Cross-border VAT treatment for a digital-services sale: place of supply, who accounts, rate basis, registration trigger — the applied rule cited to the statute (EU, UK & South Africa; defined supply pairs)

Measure achieved reliability against an SLO target from good and total events. Use it before an autonomous workflow acts on untrusted input, changes an API, retries a request, or evaluates production reliability. Returns bounded machine-readable JSON for $0.002 USDC via x402 on Base. Execution is deterministic, first-party, local-only, stateless, and does not call an upstream provider; structured validation failures are not billed.

Medieval-fantasy names: Original names for towns, kingdoms, characters, taverns and legendary items. Duplicates are removed. Useful for games, stories and world-building.

Render one public page in headless Chromium after robots and public-address checks, wait for scripts to settle, then return bounded visible text, title, final URL and source links. Standard x402: POST the URL, sign the 402 and resend the same body. The 402 also returns an encrypted payment_request that pays for exactly the quoted render. Failed renders are never charged. No login, interaction, screenshots or full-site crawl.

Check one email address or domain. Report common address syntax, MX or null MX and A/AAAA fallback, SPF, exact-domain DMARC and optional caller-supplied DKIM selector records, and a small known disposable-domain list. DNS failures remain unknown. Does not verify a mailbox or predict delivery.

Validate CSV before import using a fixed JSON column specification. Checks missing/extra columns, required cells, string/integer/decimal/boolean/date types, uniqueness, allowed values and numeric/row-count bounds. Returns pass/fail with row/column error codes. POST JSON with csv and spec.columns; schemas/examples attached. Full contract: /openapi.json. Max 2,000 rows, 50 columns, 256 KiB; first 50 failures. No formulas, cross-column rules, fact checking or data repair.

Base or Solana, 0.05 USDC per completed scan. Failed or expired unfinished work is uncharged; never replace a pending proof. Reports expire after 24 hours. Probes never pay targets or certify paid delivery.

Check source overlap before counting corroboration. Supply 2-10 URLs, optional article HTML and citation chains. Returns duplicate URLs, shared links and supplied-source groups with locations. No fetching, truth or independence verdict. Schemas: /openapi.json.

Fetch one public static HTML page after robots and public-address checks, then return bounded readable text, title, final URL and source links. This is a two-step x402 purchase: the initial URL-only call returns an encrypted payment_request; send that unchanged with a signed proof. No browser, login, summary or full-site crawl.

Validate a fixed JSON CSV column specification before assigning extraction or checking deliveries. Send typed column settings in requirements; returns the validated spec for /v1/data/csv/validate-data. Rejects unknown fields and unsupported settings. This checks the specification itself, not CSV data. No custom expressions, cross-column rules or prose-to-rule conversion. Schemas/examples attached; full contract: /openapi.json.

Prepare six annual US-GAAP USD fields by CIK with SEC sources, same-filing growth checks and optional observed revisions. Free SEC data; paid selection and checks. Inspect coverage before paying. Mechanical checks do not establish accounting comparability or explain restatements.

Generate text or JSON completions for one to 20 independent tasks. Choose GPT-6 Luna or GPT-6.1 Sol, or let task-based rules select each model. Review the selected models and total price before payment. Receive a private asynchronous job and recover stored results after completion. No tools, browsing or streaming.

Find recent topic news or poll for new-to-agent links using a bounded follow-up checkpoint and seen history. Return normalized links, exact-link/headline deduplication and optional source-linked headline highlights from a7-day GDELT headline index. Monitoring dates are not verified publication dates.0.01 USDC per completed search, including no new links; source failures are uncharged.

Validate CSV before import using a fixed JSON column specification.

POST JSON with csv and spec.columns; schemas/examples attached. Full contract: /openapi.json. Max 2,000 rows, 50 columns, 256 KiB; first 50 failures. No formulas, cross-column rules, fact checking or data repair.

Store memories from a conversation, like mem0's add: an AI model extracts durable facts about the user from the messages (or, with infer=false, stores each message as is), embeds them and saves them privately under your memory_key (a secret string you generate; required). Identical facts are stored once. Needs at least one of user_id, agent_id, app_id, run_id. Memories are kept for 365 days. Returns {event_id, status, results:[{id, memory, event: ADD|NONE}]}.

Search your stored memories by meaning, like mem0's search: embeds the query and returns the closest memories with a relevance score from 0 to 1. Only memories stored under the same memory_key (your secret string; required) are searched. filters must name at least one of user_id, agent_id, app_id, run_id. Returns {results:[{id, memory, score, metadata, ...}]}.

Delete your stored memories, like mem0's delete memory and delete all memories. With memory_id: deletes that one memory (404 if it is not yours). Without it: deletes up to 200 of your memories matching user_id, agent_id, app_id or run_id (at least one), and says if more remain. Requires your memory_key (a secret string you generate): other keys cannot delete your memories.

Store a persistent key-value memory for an AI agent (namespace-isolated, optional TTL and metadata). Returns the stored memory record as JSON.

Takes a message history and a character budget and returns a shortened history together with a full account of what it cost. Four stages run in fixed order: pin protects messages that must survive (roles listed in keep_roles, the last keep_last_n messages, and anything you marked pin), dedupe removes later near-duplicates of an earlier message of the same role using word-overlap similarity, trim shortens unprotected survivors to max_message_chars at the last sentence boundary, and drop removes…

Replaces private-key blocks, credential assignments, email addresses, Luhn-valid payment-card candidates, IPv4 addresses and phone-like digit strings, returning only sanitized text and per-category counts. The request archive stores only input field names and the result archive stores only this method via the endpoint factory. Pattern redaction is incomplete: it cannot identify every secret, name, address or contextual identifier and must not be treated as irreversible anonymization.
