## Respond.io

Most B2C companies end up chatting with customers across half a dozen apps, and the result is missed messages, duplicated work and no single view of the relationship. Respond.io addresses that by consolidating WhatsApp, TikTok, Instagram, Facebook Messenger, Telegram, Viber, Line, email and website chat into one shared inbox. Every contact, conversation and deal lives in one place, colleagues can assign and hand off threads internally, and a built-in CRM keeps lead status, tags, custom fields and lifecycle stage attached to the person rather than to the app they messaged from.

AI is woven through the platform rather than bolted on. AI agents greet new enquiries, ask qualifying questions, route the conversation to the right team or salesperson, and take care of repetitive requests like order status or opening hours. An AI-powered contact automation layer can follow up with leads that went quiet, tag conversations automatically and trigger workflows when a customer replies. For marketing teams, broadcast campaigns and click-to-chat links on ads let one message reach thousands of customers while replies still land in a human-operated inbox with full context.

Deployment is channel-agnostic and aimed at operations rather than engineering. Businesses connect their own WhatsApp Business API number or social accounts, build workflows with a no-code builder, and add teammates with role-based permissions. Multi-channel reporting shows response times, resolution rates and campaign performance per channel, which helps teams spot where the real bottlenecks are. Pricing is freemium: a free trial and entry-level tiers exist, with paid plans scaling by number of users and monthly active contacts, and WhatsApp messaging costs handled separately by the provider.

**Pricing & Plans:** Freemium with a free trial. Paid tiers scale by users and monthly active contacts, and WhatsApp messaging fees are billed separately by the channel provider.

- **Unified team inbox:** Bring WhatsApp, TikTok, Instagram, Facebook, Telegram, email and web chat into one shared inbox so no customer thread gets lost between apps.
- **AI agents and automation:** AI agents qualify leads, answer routine questions, route to the right teammate and follow up automatically when conversations go quiet.
- **Contact lifecycle CRM:** Track tags, custom fields, lead status and lifecycle stage per contact, and move deals through a pipeline without a separate CRM.
- **Broadcast campaigns and click-to-chat:** Reach thousands of customers with one message, and capture new leads directly from social ads and website links.
- **Reporting and analytics:** Measure response and resolution times, agent workload and campaign performance across every connected channel.

**Strengths:** Genuinely broad channel coverage, including WhatsApp Business API and social apps B2C customers actually use; AI agents handle routine qualification and follow-up work alongside, not instead of, human teammates; Built-in contact CRM and pipelines reduce the need for a separate tool; Multi-channel analytics make it easier to prove where revenue comes from

**Limitations:** WhatsApp messaging costs are separate from the platform subscription and can add up; Pricing scales with monthly active contacts, so high-volume contact lists get expensive; Teams wanting deep custom workflow logic may hit the limits of the no-code builder

## Serpex

Serpex provides two core endpoints behind a single API key: a Search endpoint that returns live web results as structured JSON, and an Extract endpoint that converts any URL into clean, readable markdown for AI ingestion. A standard search consumes one credit, and pulling page content along with results lets teams go from discovery to ingestion without juggling a second scraping vendor.

The service is positioned around affordability and throughput. Its published tiers scale from roughly $0.80 per 1,000 requests on small top-ups down to around $0.50 per 1,000 on the $500 tier, with custom pricing for very high volume. Serpex advertises automatic fallback across multiple underlying search sources, so if one source returns nothing the request fails over to another, along with retries and per-source health monitoring.

For developers, there are SDKs and integrations for Python, JavaScript, MCP and LangChain, plus a REST API. New accounts receive free trial credits without a card, and credits are described as non-expiring with a short money-back window on purchases.

**Pricing & Plans:** Pay-as-you-go credit model with a free trial (200 free credits, no card). Published tiers: Starter ~$0.80 per 1,000 requests ($5 top-up), Standard ~$0.65 per 1,000 ($50 top-up) and Scale ~$0.50 per 1,000 ($500 top-up); enterprise volume from ~$0.20 per 1,000. Credits are non-expiring and only successful requests are billed.

- **Search API returning structured JSON:** Send a query and receive live web results as clean, structured JSON that is ready for parsing, ranking or feeding into a model.
- **Built-in content extraction:** Convert any URL into clean, readable markdown in the same API key, removing boilerplate so retrieved text is directly usable for RAG and summarization.
- **Automatic source fallback:** Requests are routed across multiple underlying search sources with health monitoring and automatic retries, so a single empty source does not break your pipeline.
- **Developer SDKs and integrations:** Official libraries and snippets for Python, JavaScript, MCP and LangChain make it a few lines of code to add live search to an agent or app.
- **Pay-as-you-go credits:** Only successful requests consume credits, credits do not expire, and volume discounts scale from small top-ups up to high-throughput plans.

**Strengths:** Search and extraction in one API key, reducing vendor sprawl; Competitive pay-as-you-go pricing with volume discounts; Credits never expire and failed requests are not billed; Automatic fallback and retries reduce pipeline fragility

**Limitations:** No ability to pin a specific search engine source; engine selection is handled automatically; Free tier is a credit-based trial rather than an unlimited free plan
