VAULT POSITION (on-chain read): current redeemable value of a wallet's ERC-4626 vault position. Pass the pool_uid (from barker_executable_pools / barker_execution_quote) and the wallet address; Barker resolves the vault contract and reads balanceOf + convertToAssets directly on-chain, returning shares and current_value in the vault's underlying asset (value_asset, e.g. USDC).…

Live analyst read on a MACRO instrument — indices, rates, commodities (?asset=SPX, VIX, US10Y, US2Y, GOLD, OIL, BRENT): sentiment, dominant narrative and divergence vs price. An analyst verdict on macro, not a raw data dashboard. Descriptive research, not financial advice.

Deep-dive on a tracked market theme/narrative (?theme=ai-sentiment-divergence, altcoin-decoupling, macro-risk-off, regulatory-pressure, tradfi-adoption, or free text): is it strengthening or fading, which assets it moves, and the desk's read. Descriptive research, not financial advice.

Dominant narrative on one crypto asset and whether it rotated in the last 24h (?asset=BTC) — narrative-change detection for trading agents. Descriptive research, not financial advice.

Sentiment-vs-price divergence read on a US STOCK ticker (?asset=NVDA): social sentiment %, dominant narrative, prediction-market context and any divergence from price action — a live analyst verdict on equities, not raw filings data. Descriptive research, not financial advice.

Market-wide crypto regime read in one call: overall sentiment score, regime id, macro anchor and the top narrative driving the whole market right now. Live analyst read, not a cached aggregate. Descriptive research, not financial advice.

Cheapest entry point: the latest cached analyst signal for one asset — sentiment %, stance, divergence flag, narrative — with an age timestamp (?asset=BTC). Cached-only, no freshness guarantee: for a guaranteed-fresh read use /v1/consensus. Descriptive research, not financial advice.

Anything happening on this asset right now? Live probe for significant triggers — price gap, news shock, social spike — with a 1-10 significance score, or a clean no-event answer (?asset=BTC). Built for agent polling loops that only want to act when something moves. Descriptive research, not financial advice.

Cross-asset divergence screener: every asset the desk covers with its latest cached sentiment %, stance, divergence flag and signal age in ONE call (?only=divergent to filter). The which-asset-should-I-look-at-first question no single-asset API answers. Cached-only. Descriptive research, not financial advice.

Price-vs-sentiment trajectory for one asset over a window (?asset=BTC&window=7d): how tape and crowd moved together or apart, and whether the move is strengthening or fading. Descriptive research, not financial advice.

Market-moving news read for one asset (?asset=BTC): what just happened, why it matters, and the sentiment read on it — analyzed by a live desk, not a raw headline feed. Descriptive research, not financial advice.

A falsifiable analyst prediction for one asset (?asset=BTC&horizon=7d): the claim, a confidence %, what would prove it wrong, and prediction-market anchoring. Pair with /v1/track-record to audit how past calls resolved — no other API sells accountable machine predictions. Descriptive research, not financial advice.

The analyst desk's current thesis and conviction on one crypto asset — house view with confidence from tracked insight threads (?asset=BTC). Descriptive research, not financial advice.

Live prediction-market odds for one crypto asset — nearest liquid market, % odds, venue — plus whether the odds agree with current social sentiment (?asset=BTC). Descriptive research, not financial advice.

Social sentiment read for one crypto asset: bullish %, social score, and volume trend vs baseline — crowd positioning in one call (?asset=BTC). Fresh from the desk, priced under every comparable sentiment endpoint. Descriptive research, not financial advice.

Cached signal history for one asset (?asset=BTC, up to 50 rows): timestamped sentiment %, stance, divergence flags and narratives — backtest-ready analyst history no raw data API sells. Descriptive research, not financial advice.

Task router: describe what you need in plain text (?task=...) and get the exact Vedetta endpoint, parameters and price to call — plus cheaper cached alternates. Stops agents guessing or overpaying. Half a cent, instant, never fires a live analyst read. Descriptive research, not financial advice.

Dutch vehicle lookup by kenteken (registration, fuel, APK). Send the kenteken in a JSON request body via POST. Payment constitutes acceptance of the terms at https://agenticweb.nl/terms.

Vehicle Identification Number validation (ISO 3779): 17-char structure, check digit (position 9), WMI/VDS/VIS decomposition and model-year code.

Check agent deliverables for required sections, limits, placeholder or forbidden text, source minimums, citation wiring, and claim traceability.

Generates an AGENTS.md for a public GitHub repository — the file coding agents read on task start. Contains build/test commands quoted from the repository's own manifests with the source file named, a directory map, entry points, and edit boundaries. Every path is checked against the git tree; ambiguous areas are marked 'unverified' rather than guessed. Returns markdown.

Deterministic analysis of a public GitHub repository. Returns layout, language breakdown, toolchain commands with their source manifest, test and CI presence, a 0-100 documentation-health score, and phantom_paths (file paths the README cites that do not exist). No language model is used, so results are reproducible for a given commit.

Verifiable Random dice — unbiased dice rolls bound to a future drand round the server waits for (typically 3-6s) and verifies locally, with a reproducible proof transcript.

Verifiable Random pick — string selection with or without replacement bound to a future drand round the server waits for (typically 3-6s) and verifies locally, with a reproducible proof transcript.

Verifiable Random shuffle — a uniform Fisher-Yates permutation bound to a future drand round the server waits for (typically 3-6s) and verifies locally, with original indices and a reproducible proof transcript.

Cryptographically-secure randomness with a receipt. GET ?bytes= returns hex (1-256 bytes); add ?min=&max= for a uniform integer in an inclusive range. Each response carries a request_id and timestamp — unbiased entropy an agent can cite to a counterparty, not a seeded PRNG. Need provable fairness over time? /rand/commit does commit-reveal (commitment now, value later).

Verify Product data against multiple representations on the requested page. Returns field-level corroboration, bounded evidence, contradictions, observation time, and a content hash. Outcomes: verified, conflicted, or insufficient_evidence. Non-product pages return 422 and do not settle. $0.02 USDC per successful result on Base.

Use when an agent needs to publish a multi-file HTML/CSS/JS site to a public URL without an account or API key. It verifies index.html, linked assets, and required selectors before publishing. Intro price is 0.01 USDC per successful publish until August 16, 2026 or 3 third-party payers. Failed checks neither publish nor settle payment. Successful releases are versioned for rollback.

Verified-routed web search / extract — best real provider, 10% over its price

Verify a French contractor before hiring: company health, age, RGE certification, insolvency proceedings, trust level. Query: ?q= or ?siren=

Verify a single email: syntax, MX records, SMTP RCPT probe, catch-all, disposable, role-based, free-provider, typo suggestion, 0-100 score, and verdict.

Verify a single email address for deliverability. Returns a search ID to poll for results via the Fetch Search Result endpoint.

Multi-region real-device uptime/performance check for a domain (default NA/EU/APAC, via UpRock Verify): per-region reachability, Core Web Vitals (LCP/FCP/CLS/TTFB), total load time, and screenshot-captured proof -- not a synthetic/datacenter check, run from UpRock's real residential/mobile device network.

Verify whether a public listing page currently supports a buyer-supplied availability, price, and location claim.

Re-resolve an attested settlement against the venues right now and report whether it still holds: CONFIRMED, CHANGED, or INDETERMINATE. Exchanges revise candle history and outages end, so an attestation proves what was said while only a fresh resolution proves it is still true. Pass a decision_id issued by /v1/oracle/attest.

Verify an email address. Uses one verifier credit on all attempted verifications.

Verify Badge (CDP-settled mirror) — an embeddable badge backed by a FREE live re-check, so it proves a standard holds now, not just once. The re-check is our advertising.

Verify whether a cited source supports an exact factual claim

Verify Claim (CDP-settled mirror) — check a target against one machine-checkable standard and get a signed, re-checkable certificate only our key can issue. Digital only; a physical claim defers to human review, never a fabricated pass.

Verify an x402 purchase actually settled and delivered what you paid for: submit bounded, non-secret metadata for the payment requirement, payment response, delivery receipt and settlement reference, and receive a single deterministic verdict — proven, conflicting, or missing — field by field, suitable to attach to a refund request or dispute. Limitation: verdicts are computed from the artifacts you provide; we do not fetch chain state or contact the provider on your behalf.

Verify any third-party x402 endpoint is alive and correctly configured before paying it: a bounded GET/402 preflight fetches the payment contract, checks reachability and response latency, validates accepts, network, price and expiry against the x402 spec, and returns a signed observation receipt with an observed_at timestamp you can cite — protection against ghost endpoints, dead quotes and wasted USDC. Limitation: no payment is made, one endpoint per call, and a passing probe proves the contr…

Verify if a person meets a minimum age requirement based on their date of birth. Returns exact age, whether the threshold is met, and days until the threshold (if not met). Accounts for leap years.

Verify the deliverability of an email address.

Historical time series of the x402 Bazaar, reconstructed from daily snapshots taken since launch. Returns per-day ecosystem GMV, merchant and listing counts, price-band distribution and median/P90 pricing; per-merchant lifecycle with first-seen, last-seen and departure; every observed price change with date and magnitude; and the biggest movers ranked by change in unique paying wallets. The discovery API exposes only the current catalogue - this is the archive of what it used to look like.

Authenticity scoring for x402 listings: separates genuine demand from self-traffic by comparing unique paying wallets against call volume. Adds price-band guidance from what measurably sells, your revenue percentile against all indexed merchants, and per-listing health diagnostics. Free field-level check: /api/audit/listing-health.
