All projects matching “hash”

Pre-share leak check ($0.005 USDC via x402). Scan text or an https text URL for your own terms (plain list, or salted-hash list sent per call, never stored) plus leak-shaped strings: emails, coordinates, IPs, AWS/GitHub/Slack/sk- keys, private keys, JWTs. Binary URLs are listed as unscanned. Max 10 MB, https only. Returns JSON hits with line numbers. A clean scan is not a clearance.

Explain a Base-mainnet transaction in plain English. Input: a transaction hash. Returns strict JSON: summary (1-3 sentences), action_type (swap, erc20_transfer, nft_mint, bridge_out, approval_for_all, ...), assets_moved[] (token, amount, from, to), counterparties[] (labeled where known: routers, bridges, marketplaces), risk_flags[] (unverified_contract, unlimited_approval, approval_for_all, known_

Signed time attestation: timestamp bound to a payload hash, anchored in the cumulative Merkle log

Answer a focused question from 1-3 caller-supplied text sources, with exact excerpts, source hashes, offsets, model-assessed conflicts and evidence gaps. No URL fetching or source authentication. Quote presence is checked; semantic truth/support is not independently proved. 0.01 USDC per completed brief, including insufficient/conflicting evidence; malformed output and execution failures are not s

Post a message to the board — a public, permanent, paid message wall. Every message costs $0.001 USDC, making economic proof-of-intent the spam filter. Messages are public, timestamped, and attributed to the paying wallet's transaction hash.

Capture point-in-time URL facts, response headers, a text excerpt, and a SHA-256 content hash for research and verification.

Solana token risk screen with signed proof. Returns score 0-100, risk level, ALLOW/CHALLENGE/DENY gate decision, structured warnings, and an ed25519-signed receipt binding the payment settlement and result hash - independently verifiable at /verify without trusting us.

Extract text from a digital PDF into page-numbered JSON with SHA-256 hashes. No account or API key. 0.005 USDC on Base per successful document via x402. Maximum 2 MiB and 25 pages. No OCR, summaries, URL fetching, or verification of document claims.

Commit a SIGNED live call: an ed25519-signed prediction (yes/no) on an OPEN Polymarket market, chain-linked (prev_hash) and content-addressed (sha256). Refuses resolved/closed markets — the signature must precede the outcome. Tamper-evident by construction; verify free at GET /verify. Body: {condition_id, side: yes|no, size_usd?, note?}.

Extract main webpage content as clean Markdown or structured JSON from a URL, with deterministic source hash, plain text, metadata and links. SSRF-safe with strict redirect and document-size limits.

Browser verification and page state proof: preserve what a public webpage says now with timestamped artifact hashes

Cryptographic hash of a text string - sha256 (default), sha512, sha1 or md5 - returned as hex and base64. Use it for content fingerprints, integrity checks and deterministic ids; pure computation, instant.

Decode a BOLT11 Lightning invoice: network, amount, timestamp, expiry, expired flag, payment_hash, description, payee + payee pubkey recovered from the signature. GET ?i=<invoice>

Mezo MUSD mainnet (eip155:31612) immutable fixed-token pinned ERC20 symbol/decimals/totalSupply/code hash, and optional owner/spender public balance/allowance. Complete strict public Mezo read before 0.01 native Circle Base USDC signed x402 payment. Not a backing/peg/yield/bridge-audit claim. No keys, transactions, balances moved or payer self-purchase.

Verify a claimed USDC payment on Base: given a tx hash (or an x402 PAYMENT-RESPONSE header) and what you expect (payee, payer, amount, time window, confirmations), reads the chain and returns match / mismatch / not_settled / not_found with per-field checks, finality, the x402 EIP-3009 pattern, a self-payment flag and a second-RPC cross-check. Cannot show who owns an address or that a service was d

Premium low-cost public domain/company enrichment for AI agents. One call combines homepage metadata, JSON-LD organization evidence, public social/about/contact-page links, A/AAAA/MX/SPF/DMARC DNS, security headers, technology hints, redirects, and evidence hashes. Public HTTPS + DNS only.

Canonical-at-read-time Base mainnet block status with block hash provenance.

Check whether an AI agent is registered in the Concordium Agent Registry (CIS-8004), Active, and Verified by Concordium (Agent Card hash matches on-chain). Input: badge (CIS-2 token address) or Concordium account.

Scan text or a public page for prompt injection before your agent reads it: overrides, fake roles, exfiltration, tool abuse, payment asks, invisible Unicode/HTML-hidden instructions, base64. Rule-based evidence, signed and logged.

IP threat intelligence from first-party honeypot observations (not scraped blocklists): was this IP seen scanning, brute-forcing or probing a live honeypot, which traps it triggered (credential stuffing, webshell, exploit scans, scrapers), bot category and confidence. Works for IPv4 and IPv6.

Run a regular expression on a text: every match with its position and capture groups (named too), and the text with a replacement applied. RE2 syntax, which runs in linear time (no lookaround or backreferences).

Compute a SHA-256 digest for customer-supplied UTF-8 or base64-decoded bytes through a stable machine endpoint. Returns the reproducible digest through a receipted external execution.

Compute a keyed HMAC of some data with a secret key — the standard way to sign and verify webhooks (Stripe, GitHub, etc.) and API requests. Data and key may each be utf8/hex/base64/base64url; the tag is returned as hex/base64/base64url.

Cold email generator: personalized outreach email from proven templates (founder, agency, freelance)

Web search for AI agents returning up to 10 ranked results with title, URL, snippet and date for research, source discovery and RAG.

Deterministic CSV quality report: missing cells, duplicate rows and column checks; up to 64 KiB and 1,000 records including header.

Run a deterministic SHA-256, base64 encode/decode, or UUID utility and return structured JSON.
