Every agent-payable API.

Parse a cron expression into human-readable explanation + next N execution times. Algorithmic — instant.

Parse a free-text address into structured components. Returns street, city, postal code, state/province, country. Works with addresses worldwide.

Parse a full name into components: first, middle, last, prefix, suffix, nickname. Handles 'Dr. Karl-Johan von Lindström III' correctly.

Parse ambiguous date strings into ISO 8601. Handles '3/4/25', 'March 4th', '4. mars 2025', '2025-W14'. Detects ambiguity.

Parse an A1 range like "A1:C10" into its start and end cells (normalized so start is the top-left) and its extent — row count, column count and total cell count.

Parse an ISO 8601 duration such as 'P1Y2M10DT2H30M' into its components. Returns a normalized ISO string and totalSeconds — but totalSeconds is null when the duration contains years or months, because those are calendar-variable (use /v1/add or /v1/between for exact date math).

Parse an SPF TXT record ("v=spf1 …") into its qualified mechanisms and modifiers. Records that do not start with v=spf1 or use unknown mechanisms are clean 400s.

Parse dice notation such as "3d6+2", "4d6kh3" (keep highest 3) or "2d20dl1" (drop lowest 1) into structured terms. Malformed notation is a clean 400.

Split YAML front-matter from a document — returns the parsed metadata object and the remaining content body. Malformed YAML is rejected as a clean 400.

Parse human durations like 1h30m for $0.001 USDC. Call when you need this bounded result without an API key or subscription. Returns machine-readable JSON via x402 on Base or Solana. Limitation: results cover only the supplied input or one bounded public endpoint at request time; callers must verify before acting.

Parse a formatted money string back into a number, using the locale's grouping and decimal separators (so '1.234,56' in de-DE → 1234.56). Currency symbols/codes and whitespace are stripped; parentheses or a leading minus mean negative. A string with no numeric amount is a clean 400.

Parse or build URL query strings for $0.001 USDC.

Parse, validate and format a phone number — E.164/national/international/RFC 3966, region and line type (syntactic validation, no carrier lookup).

Parse an SMPTE timecode (HH:MM:SS:FF, or HH:MM:SS;FF for drop-frame) at a given frame rate into its components, total frame count and real-time seconds. Drop-frame is auto-detected from a ';' separator unless dropFrame is set. Out-of-range or non-existent drop-frame values are a clean 400.

Parse a semantic version into major/minor/patch, prerelease and build metadata.
