#enrichment

Turn an email address into its Gravatar avatar and public profile. Pass an email and the service normalises it, computes the MD5 and SHA-256 hashes Gravatar uses, builds a ready-to-use avatar URL, checks whether a custom Gravatar actually exists, and fetches the public profile when present — display name, username, profile URL, location, about text, linked accounts and photos. A dedicated avatar endpoint builds just the image URL with full options: size (1-2048), a default image (identicon, monsterid, robohash, retro, mp, blank, 404, or your own URL), rating and force-default. Ideal for user-profile enrichment, comment systems, contact cards, team pages and onboarding — showing a real avatar from nothing but an email. A Gravatar lookup — distinct from deterministic avatar/identicon generation (avatar), which renders a brand-new image from a seed rather than fetching the avatar a person actually chose. No upstream key, no cache.

The STRING protein–protein interaction database as an API — the curated and predicted network of functional associations between proteins, powered by the official STRING API. Resolve gene or protein names to STRING identifiers with annotations; get a protein's top interaction partners with a combined confidence score and per-channel evidence (experimental, curated databases, co-expression, text-mining, gene fusion, neighbourhood and co-occurrence); build the interaction network among a set of proteins as scored edges; run functional enrichment of a gene set over Gene Ontology, KEGG, Reactome, Pfam, InterPro and more with p-values and false-discovery rates; and score homology between proteins. Covers 12,000+ organisms (default human, NCBI taxon 9606). Ideal for systems-biology and network-biology pipelines, gene-set and pathway analysis, drug-target and disease-gene research, and bioinformatics dashboards.

Enrich a first name with predicted gender, age and nationality — with confidence probabilities and an optional country bias for higher accuracy. One combined call returns all three. Ideal for CRM enrichment, personalization, form pre-fill, audience analytics and demographic segmentation.
