Funding-arb SIGNAL for crypto perpetuals — the cross-venue funding spread per pair, set against public round-trip taker fees, with periods-to-breakeven, ranked by the 8h-normalized spread. Liquidity is not assessed: depth sizing was withdrawn on 2026-09-16, so check the books before sizing. A derived outcome, not a profit forecast.
Structured JSON from a web page or text, with exactly the fields you ask for. $0.01 USDC per call on Base, no API key. POST JSON { schema: { field: type, ... } (required), plus url or text }. Returns { data } with your schema's keys (null when a field is not in the source), the model used and latency_ms. Page fetch capped at 10 s, whole call at 45 s, so it never hangs.

Email validation for signups, lead lists and CRM cleaning, no API key. $0.01 per address.
Scores variables by their importance for a model or dataset.
Compare two supplied public-source text versions and return bounded, hash-backed evidence of change.
OCR extraction from scanned PDF documents (English). Uses Tesseract to read text from image-based pages that have no embedded text layer. Returns structured text and metadata. Ideal for invoices, receipts, contracts, and legacy documents. $0.05 per extraction.
Extract structured text, tables, and metadata from any PDF URL. Returns page-by-page text content, detected tables as JSON arrays, and document metadata (title, author, page count). No PDF library or OCR setup needed — pay per extraction. AI agent API for document intelligence and data extraction
Returns clean, normalized datasets of AI model benchmarks, pricing, leaderboard scores, and Ethereum EIPs, parsed from sources that are costly to scrape.

Deterministic data-format conversion — the shape work an LLM cannot do reliably token-by-token. POST {data, from, to}: JSON, NDJSON, CSV, TSV, or a SQL INSERT dump in; any of the same out. Handles RFC 4180 quoting (commas, quotes, newlines in values), flattens nested objects to dot-notation columns, unions ragged records into a stable column set, and parses SQL string literals with '' and \' escapes. No AI, no network — same input, same bytes, every time.
Extract text and metadata from PDF documents. Supports page-specific extraction and returns structured content.
Verify a claim against supplied context or live web evidence.
Dated changes recorded for one entity since a date, with the earlier value, the later value, when each was seen and the source
Immutable aggregate timestamp-coverage report with cutoff and reproducibility digest.
OCR a scanned PDF into clean text (Tesseract, English, machine-printed documents). Up to 25 pages per call. PDFs that turn out to have a text layer are extracted the fast way at the same price.
