Endpoint (Agent Interface)

CODEBLOCK0

Payment Flow (x402 Protocol)

This endpoint uses HTTP 402 Payment Required:

1. 1. First request (no payment header) -> Server returns 402 with payment requirements JSON
2. Client signs the payment requirements (EIP-712) -> Produces a INLINECODE1
3. Retry with PAYMENT-SIGNATURE header -> Server verifies, settles, returns result JSON

When using @springmint/x402-payment (Node.js) or x402-sdk-go (Go), the flow is handled automatically.

Result Filter Values

Filter types: discussions, faq, infobox, news, query, videos, web, INLINECODE61

CODEBLOCK5

Location Headers (Optional)

For location-aware results, add these headers. Lat/Long is sufficient when coordinates are known — the other headers are only needed as a fallback when coordinates are unavailable.

Header	Type	Description
INLINECODE62	float	User latitude (-90.0 to 90.0)
INLINECODE63

float | User longitude (-180.0 to 180.0) |
| X-Loc-Timezone | string | IANA timezone (e.g., "America/San_Francisco") |
| X-Loc-City | string | City name |
| X-Loc-State | string | State/region code (ISO 3166-2) |
| X-Loc-State-Name | string | State/region full name (e.g., "California") |
| X-Loc-Country | string | 2-letter country code |
| X-Loc-Postal-Code | string | Postal code (e.g., "94105") |

Priority: X-Loc-Lat + X-Loc-Long take precedence. When provided, downstream services resolve the location directly from coordinates and the text-based headers (City, State, Country, Postal-Code) are not used for location resolution. Provide text-based headers only when you don't have coordinates. Sending both won't break anything — lat/long simply wins.

JSON Example

CODEBLOCK6

Mixed Response

The mixed object defines the preferred display order of results across types. It contains three arrays:

Array	Purpose
INLINECODE147	Primary result list (ordered sequence of results to display)
INLINECODE148

Results to display above main results |
| side | Results to display alongside main results (e.g., infobox) |

Each entry is a ResultReference with type (e.g., "web", "videos"), index (into the corresponding result array), and all (true to include all results of that type at this position).

Search Operators

Operator	Syntax	Description
Site	INLINECODE157	Limit results to a specific domain
File extension

ext:pdf | Results with a specific file extension | | File type | filetype:pdf | Results created in a specific file type | | In title | intitle:python | Pages with term in the title | | In body | inbody:tutorial | Pages with term in the body | | In page | inpage:guide | Pages with term in title or body | | Language | lang:es | Pages in a specific language (ISO 639-1) | | Location | loc:us | Pages from a specific country (ISO 3166-1 alpha-2) | | Include | +term | Force inclusion of a term | | Exclude | -term | Exclude pages containing the term | | Exact match | "exact phrase" | Match the exact phrase in order | | AND | term1 AND term2 | Both terms required (uppercase) | | OR / NOT | term1 OR term2, NOT term | Logical operators (uppercase) |

Set operators=false to disable operator parsing.

Goggles (Custom Ranking)

Goggles let you re-rank search results — boost trusted sources, suppress SEO spam, or build focused search scopes.

Method	Example
Hosted	INLINECODE172
Inline

--data-urlencode 'goggles=$discard\n$site=example.com' |

Hosted goggles should be hosted on a public URL and include ! name:, ! description:, ! author: headers. Inline rules need no registration.

Syntax: $boost=N / $downrank=N (1–10), $discard, $site=example.com. Combine with commas: $site=example.com,boost=3. Separate rules with \n (%0A).

Allow list: $discard\n$site=docs.python.org\n$site=developer.mozilla.org — Block list: INLINECODE185

Resources: See your upstream provider's Goggles documentation.

Rich Data Enrichments

For queries about weather, stocks, sports, currency, etc., use the rich callback workflow:

CODEBLOCK7

Supported Rich Types: Calculator, Definitions, Unit Conversion, Unix Timestamp, Package Tracker, Stock, Currency, Cryptocurrency, Weather, American Football, Baseball, Basketball, Cricket, Football/Soccer, Ice Hockey, Web3, Translator

Rich Callback Endpoint

CODEBLOCK8

Parameter	Type	Required	Description
INLINECODE186	string	Yes	Callback key from the web search rich.hint.callback_key field

Use Cases

• - General-purpose search integration: Richest result set (web, news, videos, discussions, FAQ, infobox, locations) in one call. For RAG/LLM grounding, prefer llm-context.
• Structured data extraction: Products, recipes, ratings, articles via schemas and typed fields on results.
• Custom search with Goggles: Boost/discard sites with inline rules or hosted Goggles for fully customized ranking.

Notes

• - Pagination: Use offset (0-9) with count to page through results
• Count: Max 20 for web search; actual results may be less than requested
