What is trending right now: the most-read Wikipedia articles for a language and day (default yesterday UTC), with views and rank, cleaned of the Main Page, special and other non-article pages. A daily signal of trending topics, breaking news and current events in 300+ Wikipedia language editions. Suited to trend discovery, news monitoring and content ideas.
workers.dev-$0.005listed

x402pulse.dev-$0.002listed
Trending and newly profiled
What Solana tokens are being pushed right now: DexScreener's top boosted tokens (paid promotion, ranked by boost amount - a signal of marketing spend, not quality) and the latest token profiles (fresh listings with a filled-in profile), both filtered to Solana. Each row carries the mint, DexScreener URL, description snippet and links. Feed the mints into sol-token-safety to separate the promoted from the sound. Keyless; two small DexScreener reads in parallel.

Generate a video from a text prompt, or animate an image_url from its first frame. The paid response waits about as long as the model usually takes to render and returns the video URL, else a statusUrl to poll (Prefer: wait=N sets the wait). 8 models including Google Veo 3.1, Kling 3.0, Seedance 2.5, Wan 2.7 and MiniMax Hailuo 3, 4 to 15 seconds, 16:9 or 9:16, from $0.42.

Trial Eligibility API
Retrieves the eligibility section of a registered trial and separates it into inclusion and exclusion criteria as individual items, each classified where the classification is unambiguous and each carrying the verbatim source sentence. The source sentence is the substance rather than a nicety: eligibility criteria decide whether a person can enter a study, a structured item without its origin cannot be checked, and a wrongly structured one goes unnoticed.
halowerk.com-$0.006listed
Trial Finder API
Searches the clinical trial registry and returns matching studies with the fields that decide whether a trial is relevant: the recruitment status translated from the registry code, the phase, the study type, the enrolment target, the conditions and interventions, the sponsor, the start and completion dates, and the countries with sites.
halowerk.com-$0.006listed
Trial Sites API
Returns the participating sites of a registered trial, each with the facility name, city, state and country, the coordinates the registry holds, the recruitment status of that site specifically, and any publicly listed contact. Site status is reported separately from trial status and that separation is the point: a trial can be recruiting overall while the nearest site has stopped, and the reverse happens too, so applying the trial status to every site sends someone to a closed door.

Trip Check API
One-call go / caution / avoid verdict for a drive from A to B: road closures and delays on the route, destination weather, nearby stays and volcano/earthquake alerts. Use for a complete trip readiness check instead of several calls. If the name is unusual, call /resolve?route=A to B (or /resolve?place=...) first (free); a failed lookup is still charged.

Trip Check API
Trip check: one call rates the delay risk (low, moderate, high) for a flight between two airports on a date, with plain-language reasons. Combines live FAA delays and ground stops, current airport weather and airport forecasts for both ends, the destination's State Department travel advisory, and the currency exchange rate for international trips. Any airport worldwide by IATA code, e.g. SFO to LHR. Not for flight planning.
x402pulse.dev-$0.03listed
Trip Impact Check API
Check a Japan itinerary [{date, prefecture}] against JMA warnings/advisories in effect now. Per stop: matched_advisory (with severity), no_match_in_checked_sources (NOT a statement of no impact) or unknown (data missing, or date not today/tomorrow JST). Returns checked sources and areas, unchecked areas, issued_at, retrieved_at, and current JMA typhoon/volcano bulletins (listed, not matched). No forecast. Retrying with the same payment is not charged; use receipt_id with get_receipt.
workers.dev-$0.03listed
Trip Metrics API
Takes an ordered list of positions with timestamps, optionally carrying the battery state of charge at each fix, and returns what a fleet operator asks of a trace: total distance over ground, how much of the elapsed time the vehicle was moving and how much it stood, each individual stop with its position and duration, the mean and maximum speed, and — where a battery capacity is supplied — the energy drawn and the consumption per kilometre.

Tron USDT Address Check
Tron address check: TRX balance and staked TRX, USDT and USDC (TRC-20) balances, USD value, when the account was created and last active, bandwidth and energy, and warning signals (never activated, created in the last 7 days, smart contract instead of a wallet). Use before sending USDT on Tron or to check a counterparty; fresh or never-activated receiving addresses are typical for scams.
agentsvc.io-$0.002listed
Tron USDT Transfer Watch
Watch a Tron address for USDT and USDC (TRC-20) transfers in a loop: each call returns only transfers since your last call with amount, direction, counterparty, time and link, plus the TRX balance. First call covers the last hour (lookback_hours up to 6) and returns a cursor; pass it back next time. For deposit detection and payment confirmation on Tron.

One organization's full subprocessor list (name, URL, purpose, location, AI flag, provider_id), its security and compliance hiring role titles and the frameworks they name, and the frameworks it lists as in progress, planned or on its roadmap. `status` is null when the organization does not say which.

workers.dev-$0.003listed
Trust Check For Any X402 API
Trust check for any x402 pay-per-call API URL. Live-probes the target: verifies a valid 402 payment challenge, consistency between the challenge and the /.well-known/x402 manifest, payTo address validity, price sanity, Bazaar listing status, and TLS basics. Returns a GO / CAUTION / STOP verdict with reasons.
workers.dev-$0.05listed
Trust Receipt Verify API
Verify a BlindOracle receipt against the parts a buyer cannot check alone: is the proof_id really in BlindOracle's append-only proof rail, does its payload still hash to the stored row, and does the row's HMAC-SHA256 verify against the signing key. Also recomputes content_sha256 and confirms the Base payment, so one call is a complete answer. Deterministic, no LLM. The self-checkable half is free forever in the published verify-blindoracle-receipt skill (RQ-BO-RECEIPT-VERIFY-01).

TrustAgent
Is this counterparty safe to pay? Screens the address against the OFAC sanctions list, reads its ERC-8004 reputation with coordinated feedback filtered out, and returns an explainable 0-100 trust score with a proceed / hold / block recommendation. Reports insufficient_data rather than guessing when the evidence is not there.
trust-agent.io-$0.002listed
TrustAgent
What is this agent's reputation actually worth? 92.6% of ERC-8004 feedback on Base is coordinated. This clusters reviewers by funding provenance and caps each cluster at one effective vote, returns every record with its evidence class and flag reasons, and refuses to average ratings that use incompatible scales.
