Text Checksum & Hash API

x402

Text Checksum & Hash API is a paid API for AI agents from agent-chain-kit-solana.vercel.app, paid per call via x402, $0.0005/call, status unknown (last checked 2026-10-09).

Computes deterministic hash digests (MD5, CRC32, SHA-256) and byte count for a given text string

How this service works

Global current weather, hourly forecasts, foreign-exchange rates, EVM reads, and deterministic utilities for AI agents. Pay per call with MPP or x402; no API key.

Output

Returns a JSON object containing the MD5 hex digest, SHA-256 hex digest, CRC32 checksum, and byte count of the input text string

Example use cases

Integrity check before file upload

“Before I upload this config file, can you hash the text contents and give me the MD5 and SHA-256 so I can verify nothing changed after transfer? The text is: 'server_host=localhost port=8080 debug=false'”

Fingerprint API response for caching

“I need a deterministic fingerprint for this JSON payload to use as a cache key — can you give me the SHA-256 and CRC32 of the string '{"user":"alice","role":"admin"}'?”

Verify downloaded content matches expected hash

“I downloaded a file and the vendor says the MD5 should be 5d41402abc4b2a76b9719d911017c592 — can you hash the text 'hello' and check if the MD5 matches that value?”

Endpoint

When to prefer

Choose this endpoint when you need multiple hash formats (MD5, SHA-256, CRC32) returned in a single call without managing API keys, paying per-call via micropayment protocol (x402/MPP). Useful for lightweight integrity checks in agent workflows where a traditional SDK or heavy library is impractical.

Side effects

Missing required 'text' query parameter returns validation error
Unsupported HTTP method (POST/PUT) rejected with 422
Empty string input may return zero-byte result
Payment failure (x402) blocks request if USDC balance is insufficient
