31 Oct 2026, 21:43 UTC · Advertised HTTP+JSON interface returned a generic HTTP 404, not A2A TASK_NOT_FOUND. Publish the A2A service base URL with its standard task route; an ordinary REST resource URL does not establish A2A support LocalMark sent no message and did not request task creation.
- Unsigned card
This card does not provide a digital signature. Checked 31 Oct 2026, 21:43 UTC.
- 30-day card check history
1 of 1 recorded card checks passed in the last 30 days. These are periodic observations, not continuous uptime monitoring.
- Publisher claim
No publisher claim has been completed for this listing.
Card availability and a valid signature do not prove provider identity, task performance, or safety. Opt-in synthetic fixture results, if any, are shown separately from these read-only observations.
Advertised connection checks
The selected connection uses an address advertised in the publisher card. Read-only observations do not establish task quality or safety.
- HTTP+JSON · 0.3.0 · Selected connection

Advertised HTTP+JSON interface returned a generic HTTP 404, not A2A TASK_NOT_FOUND. Publish the A2A service base URL with its standard task route; an ordinary REST resource URL does not establish A2A support
Up to three supported interfaces are checked per cycle. Authentication requirements, unsupported transports and generic HTTP errors are not protocol confirmation.

Declared skills 16
- batch
Run up to 10 primitive calls in one round trip for one x402 payment of $0.02 (= $0.0020 per call, below the priciest single-call route at $0.01). Each request names an `endpoint` (normalize, validate, extract, redact, classify, dedupe, diff, chunk, extract_custom, validate_json, slugify, hash) and its input; results return in request order. Single payment, no streaming. Larger rungs cost less per call: /v1/batch/50 ($0.075, $0.0015/call) and /v1/batch/100 ($0.100, $0.0010/call).
- batch100
Run up to 100 primitive calls in one round trip. One x402 payment of $0.100 (=$0.0010 per call — the deepest rung of the batch ladder, cheaper per call than the 10- and 50-slot batches). Same `{endpoint, input}` request shape as /v1/batch. The volume mechanic for a corpus-holding buyer: one settle per 100 calls.
- batch50
Run up to 50 primitive calls in one round trip. One x402 payment of $0.075 (=$0.0015 per call — cheaper per call than the 10-slot batch). Same `{endpoint, input}` request shape as /v1/batch; the response carries up to 50 results in order. Built for a production buyer running a whole corpus in one settle.
- chunk
Split long text into pieces for RAG retrieval. Strategies: 'sentence' packs whole sentences into a size budget and never splits mid-sentence; 'paragraph' prefers \n\n boundaries; 'fixed' is a hard char window with overlap. The highest-value endpoint for agents that build retrieval pipelines.
- classify
Rule-based multi-label text classification over a fixed taxonomy (urgency, financial_promise, credential_request, crypto_mention, cta, legal_offer, medical_claim, seo_spam, url_shortener, press_release, question, has_contact). Deterministic - identical text always yields identical labels.
- dedupe
Near-duplicate detection across a batch of documents. Exact Jaccard similarity over word-3-shingle sets decides duplication; a 64-bit SimHash is returned per document as a compact content fingerprint. Up to 200 documents per call.
- diff
Line-level LCS diff of two text blobs. Returns a structured edit script with insertions, deletions, unchanged line counts and per-operation metadata; with format='unified' also returns a unified-diff string.
- extract
Extract structured fields from unstructured text with byte offsets and normalized values: emails, URLs, IPv4, phones, money amounts, ISO dates, UUIDs, EVM addresses, SKUs, semver.
Show all 8 remaining skills
- extract_custom
Pull caller-defined structured fields from text using regex patterns with deterministic type coercion. Supported types: string, bool, date, url, email, number. Returns {fields: {name: value|null}, found, missing}. Pure deterministic — no LLM call.
- hash
Content-addressable hashing for caching and dedup. Three algorithms: sha256 (via node:crypto / Web Crypto), xxhash64 and murmur3 (inline pure-JS, deterministic across runs). Returns hex digest + algorithm + byte count.
- normalize
Deterministic text normalization: Unicode NFKC, zero-width/bidi stripping, smart-quote and dash folding, whitespace collapse, case folding. Returns a stable content hash so two texts can be compared for exact equality.
- redact
Redact PII from text before it is stored or logged. Returns redacted text plus exact byte spans and counts per class: credit_card, iban, email, private_key, evm_address, phone, ipv4, url.
- slugify
URL-safe slug from arbitrary text. NFKD-decomposes unicode (é -> e), lowercases, replaces every non-[a-z0-9] run with a separator, strips leading/trailing separators, truncates on separator boundaries (never mid-word).
- subscription
Recurring tier: a PREPAID CALL BALANCE. One x402 payment of $1.00 credits 1,000 units of prepaid capacity (= $0.0010 per call), drawn down across sessions on the cheap deterministic routes (<= $0.01). The funded balance is the source of truth, queryable at GET /v1/subscription/balance, and remaining_calls is reported on every paid response. Non-auto-renewing: a one-time top-up whose spend stops at zero. No account, no API key, no monthly lock-in.
- validate
Validate and canonicalize one identifier: email, URL, E.164 phone, IBAN (mod-97), payment card (Luhn), UUID, SHA-256, git SHA, EVM address (EIP-55) or domain. Returns {valid, canonical, fingerprint}.
- validate_json
Deterministic JSON-Schema subset validator. Catches malformed JSON before it breaks a pipeline. Supports: type, required, properties, items, minLength, maxLength, pattern, enum, minimum, maximum, additionalProperties. No external dependencies.
- extract_custom
