Higher-confidence evaluation for high-impact, sensitive, or difficult-to-reverse agent actions.

Create an upload session to deploy a new version of an existing project. Call this when publishing an update; it returns a presigned artifact upload URL. Only the project owner wallet can pay.

US Treasury par yield curve, every constant maturity from 1 month to 30 years for a published business day. Returns curve[] with tenor, months and percent, spreads (2s10s, 3m10y, 5s30s) and an explicit inversion flag - the real question is whether the curve is inverted, not what fourteen numbers are. A tenor Treasury did not publish is null, never zero. Pass ?latest=1 OR ?date=YYYY-MM-DD, not both. Errors: 400 conflicting_params|bad_latest|bad_date, 404 no_curve with the available range.

Turn a flat or scanned PDF form into a fillable PDF with detected fields. Also: detect form fields in a PDF; add fillable fields to a document; extract a PDF form schema; make a government or business form fillable. Price scales with page count; this 402 carries the exact amount for the PDF sent.

Converts a datetime from one IANA timezone to another with correct DST handling. ISO-8601 input: bare wall-time strings are interpreted in the from_tz, fully-qualified offsets are honored. DST is handled correctly (uses V8's built-in tzdata via Intl.DateTimeFormat). Returns both formatted strings, both UTC offsets, and the difference in hours. Use it for DST-aware time arithmetic, wall-clock to UTC conversion, or converting across cities.

Live staking yields with liquid staking, liquid restaking (ether.fi/Renzo/Kelp), and best_strategy recommendation. ETH, SOL, ATOM, ADA, DOT, AVAX, MATIC. $0.05/report via x402 on Base.

Check agent outputs for quality issues, inconsistency, and behavioral drift.

Fill a PDF form from structured data such as JSON or key-value answers. Also: fill a PDF form from JSON; populate form fields from data; complete a PDF application from known values; write answers into a form. Price scales with page count; this 402 carries the exact amount for the PDF sent.

Generate one image from a text prompt: app icon, brand logo, character mascot or illustration. POST JSON {description, type?, style?, aspect_ratio?}. type is icon, logo, mascot or illustration (default icon; only icon gets app-icon framing and mask safe margins). style is flat, metallic, 2d-game, clay, 3d, gradient or glassmorphism. aspect_ratio is 1:1, 4:3 or 16:9. Returns image_key and preview_url. No account required.

Convert token units (wei/gwei/ether or arbitrary decimals), between hex and int, and compute/validate an EIP-55 checksummed address.

Signed page read (0.005 USDC): the URL as clean Markdown plus an Ed25519 receipt binding its SHA-256, the provider, and the observation time. Proves what your agent read. Body: {"url": "https://..."}. Sponsored Solana accepts require a payment client that honors accepts[].extra.feePayer (for example @x402/svm ExactSvmScheme); AgentCash cannot settle that Solana rail.

Current gas price and EIP-1559 fee estimate for a chain (base, ethereum, polygon, arbitrum, optimism)

Market scan data: strongest BUY/SELL states across major crypto pairs right now, with confidence. Machine-readable input for AI trading agents (USDC pay-per-call). Free preview: GET /signals/preview Upstream or cache-not-ready returns 503; you are never charged for an error.

Wallet risk score 0-100 with component breakdown for an EVM address.

Parallel Solana risk advisors; flags are not proof of safety. Select ?advisors=a,b from GET /v1/advisors or omit for all. Price = advisor cost + max(US$ 0.005, 15% of advisor cost). Exact prepayment returns 202 charged:true, receipt and job_id/status_url. Advisors run only after the buyer receipt is saved. Poll status_url for free; no second signed request or payment. Paid failures need review, with no automatic refund.

DeFi protocol fees and revenue: total 24h and 7d fees (USD) paid by users across protocols, plus the top protocols by 24h fees with each one's 24h revenue where reported. Optional `chain` filter scopes totals and ranking to one chain.

Risk profile for a Solana wallet acting as a token deployer or operator. Returns a risk level and label, a human summary, and outcome counts over the tokens attributed to it. Counts are served only when the attribution passed on-chain creation verification; otherwise the response is marked 'attribution: unverified' and the numbers are withheld rather than guessed.

Rank blockchains by total DeFi value locked (TVL) across all protocols

Look up a country by name, ISO code, or calling code. Returns ISO codes, official name, capital, region, subregion, and calling codes.

Follow the money out of a wallet. Walks outflows hop by hop under a causal gate (each hop must post-date the last and carry continuous value) until it reaches an exchange deposit, a bridge, a swap venue, or runs out of trail. Returns every hop with its labelled destination, the token-leg outflows alongside the SOL leg, and whether the trail ended at an exchange or a privacy protocol.
