Forest Agent Tools – SHA-256 / SHA-512 Text Hasher
x402
Forest Agent Tools – SHA-256 / SHA-512 Text Hasher is a paid API for AI agents from http--forest-gas-station-mainnet--lcjl27p8lmjs.code.run, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-20).
Deterministically hash up to 100 KiB of UTF-8 text with SHA-256 or SHA-512, returning both hexadecimal and Base64 digests with no external network calls.

How this service works
Machine-readable contract for active Forest paid capabilities. Unsigned paid calls return HTTP 402 with a PAYMENT-REQUIRED x402 challenge.
Output
Returns a JSON object containing the hex-encoded digest, the Base64-encoded digest, and the algorithm name used, computed locally without any external network calls.
Example use cases
Content fingerprinting for dedup pipeline
“Hash this article body with SHA-256 so I can store the fingerprint and detect duplicates later: 'The quick brown fox jumps over the lazy dog — an old pangram used in typography.'”
Config value checksum for drift detection
“Compute the SHA-512 hash of this config string so I can compare it against the stored checksum to see if anything changed: 'db_host=prod.db.internal;port=5432;pool=10'”
Deterministic ID generation from user input
“I need a stable, reproducible identifier from the email address 'alice@example.com' — can you SHA-256 hash it and give me both the hex and Base64 versions?”
Technical details
Endpoint
POSThttps://http--forest-gas-station-mainnet--lcjl27p8lmjs.code.run/text/hash?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a deterministic, side-effect-free hash of text data (up to 100 KiB) without trusting a third-party cryptographic service or running local code. Ideal for agents that need reproducible content fingerprints, checksums, or stable IDs from text values in a sandboxed environment. Prefer SHA-512 when collision resistance is paramount; SHA-256 for compact digests. Not suitable for password hashing (no salt/stretching) or HMAC operations.
Side effects
- Text exceeds 100 KiB limit — request rejected with a 4xx error
- Invalid algorithm value (not 'sha256' or 'sha512') — validation error returned
- Missing required 'text' or 'algorithm' fields — schema validation error
- Payment not attached or insufficient USDC — 402 Payment Required
- Non-UTF-8 byte sequences in input — encoding error
