How this service works
Low-cost x402 pay-per-call tools for autonomous buyers. Web extraction returns static public pages as clean markdown; every payable operation declares x-payment-info and a 402 response. Free betas: Agent Purchase Guard adds retry-safe purchase intent controls; Outcome Router accepts a desired result plus max budget and autonomously discovers fulfillment, tries zero-dollar proof-of-work first, and supports buyer-signed x402 paid execution where available. Buyer-signed paid HYDRA execution - Outcome request: POST https://earn-tools-backend.onrender.com/outcome-router - Paid execution: POST https://earn-tools-backend.onrender.com/outcome-router/execute/{requestId} - First execution call returns the relayed Agent402 Smart Order Router x402 PAYMENT-REQUIRED challenge. - An x402-capable buyer wallet signs locally and retries with PAYMENT-SIGNATURE. - HYDRA forwards the proof and returns the routed result. - HYDRA never receives the buyer private key or uses owner working capital. - Current beta platform fee: $0. Higher paid tiers are not auto-escalated.
Output
Returns a JSON object with ok: true and a result object containing the SHA-512 hex digest string under 'result', plus the operation name ('sha512') under 'operation'.
Example use cases
Integrity fingerprint for stored artifact
“Generate a SHA-512 hash of this JSON blob so I can store the fingerprint alongside it and verify it hasn't been tampered with later: '{"user":"alice","balance":1000}'”
Password hashing before storage
“Hash the passphrase 'correct-horse-battery-staple' using SHA-512 so I can store a secure digest instead of the raw value.”
Deduplication key for large text document
“Compute a SHA-512 digest of this article text so I can use it as a unique deduplication key in my content database: 'The quick brown fox jumps over the lazy dog, again and again...'”
Technical details
Endpoint
POSThttps://earn-tools-backend.onrender.com/sha512When to prefer
Choose this endpoint when you need a pay-per-call, agent-native SHA-512 hash computation without standing up your own crypto library or server. It is ideal for autonomous AI agents operating within an x402 micropayment loop that need to compute hashes on demand at $0.001 per call without managing infrastructure. Prefer alternatives (local libraries) when hashing at high volume or when latency is critical.
Side effects
- Input exceeds 500,000 character limit — request rejected
- Malformed JSON body — 400 bad request
- Payment not provided or invalid x402 signature — 402 Payment Required returned
- Service temporarily unavailable on Render cold start — 503 or timeout
- Empty input string may return a valid hash of the empty string (edge case to handle downstream)
