How this service works

Pay-per-call tools for AI agents, 31 in all: read web pages and RSS feeds, OCR, PDF text, transcription; email, phone and domain checks; UK, Irish and Polish company lookups and UK risk reports; website contacts, tech stack and SEO audits; PageSpeed; AI review, job post and row enrichment; data cleaning, joins, dedupe and diffs; US and EU compliance rules. No account or API key: pay each call in USDC on Base over x402.

Output

A JSON object containing: 'rows' (the kept rows after all filters, transforms, sort, dedup, offset, and limit are applied) and a 'summary' object with inputRowCount, keptRowCount, excludedByFilter, duplicatesRemoved, droppedByLimit, filtersApplied, transformsApplied, sortedBy, filterCombineMode, transformIssues, and warnings.

Example use cases

Clean scraped product listings

“I scraped 400 product rows from a site and need to clean them up — filter out any rows where price is empty, cast the price field from strings like '$1,234.50' to a real number, sort by price ascending, and deduplicate by product SKU keeping the cheapest one.”

Segment leads by region and score

“Here are 300 CRM lead records as JSON. Filter to only leads where country equals 'UK' and score is greater than 70, rename 'lead_score' to 'score', and return the top 50 sorted by score descending.”

Normalize survey response data

“I have 150 survey response rows where some text fields have mixed case and extra whitespace. Can you trim all text fields, convert the 'status' field to lowercase, filter out rows where 'response' is empty, and return the cleaned rows with a count of how many were dropped?”

Endpoint

When to prefer

Choose this endpoint when you have a JSON array of up to 500 rows and need to combine filtering, field transformation, sorting, and deduplication in a single atomic call without writing custom code. It is especially useful inside agentic pipelines that process scraped data, API responses, or spreadsheet exports before passing them downstream. Prefer it over writing ad-hoc JavaScript or Python when you want auditable drop-reason counts. If you need AI-powered per-row classification rather than deterministic rules, use the sibling AI-transform endpoint instead.

Side effects

More than 500 rows sent — batch must be split
Invalid operator name in filter — call list_capabilities to see all 25 operators
Invalid transform op — call list_capabilities to see all 26 operations
Dot-path field reference doesn't exist in rows — row silently skipped or warning returned
Expression in compute op references undefined field — transform issue recorded in summary
Malformed JSON body — HTTP 400 returned
Payment not attached or insufficient — HTTP 402 returned (minimum $0.002 USDC)

Input

Schema · Request body

Field	Type	Description
rows	array	The rows to process. Each row is a JSON object. Keys may differ between rows.
limit	integer	Return at most this many rows.
offset	integer	Skip this many rows after filtering and sorting.
sortBy	array	Sort the kept rows, for example [{"field":"price","direction":"desc"}].
filters	array	Conditions a row must satisfy to be kept, for example {"field":"country","operator":"equals","value":"UK"} or {"field":"price","operator":"greaterThan","value":100}. Dot paths like "address.city" work. Call list_capabilities for all 25 operators.
distinctBy	array	Keep only the first row for each combination of these fields. Applied after sorting, so sorting first lets you keep the newest row per key.
transforms	array	Transform steps applied to every row, in order. Each step is an object with an "op" key, for example {"op":"cast","field":"price","to":"number"} or {"op":"compute","field":"total","expression":"price * qty"} or {"op":"rename","from":"e_mail","to":"email"}. Call list_capabilities for all 26 operations.
lenientNumbers	boolean	On by default: values like "$1,234.50", "49 USD" and "12%" are read as numbers. Set false to require real numeric values.
filterCombineMode	string	Whether a row must match every filter (AND, the default) or any one of them (OR).
caseSensitiveFilters	boolean	Text comparisons are case-insensitive by default. Set true to make them exact.
