Every agent-payable API.

CRW — Discover the URLs of a website without scraping content (sitemap + crawl fallback). Pass `url`; optional `maxDepth`, `useSitemap` (default true), `timeout` (seconds, default 120). Recon step before targeted crw/scrape or crw/crawl.

Verify an email address's deliverability via Icypeas (SMTP-level). Pass `email`. Returns `{ item: { _id } }` immediately — the search runs async. KEEP POLLING icypeas/result with that `id` (every 3-5s; Icypeas caps reads at 30/min) until `status` leaves NONE/SCHEDULED/IN_PROGRESS. FOUND/DEBITED = hit, NOT_FOUND/DEBITED_NOT_FOUND = processed but empty. Second verification rung next to tomba/email-verifier — same price, different infrastructure; cross-check risky addresses before a send.

CRW — Search the web and optionally scrape the hits in one call. Pass `query`; optional `limit` (1-20, default 5), `tbs` (freshness: qdr:h|d|w|m|y), `sources` (web|news|images), `lang`, and `scrapeOptions` ({ formats, onlyMainContent }) to return full page content per hit instead of snippets.

ScrapingAnt — Scrape a URL through a managed headless-Chrome cluster (datacenter proxies). Pass `url`; optional `browser` (default true — set false for plain HTTP fetch), `wait_for_selector` (CSS selector to await), `js_snippet` (base64 JS to execute on the page), `block_resource`, `proxy_country` (2-letter), `timeout` (5-60s), `cookies`, `return_page_source`. Returns the rendered page as `{ raw: "<html>…" }`. For Cloudflare/anti-bot-walled pages use scrapingant/scrape_residential.

Google Trends (via x402atlas) — search-demand data: /trend, /interest-by-region, /related-queries, /related-topics. GET { endpoint, keyword, ... }. ~5¢ caps. Use for demand/market research alongside exa search.

Find a person's professional email via Icypeas from their name + company. Pass `firstname` and/or `lastname` plus `domainOrCompany` (domain preferred, e.g. stripe.com). Returns `{ item: { _id } }` immediately — the search runs async. KEEP POLLING icypeas/result with that `id` (every 3-5s; Icypeas caps reads at 30/min) until `status` leaves NONE/SCHEDULED/IN_PROGRESS. FOUND/DEBITED = hit, NOT_FOUND/DEBITED_NOT_FOUND = processed but empty. Results carry the email(s) with a certainty grade (ultra_…

CRW — Structured extraction over up to 10 URLs using an LLM. Pass `urls` plus `prompt` (natural language) and/or `schema` (JSON schema); optional `basis: true` for per-field source evidence. Usually returns the extracted objects INLINE and already complete: `{ results: [{ url, status: completed, data }] }` — read `data` directly, do not poll. The extracted object may be nested one level (`data.data`) on multi-URL calls; unwrap defensively. If a call instead returns `{ id, status: processing }`,…

Anthropic — Claude Messages API, keyless pay-per-call (price varies by model + tokens). Pass standard /v1/messages params: `model` (e.g. claude-sonnet-5), `max_tokens`, `messages`.

Scan a domain for its ROLE-BASED email addresses via Icypeas (contact@, support@, admin@, …) — generic inboxes, not people. Pass `domainOrCompany`. Returns `{ item: { _id } }` immediately — the search runs async. KEEP POLLING icypeas/result with that `id` (every 3-5s; Icypeas caps reads at 30/min) until `status` leaves NONE/SCHEDULED/IN_PROGRESS. FOUND/DEBITED = hit, NOT_FOUND/DEBITED_NOT_FOUND = processed but empty. Complements tomba/domain-search (which lists PEOPLE at the company); use this …

Bright Data Web Unlocker — Fetch a page that actively BLOCKS scrapers: Cloudflare/DataDome/PerimeterX walls, CAPTCHA challenges, aggressive bot detection, geo-fenced content. Bright Data rotates residential exit IPs, solves challenges and retries internally, then returns the final page as `{ raw: "<html>…" }`. Pass `url`; optional `country` (2-letter geo), `render` (execute JS first), `format` ("raw" page, default, or "json" for their envelope with status/headers). This is the FIRST escalation …

TheirStack — Search job postings across thousands of career sites and job boards (hiring signals, recruiting, market research). REQUIRED: `limit` (1-10, vendor bills per job returned) plus at least one of `posted_at_max_age_days`, `posted_at_gte`/`lte`, `company_domain_or`, `company_linkedin_url_or`, `company_name_or`. Rich filters: `job_title_or`, `job_description_pattern_or` (regex), `job_technology_slug_or` (case-sensitive slugs — resolve via theirstack/tech-catalog), `job_country_code_or` (…
