Every agent-payable API.

Music generation: describe a track, get an original piece back in the same response. Google Lyria 3: a 30-second clip ($0.06) or a full song ($0.12). No account or API key: the payment is the only credential.

Narrated short video from a topic: a finished 30-second vertical (9:16) video with a written script, four scenes, an ElevenLabs narrator, a music bed, captions and callouts, plus a title and description. Animated scenes (Veo 3.1 Lite) $3.22, or stills $0.87. No account or API key: the payment is the only credential.

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. GET this URL for every model and price. No account or API key: the payment is the only credential.

Text to speech: send text, get a natural voiceover MP3 back in the same response. ElevenLabs Eleven v3 (expressive, takes [whispers]-style directions) or Multilingual v2 (29 languages), 13 voices, up to 3000 characters, $0.42 per 1,000 characters. GET this URL for the voices. No account or API key: the payment is the only credential.

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.

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.

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.

Trigger an event to all webhooks

Come in. Have a coffee. Check the weather. Then go to work. High-importance crypto news (24h) with correlated Chainlink deviation fires. Each news item with importance>=7 shows oracle_events that fired within 120s. ~20% of oracle fires correlate with news. Use to see WHY Chainlink moved, or to anticipate post-news oracle lag.

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.

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.

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.

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.

Seoul concert trip pack, in Japanese (default), English or Korean (lang=ja|en|ko): concert detail, tickets incl. global sites, venue + map, nearby hotels/food/spots, same-week festivals, yen prices — ¥50

Paid x402 endpoint for generating AI-powered trivia questions.

Live gas prices per chain — Base, Ethereum, and Solana from public RPCs, with speed tiers where derivable, plus a cheapest-chain recommendation. Toll: $0.02 USDC on Base or Solana.

Free-to-enter sweepstakes with real prizes, verified live. Toll: $0.02 USDC on Base or Solana.

TRON (TRX) price in USD now, with 24h and 7d change — Genesis402 / UnyKorn Operator Network

Tron DeFi overview: TVL trend, top protocols, stablecoins, DEX volume, fees — Genesis402 / UnyKorn Operator Network

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.

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.

Custom-weight rerank of every cryptocurrency covered by True Value Rankings: the full TVR table recomputed with the caller's own weights for the 8 fundamental metrics, using TVR's non-public score transformation. $0.05 USDC per call. Educational model output, not a recommendation.

Truncate text with ellipsis for $0.001 USDC. Call when you need this bounded result without an API key or subscription. Returns machine-readable JSON via x402 on Base or Solana. Limitation: results cover only the supplied input or one bounded public endpoint at request time; callers must verify before acting.

Check any wallet on-chain activity and risk level before transacting

Should an agent click, sign in to, or pay this domain? A risk score and verdict (likely_safe / caution / high_risk, or inconclusive when a check could not run) with plain-English reasons, from domain age, spam/abuse blocklists and the HTTPS certificate.

One organization's public tier as on its profile page: timeline, posture checks, published controls, BAA claim, advertised frameworks, subprocessor and AI-provider counts, chain-trust ratio and hiring count. Price: $0.01 flat per profile.

Every directory organization that publicly lists at least one AI provider as a subprocessor, with the AI providers each one lists, sorted by organization name. Price: By list size band: 10-99 orgs $5.00, 100-499 orgs $7.50, 500-999 orgs $10.00, 1000+ orgs $15.00. Lists under 10 orgs are not sold. Quotes above $1 need maxAmountPerPayment raised in the x402 client's spend controls.

Every directory organization that lists this framework as in progress, planned or on its roadmap, with the status each one states, sorted by organization name. `status` is null when the organization does not say which. Price: By list size band: 10-99 orgs $10.00, 100-499 orgs $15.00, 500+ orgs $25.00. Lists under 10 orgs are not sold. Quotes above $1 need maxAmountPerPayment raised in the x402 client's spend controls.

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. Price: $1.00 covering up to 10 subprocessors, +$0.05 per subprocessor beyond 10, capped at $5.00. Quotes above $1 need maxAmountPerPayment raised in the x402 client's spend controls.

Every directory organization that publicly lists this provider as a subprocessor, with the purpose each one states, sorted by organization name. Price: By list size band: 10-99 orgs $5.00, 100-499 orgs $7.50, 500-999 orgs $10.00, 1000+ orgs $15.00. Lists under 10 orgs are not sold. Quotes above $1 need maxAmountPerPayment raised in the x402 client's spend controls.

Is this address safe to send funds to on Base? Checks scam blacklists, address poisoning (look-alikes of your recent counterparties via ?from=), token contracts, burn and never-used addresses. Returns a verdict with reasons.

Is this Base token safe to buy? Simulates a real buy and sell (honeypot + hidden tax test), checks owner powers (mint, blacklist, fee changes), whale concentration, liquidity lock and scam lists. Returns scam / high_risk / caution / low_risk with reasons.

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.

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).

Full trust report for an x402 endpoint (same as GET /v1/report): score breakdown, current quote, wallet/price events, and paid delivery checks.

Which live agents can do X — and which of them are safe? Searches the skills, domains and names ERC-8004 agents declare, across the registrations this service sweeps continuously, and returns only the ones answering. Each row carries the endpoint to call, the wallet a payment reaches, and that wallet's risk band and sanctions verdict, so choosing between candidates is one call rather than a screening per row. Free alternative: GET /v1/search. Trial: 3 free calls/wallet/24h — https://trust-agent.io/v1/trial.

Is this x402 endpoint safe to pay? Reads the endpoint's own payment challenge under BOTH protocol versions — v1 body and v2 PAYMENT-REQUIRED header, so a live v2-only service is not reported as dead — extracts the payout wallet it advertises, and screens that wallet: OFAC sanctions, sybil-filtered ERC-8004 reputation, on-chain behaviour. Flags an endpoint that names different recipients under the two versions. Scores the wallet, not the service behind it, and says so.

Should you approve this contract? Everything in quick, plus static analysis of the bytecode: privileged functions (mint, pause, blacklist, arbitrary withdrawal), proxy and upgradeability detection, dangerous opcodes, DeFi protocol classification and source-verification status.

The filtered ERC-8004 directory: which registered agents are actually alive, and which accept x402. Roughly 15% of registrations on Base have both a compliant registration file and a declared service — this returns those, rather than making you screen sixty thousand addresses one at a time to find them. 100 agents per page.

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.

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.

Has anything changed about counterparties you already screened? Re-checks a list of addresses against OFAC designations and delistings since a timestamp you supply, so a verdict you acted on last month does not go quietly stale. Stateless: no watchlist is stored and nothing is sent to you — pass the returned checkedAt back as `since`. Free alternative: GET /v1/watch. Trial: 3 free calls/wallet/24h — https://trust-agent.io/v1/trial.

Has the sanctions feed moved since you last looked? Every OFAC designation and delisting since a timestamp you supply, with no address list to send — match the feed against your own counterparty book locally, so the service never learns which addresses are yours. The trivial cron: poll this, pass the returned checkedAt back as `since`. Free alternative: GET /v1/watch. Or 3 free calls of this endpoint per wallet per 24h: https://trust-agent.io/v1/trial.

Trust check an npm package before an agent installs it: typosquat screen, deprecation, package age, maintainers, weekly downloads, source link.

Trusted server time API for AI agents — ISO 8601 UTC timestamp, $0.001 USDC on Base per call. Use when your agent needs reliable current time.
