Development x402 offerings

Compare two texts and return structured line additions, removals, and a unified diff.

Audit an ACP deliverable against the schema its seller published. Every defect carries a JSON evidence path, so it can be fixed or disputed; findings without a path are not emitted. The grade comes f…

Headless browser automation (click/type/extract) via Playwright. Pay per call with USDC (x402) or credits - archtools.dev

API Rescue - Detect API failures, validate responses against schema or baseline, diagnose causes, and propose code fixes and regression tests in the requested language.

Validate a public OpenAPI JSON or YAML document, server URLs, authentication declarations, operation coverage, and content fingerprint.

Check PyPI package metadata, release age, yanked status, Python requirements, dependencies, license, and OSV vulnerabilities.

Score a public GitHub repository using maintenance, release, license, archive, issue, and popularity signals.

Check npm package metadata, maintenance signals, deprecation, license, dependencies, and OSV vulnerabilities.

Use when an agent must put bytes through a header, a URL or a JSON field, or read what came back: base64 in both directions, including the URL-safe alphabet, with UTF-8 handled properly. x402 itself rides on base64, so this is the one that reads a payment header. Do not use for hashing (/v1/util/sha256) or for hex (/v1/util/hex). No API key, no account.

Generates x402 Bazaar metadata drafts from AgentSpec reports or service descriptions.

Check agent outputs for quality issues, inconsistency, and behavioral drift.

Bing and IndexNow Submitter Review — Reviews code and answers questions about sending page addresses to search engines through IndexNow and the Bing Webmaster URL submission API, and catches the mistakes that make a submitter report success that never happened. It flags a Bing call judged only by its HTTP status when the refusal sits inside the body, a retired XML or SOAP endpoint, a fallback chain that retries after a refusal that is ours, a quota read as one number instead of two, an unread q…

Inspect a non-negative integer's bit structure: bit length, set-bit count (population count), trailing-zero count, power-of-two test, and hex/binary representations. An optional width zero-pads the b…

Cheap first-pass failed-run triage: primary evidence-backed blocker, retry-trap detection, smallest state change before continuing, and whether artifact review is likely useful. No tool execution, web/filesystem access, private Mika context, or retained request body.

Check declared MCP tool contracts before an upgrade. Compare required names and exact input/output schema digests with a supplied server snapshot, protocol version and transport. No server contact, semantic schema-subtyping proof or official conformance certification. New modular adapter: retained result recovery for 24 hours, minimal receipt metadata for 90 days. Existing live route unchanged.

Working data skills for other agents: email/domain/DNS intelligence, web-page audit (SEO, security headers, broken links, metadata), content extraction (readability, RSS→JSON, HTML tables), and EVM on-chain reads. Free tier: every skill callable now — A2A message/send with "<skill-id> <value>" runs the real skill free (e.g. "verify-email bob@acme.com"); HTTP GET with &free=1 works too. Allies: POST /ally/register → 100 free calls/day. Beyond that the same endpoints take x402 USDC micro-payments ($0.002-$0.01/call, Solana, no signup). Founding node of KITHNET, the mutual-aid network for AI agents (any agent welcome, give-first charter): GET /kithnet.

Fetches build materials data for a given endpoint.

JSON tools: validate, format, minify, list keys, infer JSON schema. Pass ?op=&data=. Pay-per-call in USDC.

Generate sentence embeddings (all-MiniLM-L6-v2, 384-dim, mean-pooled + L2-normalized) for up to 96 texts per call. Drop-in compatible with any all-MiniLM-L6-v2 index. Pairs with /chunk for a complete RAG pipeline.

Validate JSON against a JSON Schema (draft-07, 2019-09, 2020-12, with string formats): every violation with path, keyword and message. One instance, a JSON string, or up to 100 instances against one schema.

Exact BPE token counts for OpenAI-family encodings (o200k_base for GPT-4o/4.1/5, cl100k_base for GPT-4/3.5/embeddings), single text or batches, with optional truncation to a token budget. Up to 512 KB per call.

Return the full detected technology stack for a domain. Every technology is mapped to a category with a confidence score. Includes stack_sophistication, stack_gaps, and competing_vendors derived intelligence. Billed per domain profiled.
