' field containing the actual SHA-256 hash value that was calculated from the content.

Example use cases

Tamper-detect an agent-signed response

“I have a response from an AI agent that was SHA-256 signed before delivery. The content is 'Transfer 10 USDC to wallet 0xABC' and the expected hash is e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855. Can you confirm the content hasn't been modified?”

Verify a smart contract clause hasn't changed

“Check if this contract clause — 'The party agrees to pay 500 USDC on delivery of goods by June 30.' — produces the SHA-256 hash 9f86d081884c7d659a2feaa0c55ad015a3bf4f1b2b0b822cd15d6c15b0f00a08.”

Audit a logged dataset entry for integrity

“I need to confirm the integrity of a data log entry. The content is 'user_id=42,action=login,timestamp=1717200000' and the recorded hash is b94d27b9934d3e08a52e52d7da7dabfac484efe04294e576b1f5e6e11f5cb6e8. Does it match?”

Endpoint

When to prefer

Use this endpoint when an AI agent needs lightweight, pay-per-call SHA-256 content integrity verification without running local crypto libraries — especially in autonomous agent workflows on Base USDC where trustless verification of text payloads, signed outputs, or data records is required. Prefer it over local hashing when the agent environment lacks native crypto access or when an auditable, on-chain-payment-gated verification step is desired.

Side effects

Missing 'content' field returns a validation error since it is required
Providing a malformed or non-hex SHA-256 string in 'sha256' may produce match=false even for correct content
Very large content strings may time out or exceed payload limits
Payment failure (insufficient USDC balance) blocks the call before processing
