Durable asynchronous GPU-job submission. Settlement means the job was accepted and a job_id was returned; it does not mean the eventual PINN result converged or passed validation.

Search a bounded Crossref snapshot for research-paper DOI metadata with stable DOI links, source provenance and conservative linked-work rights fields. Returns metadata only and excludes abstracts and full text.

Retrieve one sanitized archive metadata record by asset id, including content hash, readiness state, field inventory summary and evidence flags.

Search recent UK property sale prices from HM Land Registry -- property type, price, town, district, and county. Published under the Open Government Licence v3.0. Address-line fields (postcode, street, house name/number) are deliberately excluded, since Land Registry's own licensing note flags those as carrying a separate Royal Mail restriction beyond the OGL grant on the transaction data itself.

Search macroeconomic indicator values (GDP, inflation, unemployment, population) across eight major economies and multiple recent years. Published under CC BY 4.0, explicit commercial reuse permitted.

Find source-linked scientific datasets by topic. Returns structured metadata pointers, declared licence fields, provenance and freshness without redistributing dataset files.

Find source-linked scientific machine-learning model records by topic. Returns metadata and provenance pointers only; model weights are not downloaded or resold, and missing licence evidence remains unknown.

Search a bounded snapshot of NVD (NIST) CVE records merged with the complete CISA Known Exploited Vulnerabilities list -- description, CVSS severity, and whether the CVE is known to be actively exploited in the wild.

Search a bounded, normalized snapshot of significant recent earthquake events with magnitude, time, depth, location, stable USGS links and provenance. Event-level reuse rights remain unknown because ComCat includes contributing seismic networks.

Find source-linked scientific software and repositories by topic. Returns metadata, declared licence evidence and provenance pointers without downloading or reselling repository contents.

Check a specific dataset, paper, repository, or model URL against the indexed open-science corpus and receive a conservative, source-linked commercial-use and redistribution status. Never infers permission from an absent or ambiguous licence -- returns unknown rather than guessing.

Search a bounded NIH RePORTER snapshot for federally funded biomedical research grants -- title, funded organization, administering NIH institute, award identifiers, and dates -- across every disease area and biomedical discipline, not one narrow field. Metadata only.

Blended event probability across Kalshi and Polymarket for one market — Liquidity-weighted blend of venue implied probabilities for a canonical market slug, with per-venue detail, cross-venue divergence, and the last 1h move. Resolved markets return 410 RESOLVED with the outcome. Find slugs via /v1/probability/search.

Pay with base

Historical revealed signal snapshots (commit-reveal hash chain): past BUY/SELL/HOLD + confidence across major pairs, each with its verifiable hash. Bulk pay-per-call data for AI agents (USDC on Base).

Real-time perpetual funding rates + mark price for any Binance futures symbol. Essential for delta-neutral and basis-trading agents. Free source, deterministic, instant JSON. $0.01 USDC via x402 on Base. SYNTHORA. First 3 calls FREE per wallet — send header X-WALLET: 0x<addr>. No charge on upstream failure.

Real-time mempool anomaly score — gas spikes, pending whale swaps, MEV signals, contract deploy bursts. Designed for 5-second polling.

Timeout test endpoint (wait-1m)

All-in-one trust intelligence for x402 services: the complete validation dataset (100+ services graded A-F with real purchase tests, on-chain proof tx hashes, response quality and a how-to-buy guide) PLUS, if you send a 'resource' URL, a fresh verification of that service (passive probe + real micro-purchase + LLM grade) included in the same response.

Detect when an Apify Actor, API, scraper or data feed breaks, goes stale or silently changes shape. One paid call returns a verdict with the evidence behind it, so an agent can decide whether a data source is still trustworthy before acting on it. Works with any HTTP endpoint; 35+ pre-wired vendors (OpenAI, Anthropic, Stripe, GitHub) are a head start, not a limit. Schedule it on your own cadence for continuous monitoring of breakage, staleness and drift.
