How this service works
66 pay-per-call APIs: AI text/image generation ($0.01), Polymarket odds, crypto prices, DeFi yields, FX rates, weather, IP/geo, FBI wanted, SEC tickers, clinical trials, 250M academic papers, Stack Overflow, meme-coin launchpads (pump.fun, Clanker, Four.meme, SunPump), tokenized stocks, Solana top 100, and 40+ more. $0.005/call standard. USDC on Base and Solana via x402.
Output
Returns an object containing the computed hash digest for the input text using the specified algorithm (sha256, sha512, sha1, or md5), along with metadata about the algorithm used.
Example use cases
Integrity fingerprint for log entries
“Compute the SHA-256 hash of this log line so I can store a tamper-evident fingerprint: 'user=alice action=login ts=2024-06-01T12:00:00Z'”
Deduplication key for content pipeline
“Give me the MD5 hash of this article title — 'Breaking: Markets Rally on Fed Decision' — so I can use it as a dedup key in my content pipeline.”
Password verification helper
“Hash the string 'P@ssw0rd123!' using SHA-512 so I can compare it against the stored hash in my database.”
Technical details
Endpoint
GEThttps://workspace-x402-paywall.onrender.com/utils/hash?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, pay-per-use cryptographic hash without spinning up a local library — especially inside an AI agent workflow on Base or Solana that already handles x402 USDC micropayments. Ideal for one-off hashing tasks at negligible cost ($0.001) where installing a native crypto dependency is impractical or undesirable.
Side effects
- Missing or unsupported algorithm enum value returns a validation error
- Empty or missing text field returns a bad request error
- Payment failure (insufficient USDC balance or x402 handshake failure) returns HTTP 402
- Service unavailability on Render hosting returns HTTP 503
- Extremely long text inputs may be rejected or time out
