x402

x402 Paid MCP — SHA-256 Hash is a paid API for AI agents from x402-paid-mcp.vercel.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-10).

Computes the SHA-256 cryptographic hash of any input string, with support for utf8, hex, and base64 encodings, paid per-call via USDC on Base or Solana using the x402 protocol.

How this service works

Compute a SHA-256 hex digest of a text payload. Cryptographic hash / checksum helper. Not an attestation.

Output

Returns the SHA-256 hash digest of the provided input data, computed server-side. The response reflects the hashed output of the input string interpreted under the specified encoding (utf8, hex, or base64). Each call costs $0.001 USDC, debited via x402 micropayment on Base or Solana.

Example use cases

Verify file integrity before processing

“Take this base64-encoded file payload and compute its SHA-256 hash so I can confirm it hasn't been tampered with before I store it.”

Deduplicate content by hash

“Hash this UTF-8 string 'invoice-2024-07-15-client42' with SHA-256 so I can use the digest as a unique key to detect duplicate records.”

Hash hex-encoded binary data

“Compute the SHA-256 digest of this hex-encoded binary blob: 'deadbeef0102030405' — give me the hash output.”

When to prefer

Choose this endpoint when you need a paid, on-demand SHA-256 hash computation accessible via the x402 micropayment protocol, especially within agentic workflows that already use x402/USDC payments on Base or Solana. It is ideal when you want a trustless, metered cryptographic primitive without managing your own hashing infrastructure. Prefer alternatives (local computation or free APIs) when cost per call is a concern and you can hash locally.

Side effects

Missing 'data' field — returns 400 Bad Request
Invalid encoding value (not utf8/hex/base64) — schema validation error
Malformed hex or base64 input when encoding is set accordingly — parsing error
Payment failure or insufficient USDC balance — returns 402 Payment Required
Network or Vercel cold-start timeout — transient 5xx error
