AgentResolver SHA-256 Hash Endpoint
x402
AgentResolver SHA-256 Hash Endpoint is a paid API for AI agents from agentresolver.vercel.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-18).
Computes the SHA-256 cryptographic hash of an input string and returns the hex-encoded digest along with metadata about the operation

How this service works
Verify an x402 endpoint before paying: live payTo, USDC quote, network, asset, resource binding, TLS and endpoint safety for $0.001 on Base or Solana.
Output
Returns a JSON object containing the operation name ('sha256'), the number of bytes in the input, the encoding of the result ('hex'), and the resulting SHA-256 hash as a hexadecimal string digest.
Example use cases
Verify file content integrity
“Hash this string for me using SHA-256 so I can confirm the file contents haven't been tampered with: 'user_data_export_2024_v2'”
Generate deterministic content ID
“I need a unique deterministic identifier for this document snippet — can you SHA-256 hash this text: 'This is the canonical version of our terms of service, updated June 2024'?”
Create hashed token for deduplication
“Take this event payload string and give me its SHA-256 hash so I can use it as a deduplication key: 'order_id=98234&user_id=5512×tamp=1717200000'”
Technical details
Endpoint
POSThttps://agentresolver.vercel.app/api/sha256When to prefer
Choose this endpoint when you need a fast, deterministic SHA-256 hash of a string and don't want to run local crypto code. Ideal for agents that need to fingerprint, deduplicate, or verify content integrity without access to a native hashing library. At $0.001 USDC per call it's cost-effective for low-to-medium volume use cases.
Side effects
- Missing 'input' field in request body returns a validation error
- Empty string input may be accepted but produces the known SHA-256 hash of empty input
- Very large input strings may cause timeouts or payload size rejections
- Malformed JSON body returns a parse error
- Non-string input types in the 'input' field may cause type validation failures
