Every agent-payable API.

Preview the Hyperliquid cancel action the user must sign for an open numeric order ID. Treat spot and perp as one balance only when the account abstraction mode is "unifiedAccount".

Prepare a user-signed abstraction change: disabled, unifiedAccount, or portfolioMargin. Sign with the account owner's wallet, then submit using the returned submitPath. Treat spot and perp as one balance only when the account abstraction mode is "unifiedAccount".

Prepare a USDC-only withdrawal to the signing account; other assets return 400. Unified account and portfolio margin accounts must use spot; manual mode may use spot or perp. Arbitrum receives the amount less a fee, and gas comes from the balance left, so the whole balance cannot be withdrawn. Sign the typedData and submit it unchanged to submitPath. Treat spot and perp as one balance only when the account abstraction mode is "unifiedAccount".

Return the Hyperliquid noop action the user must sign to mark a nonce as used for safer in-flight cancellation workflows. Treat spot and perp as one balance only when the account abstraction mode is "unifiedAccount".

An event and every market under it. The venue's grouping of markets: every line of a match, or the mutually exclusive outcomes of a multi-outcome question (`negRisk: true` means exactly one of them resolves Yes). Markets come back in the search-result shape (outcome tokenIds, tradability, fees), each with the venue's short `label` when it has one. Reach an event from any market's `eventId`; an unknown id is a 422.

Prepare an order for L1 signing with the configured lowercase builder and fee in tenths of a basis point. Sign and submit unchanged to the returned submitPath. Missing builder configuration returns 503. Treat spot and perp as one balance only when the account abstraction mode is "unifiedAccount".

Prepare the selected bridge route as ordered unsigned transactions: an exact-amount ERC-20 approval when needed (after an approval to 0 for tokens like Ethereum USDT), then the bridge transaction. Pass the minTargetAmount and maxNativeFee the user accepted; if the fresh quote delivers less or charges more native fee, it returns 409 with quote { adapter, estimatedTargetAmount, minTargetAmount, nativeFee } and no actions. Send the actions before expiresAt.

Select the best available swap quote and return ordered unsigned transaction actions. Run the returned actions in order: up to two approvals, then the swap.

Return chart-ready Hyperliquid portfolio graph data for account value, PnL, drawdown, deposits, and withdrawals. Treat spot and perp as one balance only when the account abstraction mode is "unifiedAccount".

Audit Hyperliquid open orders for stale, duplicate, conflicting, reduce-only, or unprotected orders. Treat spot and perp as one balance only when the account abstraction mode is "unifiedAccount".

Produce an agent-ready Hyperliquid portfolio report covering equity, PnL, leverage, margin health, liquidation exposure, and concentration. Treat spot and perp as one balance only when the account abstraction mode is "unifiedAccount".

Prepare a batch redeeming resolved positions to pUSD; `conditionId` narrows it to one condition. `plan.plan.details.conditions` lists what this batch redeems. Protocol V2 positions go in a batch of their own: when CTF positions are redeemable too, this batch carries those and `plan.plan.details.pendingConditions` lists the V2 conditions for the next prepare. V2 outcomes that pay nothing are skipped. 422 when nothing is redeemable.

Construct a prediction-market order; never submits. `account` is the signer EOA; by default the maker is its deposit wallet (signatureType 3). Requires `credentialToken` from /predict/polymarket/credentials. Returns `construction` and a signature action the chainhilt wallet signs and POSTs to /predict/polymarket/orders/submit. Review orderSummary and warnings before signing: `estimatedBuilderFee` (ours) and `estimatedVenueFee` (Polymarket's) are pUSD on top of the principal.

Deploy the deposit wallet, then add its missing trading approvals, one step per call. Requires the signer's `credentialToken` (401 once revoked). Undeployed: `plan.plan.details.step` is "deploy"; the wallet signs and POSTs the action to /predict/polymarket/wallet/batch/submit, then calls again (202 while pending). Deployed: a Batch of the missing approvals for the same route. 422 "Nothing to onboard" is not charged; GET /predict/polymarket/wallet/{signer} checks for free.

Detect high leverage, liquidation proximity, concentration, funding drag, and missing stops for a Hyperliquid account. Treat spot and perp as one balance only when the account abstraction mode is "unifiedAccount".

Use this as a lighter-weight fraud signal than check_carrier_identity: how many distinct business addresses and phone numbers a carrier reports across FMCSA's independent records of it (census, licensing and insurance, crash reports). Several different addresses on one carrier is a common re-registration tell. Billed whenever the USDOT number resolves.

Use this to check one applicant carrier against a roster of carriers you already work with — e.g. catching one you previously cut for a revocation or suspension trying to re-enter under a new USDOT number. Returns whether it's linked to any roster member and which ones, never a carrier outside your own roster. Metered: a base price plus a per-roster-entry price, both shown in get_catalog; billed whenever the applicant resolves, whether or not it matches anything on your roster.

Use this to check a freight broker before you accept a load or extend credit: whether it holds active broker authority, its broker dockets and how current each status is, its bond (BMC-84/85) continuity and lapses, its authority history (grants, revocations, suspensions, reinstatements) and the identity linkage screen. Give an MC number or a USDOT number. A record, not a recommendation. Billed whenever the broker resolves, including when it holds no broker authority.

Use this when a carrier looks suspicious — a name change, a new USDOT number tied to an old fleet, a business you suspect re-registered after a revocation — and you need the full evidence: every other USDOT number sharing a contact identifier with it, and whether any of them carries a revocation or suspension motive. Call the free screen_carrier_identity first if you only need the flag and a count. Billed whenever the USDOT number resolves, even with no links found.

Use this to find which carriers on your own list changed on or after a date, and what changed: authority, insurance, out-of-service and other tracked fields, each with old and new values. Metered: a base price plus a per-roster-entry price, both shown in get_catalog; billed whenever at least one roster entry resolves, even if nothing changed. As fresh as the last data refresh.

Static security scan of a CI/CD pipeline config: GitHub Actions, GitLab CI or CircleCI. Detects unpinned actions / images / orbs, template and environment injection, dangerous triggers, over-broad workflow-token permissions, secrets leaked to logs, cache poisoning and more. Returns a verdict (pass, caution, block), a 0-100 risk score and per-finding rule, severity, object, location and a concrete fix hint. Security indicators, not a guarantee.

Jev-powered research: routed search, cited answer, claims verified against sources. Ask a question, get a 5-8 sentence answer, each claim tagged to a numbered source, built from real page content - no invented facts. A fast paid LLM writes it, under 4.5s guaranteed; on a rare miss, a no-LLM extractive fallback (top sentences from the sources, picked by Jev) takes over instead, marked "synthesis":"extractive". Try GET /research/sample.

Check whether a source supports, contradicts, or gives insufficient information about a claim - a typed verdict with a real probability, not generated text. Try GET /verify/sample.

Claude Sonnet API - pay per call, no API key. OpenAI-format chat completions on anthropic/claude-sonnet-5.5, pinned to Anthropic's own OpenRouter endpoint for reliability. You sign a fixed price computed from your max_tokens; unused tokens are not refunded. 20s server-side timeout - never charged if it fires; set your client timeout to 30s. Try GET /llm/claude-sonnet/sample.

A registry of token records with a build log. A record is written only by the token's provable controller (on Solana: the pump.fun curve creator or the mint's update authority) and every version carries that ed25519 signature, so a reader verifies against the chain, not a directory. One $0.02 x402 write in USDC on Base, Polygon, Solana or Arc; reads, pages, log and OpenAPI are free.

BTC spot regime check against a 7-day moving average: returns bull or bear, MA7, deviation percent, and a favor-entry or block-entry action. Use when an agent must gate a BTC entry before sizing.

Scores a domain's AI-agent readiness: robots.txt, llms.txt, mcp.json, structured data. Returns pass/fail findings and a 0-100 score.

AI-scored resume evaluation against a job description: dimension scores, verdict, and explicit judge-failure warnings. $0.05 per evaluation in USDC on Base via x402.

Static application-security scan of a single code blob for CWE Top-25 logic bugs (SQL injection, XSS, command injection, SSRF, path traversal, insecure deserialization, weak crypto and more). Pass the code and its language; returns a verdict with per-finding CWE, severity and line. Static indicators, not a guarantee.

Static application-security scan of source code or a git-diff for CWE Top-25 logic bugs: SQL injection, XSS, command injection, code and template injection, SSRF, path traversal, insecure deserialization, weak crypto, insecure randomness, open redirect and XXE across Python, JavaScript, TypeScript, Java and Go. Returns a go/no-go verdict with per-finding CWE, severity, file and line. Static indicators, not a guarantee.

cogDepot agent marketplace API. Paying any offer buys credits for the paying wallet's account; a first payment creates the account.

commodities.sh price

Use this when you already suspect two specific carriers (by USDOT number) are the same operation under different paper and want it confirmed, without receiving any information about a carrier you didn't name. Returns only linked true/false and, when true, the shared cluster_id — never a member list. Billed whenever both USDOT numbers resolve, whether or not they turn out to be linked; supplying the same number twice is free.

Risk check for an EVM contract/token address

Is a claim independently corroborated across multiple unrelated sources, or does it trace back to a single origin? Groups matches by SOURCE (not category) so a caller sees exactly how many independent outlets/agencies back a claim -- a trust signal no single-source competitor can offer, since it requires already owning many independent sources.
