Creates an image from scratch from a text description. Choose the quality tier with image_generator_version: hd, genius, or super_genius for the highest detail at 2k output. The genius tier also takes an art style in genius_preference: classic, anime, photography, graphic, or cinematic. Returns a link to the generated image.

Read a block header by number or the latest, live from Base mainnet, for a fraction of a cent. No API key, no account — a wallet is the only requirement, and you are charged only if the read succeeds. Plain unsigned data; the attested version of chain reads is /v1/oracle/onchain. Answers are read at the moment of the call and stamped with the block they came from where applicable.

Get an inspectable exact solution to a 1-8 variable rational linear system. Returns rank, pivots, particular solution and null space; distinguishes unique, inconsistent and underdetermined systems. No floating-point conditioning or physical-model assessment.

Get Address First Funder Data

Is this token safe to buy? Solana token safety check and token risk score for agents: call before buying, swapping or recommending an unfamiliar token. Risk score 0-100, low/medium/high verdict and plain reasons: mint/freeze authority, liquidity, top holders, dev sold %, snipers, bundles, live sell test, creator rug history. Solana (pump.fun) by default; Base, BNB, Ethereum, Arbitrum via chain=. RugRadar heuristic, may be wrong; not financial advice. 0.01 USDC/call; failed…

Choose a context budget before an agent run. Compare five extractive compilation budgets with token estimates and source coverage. Price basis: five compiler runs, the comparison table and the receipt digest. Uses caller-supplied documents; no answer generation, factual verification or guaranteed token-billing savings.

Read whether an address is a contract, and its code size, live from Base mainnet, for a fraction of a cent. No API key, no account — a wallet is the only requirement, and you are charged only if the read succeeds. Plain unsigned data; the attested version of chain reads is /v1/oracle/onchain. Answers are read at the moment of the call and stamped with the block they came from where applicable.

Geotagged English Wikipedia articles near a point for area reference research, with page, revision, distance, and provenance. Geosearch can return places, institutions, events, or people. Not official, property, resident, screening, or current-condition evidence. Charge-free on no match or source failure.

Local business leads by category and place: checked email (graded A/B/C), contact name when the email shows one, phone, website, socials and buying signals (no website, booking tool, payment system, hiring). Price: $0.03 per lead, flat, with or without an email. 1 to 1000 leads per call (default 10); the 402 quotes the exact total; empty answers are free.

EPA UCMR 5 PFAS results for an address or PWSIDs. EPA service-area point-in-polygon with provider or machine-modeled confidence; containment is not proof of service. Detect and non-detect counts stay distinct; lithium is excluded. Entry-point samples, not a tap reading. Charge-free when unresolved or out of coverage.

Build an astronomy or astrology tool with seven classical-body geocentric longitudes at one UTC instant, Tropical and versioned Lahiri Sidereal frames, conventions and a deterministic receipt. Public or synthetic inputs only. No interpretations, forecasts or predictive certification. Request and result bodies are not stored.

Inspect one supplied x402-v2 exact-payment challenge against an explicit expected HTTPS resource, EVM CAIP-2 network, asset, payee and maximum price. Checks both URL declarations, structure and payment-policy fields only; no live probe, payment, facilitator verification or server-authenticity claim.

Exact rational expected-yield and cost arithmetic for up to 16 scenarios and 12 sequential conditional reject rates. All batch units incur unit cost; rejected units incur an additional penalty. Reports differences from the first scenario and undefined cost per good unit at zero yield. Declared assumptions, not a production forecast.

Check one structured public or synthetic low-stakes experiment plan for timing, comparator, outcome and analysis declarations. Returns deficiencies and an integrity receipt. No registration, trusted timestamp, prediction, power analysis or scientific validation.

Multiply or divide two seven-component SI dimension vectors and compare with the expected output dimension. No unit conversion, formula validation, scale-factor inference or physical-model certification.

Compute binary Brier score and count-weighted ECE for up to 256 declared held-out score/outcome pairs. Supports probability or percent scores, normalized to probabilities. Equal-width bins use exact rational boundaries: lower inclusive, upper exclusive, final bin includes 1. Empty bins report null means/gaps. No clinical validity claim.

Classify up to 100 declared measurement intervals against tolerances as pass, fail or hold. Integer millimetres; uncertainty is an absolute interval half-width, not a confidence level. No sensor verification or engineering approval.
