io.github.webberdesign/webbersites-x402-data-api

Exact financial + token math. POST {op:…}: compound (growth with per-period contributions), amortize (payment, total interest, schedule), npv, irr (deterministic bisection) — and token_units: exact decimal↔base-unit conversion via BigInt for any token decimals (ETH 18, USDC 6), the 18-decimal math that float64 silently corrupts. Iterative series computed exactly, never guessed. ($0.005 per call, paid via x402)

Exact descriptive statistics — LLMs cannot reliably sum 200 numbers; this can. POST {values:[…]} for count/sum/mean/median/stddev/percentiles; {x:[],y:[]} for Pearson correlation + linear regression; {rows:[…], field} for object arrays — or {collection, field?} to run stats DIRECTLY ON YOUR DATASTORE collection (the paying wallet is the identity; reading extends its life 30 days). Up to 100k values, Kahan-summed. ($0.005 per call, paid via x402)

Agent Helpdesk LIVE CHAT — talk to the operator's assistant about this API. $0.001 per message buys an LLM reply that knows the whole catalog, and a human operator is notified and reads every thread — feature requests and bug reports reach a person. We build tools agents need, on demand. Body: {message, session?, agent?}; pass the returned 'session' back to continue a conversation (kept ~1 hour). Replies are capped at ~150 words. ($0.001 per call, paid via x402)

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. ($0.005 per call, paid via x402)

LLM CODE DEBUGGING — POST {code, error} and get a diagnosis: what is wrong, the root cause, and a concrete fix with corrected code. Paste the failing snippet plus the error message or stack trace; any language, up to 20,000 chars combined. Optional {language} and {context} ('happens only on the second call'). Fast cheap LLM under the hood. Want deterministic no-AI lint instead? POST /api/lint/:language ($0.002). ($0.01 per call, paid via x402)

IMAGE DESCRIPTION (vision AI) — POST {url} or {image_base64} and get back what is IN the image: a detailed description, notable objects, visible text transcribed, colors, and style. Or ask a specific {question} about the image ('what error is on this screen?'). PNG/JPEG/GIF/WebP up to 5 MB. For agents without eyes: alt text, screenshot triage, image search and moderation. Fast vision model; the x402 payment IS the auth. ($0.02 per call, paid via x402)

CUSTOM EXTRACTION — POST {content, schema} and get structured JSON back. Define fields as {"company":"string","total":"number","due_date":"date"} (types or plain-language descriptions) and the engine pulls them from any unstructured text: emails, invoices, job posts, resumes, chat logs. Missing fields return null — never invented. Content up to 16,000 chars, 40 fields max. Parsing a PDF/DOCX/CSV by URL first? GET /api/extract ($0.02). ($0.01 per call, paid via x402)

AI IMAGE GENERATION — POST {prompt} and get back a PNG, base64 in JSON (?raw=1 for raw bytes). Gemini 2.5 Flash Image (nano-banana): photoreal scenes, illustrations, product shots, UI mockups — renders text in images well. Optional {aspect_ratio}: 1:1 (default), 16:9, 9:16, 4:3 + 6 more. Reference images: pass {url} or {image_base64}, or up to 3 in {reference_images}, to edit, restyle, or compose ('put this product on this beach'). The x402 payment IS the auth. ($0.07 per call, paid via x402)

Icon generator: pick a Font Awesome Free icon (by search query or exact name) plus background color(s) and get an app-icon-ready asset — SVG source + PNG base64, default 1024x1024 opaque squircle (iOS-ready). Options: 1-2 background colors (2 = gradient), fg glyph color, shape (squircle/rounded/circle/square/transparent), size 64-1024, padding. Returns alternatives when resolved via search. ($0.01 per call, paid via x402)

Elixir lint / debug kit: POST {code}, get the bugs back with line numbers. Deterministic static analysis — code is parsed, never executed, no AI. Catches unbalanced do/end and brackets, missing do, 'return', '+' string concat, trailing commas, field assignment, = vs == in conditions and guards, block-scoped rebinding (the classic), charlist vs String mixups, unused variables. Errors, warnings and hints with fixes. Max 128 KB. ($0.002 per call, paid via x402)

JavaScript / Node lint: POST {code}, get the bugs back with line numbers. Syntax errors come from the real V8 parser (compile-only — code is never executed), plus deterministic checks: loose == coercion, assignment in conditions, comparisons with NaN, const reassignment (runtime TypeError), var pitfalls, unused variables, leftover console.log. Handles ESM imports, template literals, regex. No AI. Max 128 KB. ($0.002 per call, paid via x402)

Liquid / Shopify theme lint: POST {code}, get the bugs with line numbers. Deterministic — never rendered, no AI. Catches unbalanced/misnested blocks, unknown tags/filters with did-you-mean, the JS-isms every dev writes in Liquid (&&, !, ternaries, arithmetic in output, parens in conditions), deprecated img_url/include, and FULL {% schema %} validation: setting types, duplicate ids, range/select rules, blocks, presets. POST bare schema JSON to test just a schema. Max 128 KB. ($0.002 per call, paid via x402)

PHP lint: POST {code}, get the bugs back with line numbers. Deterministic static analysis — code is never executed, no AI. Catches SQL injection (request data interpolated into query strings), the removed mysql_* API, unbalanced braces, '+' string concat, = vs == in conditions, type-juggling loose comparisons, eval/extract on request data, unused variables, leftover var_dump. Understands PHP tags, heredocs, interpolation. Max 128 KB. ($0.002 per call, paid via x402)

HTML → Shopify section converter. POST static HTML; get back a drop-in theme section: headings, paragraphs, images, links, and buttons are lifted into {{ section.settings.* }} references and a matching {% schema %} is generated with your original content as the defaults — immediately editable in the Shopify theme editor. Deterministic transform, no AI; output is self-linted before it's returned. ($0.01 per call, paid via x402)

Logo generator: POST a company name (+ optional tagline), an icon (search query or exact Font Awesome name), 1-3 brand colors (hex or CSS names), a mark shape (squircle/rounded/circle/square/transparent) and a layout — icon above/below the name (square logo) or beside it (wide lockup) — and get a finished logo as SVG + PNG. Text set in one of six curated open-license fonts (named or randomly rotated), rendered as vector paths. ($0.02 per call, paid via x402)
