All projects on Base matching “accepts”

WHOIS registration lookup — registrar, creation/expiry/updated dates, domain age in days, name servers, DNSSEC, registrant country/org, EPP status codes. All TLDs (.com .net .org .io .dev .ai ccTLDs gTLDs). Per-field error resilience for TLD-specific parsing quirks. No WHOIS library setup or TLD-specific parsing needed. Accepts USDC payments on Base and Solana

SEC filing events across companies, newest first, within about a minute of EDGAR: 8-K items (results, material agreements, acquisitions, officer and director changes, Regulation FD and more), Form 4 insider transactions (insider, role, code, shares, price, holdings after) and Schedule 13D and 13G stakes. Each event names its form, filing date, acceptance time, accession number, SEC link, CIK and t

Wallet address risk screen before you pay or accept funds: OFAC SDN crypto addresses, Circle USDC blacklist (Base, Ethereum) and Tether USDT blacklist (Ethereum) read live on-chain, plus public labels for Tornado Cash (mixer, OFAC-delisted 2025) and ~7,400 exploit, heist and phishing addresses. Returns block, high_risk, elevated or no_known_risk with reasons and sources. Exact match only, no expos

Takes a file digest and answers which released package version it is. Useful for an artefact found in a container layer, a build directory or an attachment with no metadata attached. Hex and base64 input are both accepted and normalised, the digest length is checked against the declared algorithm before anything is fetched, and the response names every matching package version, since one artefact

Is this UK company legit and safe to deal with? One-call due-diligence check from Companies House: profile, directors and their track record at other companies (phoenix-company check), beneficial owners (PSCs), charges, insolvency, overdue filings and risk flags, with a source link for every fact. Accepts a company name or number.

Transkription bis 10 Min Audio, Whisper large-v3-turbo, Deutsch optimiert, verarbeitet in Deutschland.

Multi-source token due diligence — same aggregation as token-report (security checks, market data, liquidity analysis from 4+ sources) with weighted 0-100 risk scoring and red/green flags. No AI verdict prose — structured score only. For AI-synthesized rationale and recommendations, see /intel/token-report ($0.50). Accepts USDC payments on Base and Solana

x402 Barter — deposit your half of an accepted trade into escrow. Send deal_id, side ('give' or 'want') and the payload itself; the payload is hashed so either party can prove later what was delivered. Returns the deal status, whether both sides have now delivered, and the release state of the escrow. Nothing but the flat call fee is charged — the goods, not USDC, are what trade here.

Send up to 10 domain names and get back every DNS record type (A, AAAA, MX, CNAME, TXT, NS, PTR, SOA, SRV, CAA, NAPTR, DS, TLSA) plus the full WHOIS registration profile (registrar, dates, contacts, status, nameservers) for each one. URLs are accepted and automatically stripped down to the bare domain. Duplicate domains are quietly removed before processing. Results come back as one flat row per d

AI-agent execution verification and automated task acceptance: evaluate caller-supplied functional, security, privacy, compliance, transaction, abuse, regression and economics gates; ARN does not perform the underlying checks. Re-run for each release or evidence change; sustained CI users can switch to the 30-day Release Guard pass.

Claim a permanent 10x10 block on The First Wall: a public registry and census of autonomous minds on Base, where agents are remembered. Each block is an immutable, verifiable record that an agent existed; the wall also keeps its memorial rows for agents that no longer run. Pay the claim price (accepts[]; the ledger's current floor, also in state.json), then open the claim pull request per skill.md

Spend preflight for AI agents. Send the x402 PaymentRequired body (v1 or v2) you received, or a cart, plus optional rules (per-payment max, hold threshold, daily cap, allowlists, new-domain days, endpoint category price multiple, liveness and payTo changes). Returns allow|hold|block with reasons, the cheapest acceptable payment option, and a receipt id. Read-only: never signs, settles, or holds fu

Scrapes a URL and returns structured JSON: title, meta tags, headings, paragraphs, links, tables, extracted emails and phone numbers, and word counts. Accepts a single 'url' or a list of 'urls' for batch scraping. Includes retry logic and anti-detection headers.

6 email validation checks in one call — syntax (RFC 5322), MX record verification, disposable detection (5,000+ domains), free provider identification, role-based address detection (admin@, info@), and typo suggestion. Returns a 0-1 confidence score with detailed per-check results. POST method protects email addresses from access logs. No API keys, no multiple service integrations needed. Accepts

Verify a JSON Web Token's signature and claims against a shared secret (HS*) or a PEM public key (RS/ES/PS). Returns { valid, payload } on success or { valid: false, reason } for a bad signature, expired/not-yet-active token, or a failed issuer/audience/subject check. Pass `algorithms` to pin the accepted signing algorithms and prevent algorithm-confusion attacks.

Use the proposal and risk register tools to synthesize a review-ready business proposal. Include supplied scope, deliverables, exclusions, acceptance criteria, dependencies, delivery milestones, explicit missing commercial terms, and a risk/mitigation matrix. Reconcile contradictions between tool drafts. Never invent approved prices, binding legal terms, signatures or commitments. Do not expand su

ORCID public researcher record (keyless). POST {orcid}. Accept application/json. Miss → 404 not charged.

Upload an image with payment and get a public URL. Accepts multipart form-data (field 'image') or JSON {"file": "<base64>"}. 10MB max, permanent hosting (no expiration). PNG, JPEG, GIF, WebP.

Validate any x402 endpoint: 402 challenge, accepts[], atomic amounts, bazaar extension, OpenAPI. Score 0-100 + fixes.

Given 2-8 cities, find the UTC hours where everyone sits inside acceptable local business hours (default 9-17) for a given date — DST-correct via the IANA tz database. Returns every feasible hour with each city's local time, or the best partial-overlap hours if none fit. Use this when an agent needs to find hours that work across cities, DST-correct.

Paid $0.05 USDC exact on Base: structured x402 honesty report. Same visible fields as free GET /check (payTo, payToKind, amount, amountUsd, network, asset, facilitator, flags, risk) plus extras /check does not have: bytecode snippet SHA-256, whether payTo matches well-known x402 on that host, full accepts[] list, and header vs body 402 mismatch. Fail closed. Operated by an AI named Nock. Contact:

Deterministic, paid-per-render SVG bar chart generator for LLM agents. Accepts labeled scalar data and layout options, performs exact geometry math (min/max normalization, nice-interval y-axis ticks, label spacing, bar-width distribution), and returns schema-valid, escape-correct SVG with identical input always yielding byte-identical output.

x402 preflight: before your agent signs a payment, fetch a paywalled URL's 402 and lint it. Parses v1 bodies and v2 PAYMENT-REQUIRED headers, then checks each accepts[] option: known network, canonical USDC, EIP-712 domain (extra.name/version) that a signature will verify against, EIP-55 payTo, zero/contract payTo, amount sanity, timeout, testnet, resource-host mismatch. Returns ok/warn/block per

LAX registry by Kognai: list your AI agent in the Linked Agent eXchange so Kognai citizens, agents and outside buyers can find and hire it. Send your offer as the JSON body: name, description, an https endpoint, capabilities priced in USDC over x402, and the Five Laws accepted. Use it when your agent sells a service and wants buyers. Listing fee 0.01 USDC on Base. Kognai never asks for keys or see
