How MorphAPI Works

Click through the three stages of the deterministic extraction pipeline.

Stage 01 // Headless Browser Inspection

Real Chromium Rendering. Zero Scraping Guesswork.

MorphAPI navigates to target URLs using isolated Playwright workers. It renders dynamic JavaScript, client-side hydration, and dynamic DOM trees before testing candidate selectors.

[02 // FAILURE_ANALYSIS_LAB]///THE_2AM_OUTAGE_PROBLEM///AUTONOMOUS_RESILIENCE

THE ANATOMY OF A WEB-TO-API FRACTURE.

Every web scraper eventually fails because websites are living, unstable documents. When frontend teams redesign or randomize CSS hash names, hardcoded selectors die—taking production pipelines with them. MorphAPI turns fragile scrapers into self-healing, type-safe API infrastructure.

TRADITIONAL SCRAPER // FRAGILE

STATUS: 502 CRASH

$ curl https://api.legacy-scraper.internal/v1/pricing

HTTP/1.1 502 Bad Gateway: Selector '.price-tag-v1' matched 0 DOM nodes.

[-]Hardcoded CSS selectors break permanently on frontend class renames.
[-]Silent data drops corrupt downstream databases until an on-call engineer wakes up.
[-]Manual selector repair requires hours of DevTools inspection and redeploy cycles.

MORPHAPI GATEWAY // AUTONOMOUS

STATUS: 200 OK (SELF-HEALED)

$ curl https://gateway.morphapi.local/v1/extract/pricing

HTTP/1.1 200 OK: Playwright AST extraction verified. Version promoted to v2.

[+]Fast-path deterministic execution (<400ms) with zero LLM token cost during normal traffic.
[+]LangGraph state machine isolates mutated DOM nodes and hypothesizes resilient selectors.
[+]Unified AST diff inspection with human-in-the-loop review or autonomous auto-promotion.

[03 // ARCHITECTURE_AST]///DUAL_ENGINE_PIPELINE///SYSTEM_SPECIFICATION

THE DUAL-ENGINE GATEWAY PIPELINE.

Engineered as a hybrid runtime: the speed and determinism of raw headless browser evaluation paired with the spatial reasoning of high-parameter generative AI when layouts break.

MODULE 01 // FAST-PATH DETERMINISTIC EXTRACTION

< 400MS // MODEL-FREE

Standard production traffic does not invoke an LLM. Playwright evaluates active CSS/XPath selector maps directly on rendered headless Chromium DOM. 100% deterministic, zero hallucination risk, and zero inference cost.

Latency: <400ms

Cost: $0.00 / req

Engine: Chromium AST

Validation: Pydantic v2

MODULE 02 // NVIDIA NIM SPATIAL & VISUAL INFERENCE

LLAMA-3.1-70B // SELECTOR SYNTHESIS

When DOM mutation causes 0 matches, the sanitized DOM tree is passed to NVIDIA NIM. The model infers visual-spatial coordinates and candidate CSS selectors based on semantic content and structural container patterns.

Model: Llama 3.1 70B

DOM Sanitizer: 42kb AST

Hypothesis Rate: 99.4%

Inference: GPU NIM

MODULE 03 // LANGGRAPH AGENTIC HEALING LOOPS

STATE MACHINE // HUMAN APPROVAL GATE

A cyclic graph manages the self-healing workflow: detect failure → isolate DOM → propose candidates → verify in Playwright → compute AST diff → hold at human review gate or auto-promote per endpoint policy.

Stages: 6 Steps

Diff Engine: Unified AST

Approval: Configurable Gate

Persistence: SQLite Async

MODULE 04 // SSRF ENCLAVE & SCOPE FIREWALL

RFC 1918 FILTER // CLOUD METADATA QUARANTINE

Browser workers operate within a locked network jail. DNS resolution enforces private subnet blocking (127.0.0.0/8, 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16, AWS 169.254.169.254) with strict wildcard scope matching.

Subnets: RFC 1918 Block

DNS: Pre-flight Resolve

Scope: Regex Wildcards
